1st Configuration of my hardware:

For the first configuration of the material, it is necessary to pay attention to 2 important points

1. The configuration of the mobile Internet access of my equipment via the parameters of the SIM card and the Modem.
2. Make sure that your mobile Internet reception is correct in your work area and that your receiver is correctly configured, especially if you work with cards from different operators: Orange, SFR (APN corresponding to the card operator SIM).
3. The configuration of the GPS application via the NTRIP settings of my subscription.
4. Make sure your GNSS receiver is correctly configured (Username, Password, DNS address, mount point). The manufacturer’s manual for your receiver and the delivery note will allow you to configure it correctly.
5. Make sure you are in the work area corresponding to the work area you have subscribed to in the event of a local, departmental or regional subscription.

All of these parameters are described on the delivery note sent to you by our services. Using the user manual for your equipment, follow the instructions to configure all the information step by step. Do not hesitate to contact your distributor who is perfectly familiar with this type of configuration and will help you in this step.

My equipment has already received corrections from the Orphéon network

Your hardware has already been configured correctly and you have already worked by receiving corrections from the Orpheon network, but you are unable to connect.

Here are some simple but important things to check.

1. Make sure that your mobile Internet reception is correct in your work area and that your receiver is correctly configured, especially if you work with cards from different operators: Orange, SFR (APN corresponding to the card operator SIM).
2. Make sure that your GNSS receiver is correctly configured (Username, Password, DNS address, mount point) or that these parameters have not been modified, especially if you share your equipment in a team with other users. The manufacturer’s manual for your receiver and the delivery note will allow you to configure it correctly.
3. Make sure you are in the work area corresponding to the work area you have subscribed to in the event of a local, departmental or regional subscription.
4. Make sure in the case of an hourly package that it has not expired and that you have hourly credit.
5. Make sure that another mobile is not already connected with your username and password: use the Smartphone application or go to the customer portal to see if a mobile is already connected to the network.

The permanent stations do not have a given radius of action insofar as the calculation is done in a network, with uniform precision at any point in the territory. Concretely, the system uses a set of several stations around you to create a cell, in order to obtain solid and consistent data. Thus, whether you are a few meters or a few kilometers from the nearest station has no impact on the quality of service.

Work in network mode within a cell

When you encounter network connection problems, it is essential to be able to determine the source of these problems, which are generally linked to one of the following two reasons:

Mobile Internet:

Before accessing the servers of the Orphéon network, your mobile must first of all be connected to the Internet in a stable manner. When you launch a connection, you can thus, depending on the behavior of your hardware, determine if the problem is related to the mobile connection when, for example:

• You do not receive any error message, your mobile tries to connect without effect. Your authentication request does not reach the Orpheon servers.
• Connection sessions are short and follow one another. This means that the quality of your mobile internet connection is not good or is not stable.
• On connection reports, the server shows the message: “Connection terminated by rover user”

This can come from the distance with the relay antenna of the telephone operator (Orange, SFR or other). This may be due to the quality of the signal provided by the telephone operator; a too weak or choppy signal or fluctuating latencies (data transfer times). You can try using a SIM card from another operator.

In order to determine what is the level of coverage for your mobile internet access in the area in which you wish to work, there are two official sites

1/ The ARCEP website :

2/ the ANFR website

The Orpheon network :

• You receive error or rejection messages related to your authentication or multiple connections.
• On the Orpheon Smartphone application, several Orpheon reference stations are stopped (in red or blue).
• The Orpheon Smartphone application no longer starts or you cannot reach the Orpheon server web page.

This can be due to several factors:

• Check that your subscription or plan is still active.
• Check that you have not left the restricted area of ​​your Local, Departmental or Regional subscription.
• Check that another mobile is not already connected with your credentials.
• Check that the configuration of your mobile corresponds well with the mount point you have selected.
• Check the configuration concerning the IP address has been correctly filled in with a DNS address and not a fixed IP address such as 69.64.185.131 (Spider) or 69.64.125.240 (TPP).

This approach is part of a desire to improve the quality of our services and simplify our exchanges. We hope that this additional information will satisfy you.

The mount point allows you to choose the type of data stream that will be exchanged between your hardware and our server, this corresponds both to the language that the hardware will use but also to the method of calculating the positioning that will be used.

The choice of the mounting point therefore depends on your equipment, its brand, its capacities and the choice of the method of calculation of the positioning that you will use. Each manufacturer will favor a type of correction and the flow of data that will optimize the results of your work. For this, some major manufacturers have developed their own data flow that our servers are able to transmit. There are also standardized and normalized data flows common to all equipment and allowing the same performance to be obtained.

On our delivery notes, we suggest one or more mounting points, so that you can configure them corresponding to your equipment, but you are completely free to choose a different mounting point available.

In most cases all equipment allows you to use VRS (Virtual Reference Station) type mounting points

Mount points available for Topography:

• VRS_RTCM-MSM_FULL (Any Full GNSS hardware)
• VRS_RTCM-3.0_GG (All Hardware)
• VRS_CMRx_GG (Trimble Group Hardware)
• i-Max_RTCM-MSM_FULL (Hexagon Full GNSS group hardware)
• i-Max_RTCM-3.0_GG (Hexagon Group Hardware)

Mount points available for Agriculture:

• VRS_RTCM-MSM_FULL (Any Full GNSS hardware)
• VRS_RTCM-3.0_GG (All Hardware)
• i-Max_RTCM-MSM_FULL (Hardware with Novatel Full GNSS card)
• i-Max_RTCM-3.0_GG (Hardware with Novatel card)
• Plus_pres_RTCM3_GG (All hardware single station)
• Plus_pres_CMRPlus_GG (Trimble group hardware mono station)

In case of wrong choice of mounting point:

• You will not be able to connect to our servers and therefore you will not be able to obtain a correction. You will therefore not have the expected precision. Your position will remain in natural or floating mode (without correction) the material failing to fix the ambiguities. On the Smartphone application, the symbol locating your equipment will be in red.
• You will manage to connect to our servers but the corrections you get will be misinterpreted by your equipment. You will therefore not have the expected precision. On the Smartphone application, your position will apparently be fixed (with correction), the symbol locating your equipment will be in green.

It is therefore essential that the configuration of your equipment is checked to match the correction mode expected and configured on your mobile with the corrections delivered by our servers according to the mounting point you have selected.

If you change the mounting point, check that you have also adapted the configuration of your equipment so that the 2 correspond well.

RTCM-2.x format (DGPS)

This message is the most common way to send DGPS style code corrections for GPS.

Format RTCM-3.1  ( RTK GPS Glonass)

RTCM versions 3.0 and 3.1 focus on optimizing bandwidth usage [6], higher integrity [7] and managing RTK networks

Format RTCM-3.x MSM (RTK Full GNSS)

Message formats were previously limited to the L1 and L2 bands and a single signal per band, which is why it became necessary to use a new universal real-time data format: the MSM (for Multiple Signal Message) which is the new concept of RTCM-3 key allowing to present all GNSS observation data in generic form.

The RTCM-3 MSM standard thus ensures data interoperability with all compatible GNSS receivers by transmitting standardized observations of GPS + Glonass + Galileo + Beidou signals for all L1/L2 and L5 frequencies.

Self-check recommendations

In our recommendations for field phase measurement, we recommend the occupation of all known points in coordinates (RBF, NGF).

To know these points near your site, the IGN provides you with the location of its terminals as well as a wealth of very useful information for the whole of France, Access to the IGN website (click to open the link )

• Control of measurement equipment (Firmware version of GNSS equipment, status of the rod, of the bubble, compliant configuration and configuration)
• Turn on the mobile and stand on a clear point
• Ensure good internet connection and service stability
• Connect to real-time correction services
• Start a first initialization session (8 minutes without cycle jumps for 6 satellites being one fairly widespread minimum recommended value) for subsequent fixing of integer ambiguities
• Centre, bubble, check antenna height and stability
• Perform measurement work while ensuring GNSS measurement conditions: sufficient number of satellites, GDOP < 3 – 4, SNR > 50 (on L1) or 40 (on L2)
• In the event of a cut warning by the receiver or in the event of lifting in a place prone to cuts signal (near trees, buildings, etc.), redo an initialization session
• Reoccupy the first point at the end of the lift
• Reoccupy the important points at least once after at least 20 minutes (see control sheet)
• Occupation of all known points in coordinates (RBF, NGF) (see check sheet)

RGAF09 as standard on the Orphéon network

As of Monday, December 16, 2019 at 06:30 UTC the Orpheon network uses RGAF91

A new format for Full GNSS

Message formats were previously limited to the L1 and L2 bands and a single signal per band, which is why it became necessary to use a new universal real-time data format: the MSM (for Multiple Signal Message) which is the new concept of RTCM-3 key allowing to present all GNSS observation data in generic form.

Format RTCM-2.x (DGPS)

This message is the most common way to send DGPS style code corrections for GPS.

Format RTCM-3.1  ( RTK GPS Glonass)

RTCM versions 3.0 and 3.1 focus on optimizing bandwidth usage [6], higher integrity [7] and managing RTK networks

version 3.x uses a variable-length message format and a single 24-bit cyclic redundancy check (CRC) over the entire message, as opposed to 6-bit parity for each 30-bit word. Like previous versions, the message format begins with an 8-bit extended preamble, followed by a 6-bit reserved area, and then a 10-bit message length that allows up to 1024 bytes of data. The message, each with its privately defined header and data, follows the header and is then limited by the CRC. The saving of data, especially in the case of RTK, is significant, an RTK version 3 correction set is generally half as long as version 2.

Local coordinate systems

As with GPS coordinates, local coordinates or coordinates used in a given country’s mapping system are based on a local ellipsoid, intended to best match the geoid in the area concerned. As a rule, these coordinates are projected onto a plane so as to obtain planar coordinates.

Each country has therefore defined a reference system based on a local ellipsoid to meet its own needs. When using GPS, the calculated position coordinates are based on the WGS84 ellipsoid. Ordinarily, existing coordinates are expressed in a local coordinate system, so the GPS coordinates must be transformed into this local system.

All altitudes measured by GPS are relative to the surface of the WGS84 ellipsoid. These are thus ellipsoidal altitudes. The existing altitudes are generally orthometric altitudes referred to the mean sea level. The mean sea level corresponds to a surface called the geoid, which can be defined as an equipotential surface, that is to say that the value of gravity is constant at all points on this surface. The geoid is irregular in shape and does not correspond to any ellipsoid. The density terrestrial (the distribution of masses) however exerts an influence on the geoid, the level of the latter being higher in very dense regions and lower in low density regions.

This problem is solved by using geoid models to convert ellipsoidal heights to orthometric heights. In less rugged areas, the geoid can be considered constant. In such regions, the use of certain transformation techniques can lead to the production of a height model, the geoid heights can then be interpolated from existing data.

Lambert’s projection

The Lambert projection is also a conformal projection, based on a secant cone with the spheroid. It is ideal for small circular countries, islands and polar regions.

The Lambert projection is defined by:

• false East and false North values

• the latitude of the origin

• the central meridian

• the latitude of the 1st parallel of contact

• the latitude of the 2nd parallel of contact

The False East and False North values ​​are defined so that the origin of the projected system is in the lower left corner as required by convention. This also avoids the presence of negative coordinates. The latitude of the origin defines the latitude of the origin of the projection. The central meridian defines the direction of the north of the grid and the longitude of the center of the projection.

The latitude of the 1st parallel of contact defines the latitude of the first intersection of the cone and the spheroid, in which the scale is preserved. The latitude of the 2nd parallel of contact defines the latitude of the second intersection of the cone and the spheroid, in which the scale is also retained. The scale is reduced in the area between the two contact parallels and increases outside of it. It is conserved on each of the two contact parallels. The scale does not vary in the east-west direction.

List of EPSG codes

EPSG (European Petroleum Survey Group) codes are a list of projection georeferenced coordinate systems used by many GIS software packages.

These codes are notably used in the standards of the OGC (Open Geospatial Consortium).

EPSG: Division of Lambert zones (V1)

EPSG: Division of the 9 zones of the Lambert 93 (V2)

In the configuration of your equipment which will guide your choice of mounting point, the choice of the type of corrections will depend on your equipment, the measurements you are going to perform and the availability of services.

MAC

Initiated by Leica Geosystelms and GEO++ in 2001, the first NRTK standard for network message correction that would overcome the problems of the various existing approaches. Concept based on the notion of master and mobile (Master Auxiliary Concept) allowing the Mobile to receive raw observation data from the nearest Master station in order to perform its correction calculations.

MAX

This Leica Geosystems format is based on the principle of using a cell of several reference stations around the rover with a reference station (the closest). MAX corrections contain all of the cell’s correction information and provide the maximum level of accuracy and reliability for the rover.

These corrections optimize the bandwidth needed to transmit the corrections.

FKP

The oldest FKP method, (Flächen-Korrektur-Parameter) developed by Geo++, consists of the principle of transmissions of a model of errors calculated for the place where the mobile is specifically located. Subsequently, the rover calculates the corrections itself in the same way as in VRS. In addition the correction of a physical reference station is used in combination with the FKPs to calculate the individualized corrections for the position of the mobile.

FKP corrections are transmitted in RTCM 2.3 format. This method which provides the mobile with more information is bandwidth intensive and requires stable communication quality.

i-MAX

Introduced by Leica Geosystems the RTK network corrections are based on the position of the rover are calculated from information relating to a virtual master station created by calculations in close proximity to the rover in order to reduce the length of the baseline and present a level of lower error. The position of the master station can change to follow the movements of the mobile.

Full GNSS compatible corrections transmitted in RTCM-3 MSM format

VRS

With the Virtual Reference Station, a concept introduced by Trimble, the rover interprets and uses network-correction data from a virtual base as if it were operating with a single physical base station on a very short baseline, this which dramatically increases RTK performance. However, it does not create a virtual vector.

Full GNSS compatible corrections transmitted in RTCM-3 MSM format

Format RTCM-2.x (DGPS)

This message is the most common way to send DGPS style code corrections for GPS or FKP

Format RTCM-3.1  ( RTK GPS Glonass)

RTCM versions 3.0 and 3.1 focus on optimizing bandwidth usage [6], higher integrity [7] and managing RTK networks

We have replaced IP addresses with DNS (Domain Name System) addresses. This configuration is now the standard format for setting up on GPS receivers.

So when we switch to our backup system, each user doesn’t have to change their receiver settings, everything is transparent and smooth.

Two DNS are provided to replace the IP address depending on the correction platform used for your equipment:

• Spider Leica platform: ntrip.reseau-orpheon.fr
  or
• Trimble Pivot Platform: ntrip2.reseau-orpheon.fr

We have replaced IP addresses with DNS (Domain Name System) addresses. This configuration is now the standard configuration format to be performed on GPS receivers.

So when we switch to our backup system in the event of a problem on the main server, each user is not obliged to change the parameters of their receiver, everything is transparent and fluid. In a few moments, the stream of corrections then comes from the backup server.

Here is the DNS address used for your equipment:

• DNS Spider Leica Platform: ntrip.reseau-orpheon.fr

Important :
Since January 2017 you can find this information on your delivery note with all the connection parameters

Note :

Customers who decide to keep fixed IP addresses will not be able to automatically switch to the backup system in the event of maintenance or a problem on the main servers. We therefore strongly advise not to keep fixed IP addresses. In addition, we decline all responsibility in the event that a customer has kept an IP address in the configuration of his equipment and if he is unable to connect to our services.

In case your equipment does not accept a DNS address (very rare) here is the IP address: 69.64.185.131 – Warning: the use of this fixed IP address does not allow you to benefit from the automatic failover on the server of rescue.

Find below the various information for setting up the APNs, identifiers and passwords so that your equipment can connect to the internet using the SFR or Orange SIM card that you ordered from Géodata Diffusion.

Enter these parameters in your equipment in the communication part (GSM-GPRS refer to the technical documentation of your equipment).

You will then have to configure the parameters for the connection to the Orpheon network with your username and password (see delivery note)

Discover : Choice of SIM cards

Below you will find information that we think will be useful for the use of the SIM cards of the various operators that we supply.

Important: depending on the type of card or the age of the contract, the Roaming option must be activated

For many years at Geodata Diffusion we have been providing our customers with SIM cards. Since then, the legislation and invoicing rules for the Roaming Europe option have changed a great deal. Some of the cards delivered before these changes did not have the Europe option activated because at the time this option was chargeable and led to significant additional costs for exceeding the package. Today these options have become free and no longer generate unpleasant surprises.

In general, roaming at national rates, which allows you to use your mobile plan from abroad without being surcharged, only applies to occasional use. Your consumption from France must be the majority.

Could I use my mobile Internet volume in the European zone?

You can use your monthly mobile Internet volume both in the European zone and in mainland France(1).
For example, if your package includes 5 GB of internet and you use 2 GB while working in Germany, you will have 3 GB of your package left when you return to France. If your mobile Internet volume runs out, one of the following pricing conditions will apply until the date your plan is reset (depending on the mobile offer you have):
– reduced flow,
– blocking your blocked mobile internet,
– off-package at the rate applicable in mainland France.

Access to the Orpheon network

It should also be noted that mobile Internet access abroad does not systematically give access to the Orphéon network. For this, reference should be made to the network coverage area (Metropolitan France and the West Indies).

To simplify, the Roaming Europe option is mainly useful for our customers working on the edge of borders, when their equipment “terminal” on a relay in the neighboring country. For remote countries, it will be necessary to take out an RTK subscription in the country concerned (example in England, Poland, etc.). We also recommend that you take out an RTK SmartNet subscription.

For Orange SIM cards:

Since October 1, 2019, automatically and without changing the offer: you have nothing to do!

These changes apply automatically and free of charge to your package.

New RTMC-3 MSM data format

Message formats were previously limited to the L1 and L2 bands and a single signal per band, which is why it became necessary to use a new universal real-time data format: the MSM (for Multiple Signal Message) which is the new concept of RTCM-3 key allowing to present all GNSS observation data in generic form.

The RTCM-3 MSM standard thus ensures data interoperability with all compatible GNSS receivers by transmitting standardized observations of GPS + Glonass + Galileo + Beidou signals for all L1/L2 and L5 frequencies.

Antenna and Computing Engine

To be able to use the signals from the different constellations, the receiving antenna and the calculation engine must each be compatible with these GPS, Glonass, Galileo and Beidou constellations in order to be able to take their signals into account to deliver a position.

Multi-frequency L1/L2 and L5

Based on the L1 and L5 frequencies emitted by the satellites in order to make positioning more resistant to interference and signal reflections, especially in an urban environment.

Options and Licenses

Many equipment of all brands today are compatible with all of these signals, options and licenses can be acquired and activated to be able to use them. It is often possible to activate these options and licenses to upgrade your equipment now and benefit from the best positioning services.

Depending on your specialty, contact your usual distributor without hesitation (Find your Orpheon distributor), he will know, better than anyone, how to answer you and support you in your projects.

The calculation is done in the network and is not dependent on a station. The service therefore continues to operate and to provide reliable data. To simplify, when a station is temporarily deactivated (for maintenance or for breakdown), the calculation system replaces it with another, located in the same area. permanent stations Orphéon has been designed in such a way that several stations can always take over from a deactivated station.

The geometric regularity of our layouts

The Orphéon network has 215 stations in mainland France, all Full GNSS, i.e.: GPS, GLONASS, Galileo and BeiDou, as well as a historical presence in the French West Indies.

The dense network of permanent stations is arranged regularly every 60 km. Each link in the Orphéon infrastructure has been designed to offer a high-precision RTK correction service available in all circumstances. Border areas are complemented by our partnership agreements within Europe.

• A very regular presence, without compromise and without equivalent in France.

• The careful choice of layout for each of our 195 reference stations creates a linear and regular geometric mesh. Territory coverage is uniform wherever you are.With the Orphéon network, you work with identical precision throughout the territory thanks to a uniform distribution of stations over all the areas covered, whatever your position, the distance from the nearest reference station is never more than 30 km.The Orphéon network thus stands out significantly from its competitors who are multiplying the number of reference stations because of their disorderly location on the territory and whose coverage is losing homogeneity, sometimes leaving very large distances in the meshes of their network.
• 

  A regular and homogeneous layout

Coverage area

The position of the mobile GPS sent to the server must imperatively be located in the network coverage area but also in the restricted area stipulated when subscribing to the service.

Outside the coverage area of ​​the Orpheon network, the server is not able to provide the corresponding corrections. Our coverage area is defined by the position of our permanent observation stations.

Pay attention to the geographical restriction of your subscription, the server will end the connection and add an error message to the connection log (see Customer Area)

If the mobile GPS returns a position outside the subscription zone

• National: no restrictions
  Regional: the administrative region stipulated during the subscription (or 4 contiguous departments)
  Departmental: the administrative department stipulated during the subscription

Sending a GGA-type NMEA frame

When connecting, it is important to send a GPGGA-type NMEA frame with the position of the mobile GPS. This position will allow the server to define a cell of several network observation stations around the user and thus be able to provide the corrections corresponding to the position.

Caution: If no frame is sent to the server, the error message No GPGGA message received. Access denied is added to the error log (see Customer area).

Similarly, if the position sent is zero (all zero) the message Currently no data available. No sites and/or clusters defined. is added to the error log (see Customer area).

The real strength of the Orpheon network

The NRTK (Network Real Time Kinematic) comes from the use of several bases of observations connected together in a network to optimize and model the information of corrections on the covered area.

the positioning accuracy does not depend on the distance to the nearest physical network station.
