Significant solar activity every 11 years

Solar activity follows an eleven-year cycle, with 2015 being a maximum of this cycle. This year 2020 is therefore synonymous with the end of a cycle of reduced ionospheric disturbances for our applications. We must expect in the future to have to deal with increasing solar activity, hence the importance of having a dense network of permanent GNSS stations to properly model this error. As you can see in the graph below, the cycle of solar activity is reaching its minimum and the forecast for this activity is now on the rise:
Le cycle de l'activité solaire de 2002 à aujourd'hui
The cycle of solar activity from 2002 to todayDuring a day, ionospheric activity related to solar activity peaks around 12:00 p.m. solar time. Thus, as shown in the graph below, this ionospheric activity was very high on Wednesday October 2 at noon with I95 index values ​​beyond the limit of 8 indicating very high activity for the targeted applications and therefore impacting all communications satellites during their passage in the ionosphere then rich in charged particles:
Activité ionosphérique
Ionospheric activity

Disturbances related to geomagnetic storms

As you can see on the SpaceWeatherLive.com website, this phenomenon is global with an ionospheric index K (quantification of geomagnetic disturbances). This is an average of the K indices relating to 13 stations located between 44 and 60◦ latitude; it is therefore an overall index. Activité ionosphérique The K index is a local index which characterizes the variation of the magnetic field at the station considered compared to a calm reference day; these measurements are made using magnetometers. The Kp index scale includes 10 rungs: null

The impact on your connection

As you will have understood on this subject, if you have problems in the middle of the day (abnormally long time to fix the entire ambiguities or impossibility of fixing them in clear environments, repeated passages while floating even though you receive many corrections, etc. .), check the number and distribution of GPS satellites and check ionospheric activity via the site: http://gpsweather.meteo.be/geomagnetism/ground_K_dourbes. null

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.

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. null

As a reminder, in order to be able to position itself within a few centimeters, a GPS/GNSS rover must be able to:

  • perform noise-free phase measurements on at least 5 satellites well distributed in space,
  • and receive differential corrections on these same 5 satellites.
Adding 2 constellations of additional Galileo and BeiDou satellites to those of the GPS and Glonass constellation thus makes it possible to increase the possibility of receiving a sufficient number of signals and of better quality, especially in difficult places. Indeed, in an urban environment, the walls of buildings or trees create masks which limit the number of visible satellites but also create “echoes” (multipath) which disturb the calculation of the positioning of the equipment. The number of visible satellites has therefore always been an important issue for quality positioning.

How does it benefit you on a daily basis?

100% more satellites

The addition of the Galileo and BeiDou satellites to the GPS and GLONASS satellites significantly increases the number of satellites that can be observed simultaneously by a GNSS antenna. The addition of the GALILEO and BeiDou constellations thanks to the Orphéon network is not a simple gadget, but the assurance of better daily productivity in the field. Indeed, you can now permanently count on the constant availability of at least 6 additional satellites to bring you real advantages:

Improved positioning quality

  • More satellites available to calculate its position
  • Precise positioning even in difficult environments (urban canyons for example or under a canopy)
  • Improved positioning reliability
  • Shorter fixing time

Note: a terminated account can still access its customer area and can thus still access the corresponding invoices on the one hand, but also if this account is the oldest, it remains the supervisor and still allows all invoices to be viewed. of your other subscriptions.

At Geodata Diffusion:

Our invoices are created automatically, sent, received and stored in electronic format (PDF) by our integrated management software package system, under the legal conditions in force. The result of this digitization is the true copy of the original, identical to the invoices that we previously produced in paper format.

GPRS Option: Mobile Internet

Offer reserved for professionals subscribed to GPS corrections. In order to receive your positioning data via mobile Internet (GPRS), your GPS receiver must be equipped with an active SIM card from a mobile telephone operator. If you don’t already have one, it will be essential to equip yourself with one. We wanted this point not to penalize your budget, and have therefore developed strong partnerships with the French mobile telephone operators Orange and SFR. Thus, we offer with all our subscriptions, the SIM card at an exceptional price.

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 :

This site will allow you to determine the quality of coverage of an area depending on the operator selected. The area can be searched by municipality. It also helps to determine which operator best covers the area.

2/ the ANFR website

This site allows you to view the location of the relay antennas of the telephone operators (among others) Which can allow you to determine more precisely the quality of coverage of an area depending on the selected operator and the distance with the ‘cell tower. The area can be searched by municipality.

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.

Sending a GPGGA-type NMEA frame

When connecting, it is important to send a GGA-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).

Content of the NMEA GGA frame

There are a large number of different NMEA frames, more than thirty. These frames are defined by the NMEA 0183 standard which is a specification for communication between marine equipment, including GPS. This standard uses frames or sentences to transmit information, each information is separated by a comma.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
$GNGGA, 073939.00, 4841.47953, N 00212.97078, E, 1, 24, 0.62, 165.7, M, 46.2, M , , *42
The frame begins with the sign “$” then the type of epic is defined by the two characters that follow. Each frame has its own syntax, but depending on the case, they must end, after the “*” sign, with control bits which make it possible to verify that the frame has not been damaged before its reception. The NTRIP server needs the information contained in the GGA frame because this frame provides the current position of the GPS receiver. NMEA frames all refer to the WGS84 ellipsoid as the base coordinate system. null
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).

When connecting, it is important to send a GGA-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.

Maintaining connection with the server

Caution: To maintain the active connection between the GPS receiver and the Ntrip server which sends the corrections, a GGA frame (if possible updated with the real position of the GPS) must be sent regularly to the server. This measurement helps ensure that the link is truly up. If after 30 seconds no GGA frame is sent to the server, the latter considers that the link is interrupted and terminates the connection. In the error log (see Customer area) a new information message indicates: Rover user rejected. No heartbeat received.

Connection to the Orpheon server via an NTRIP Client app

It is possible to connect a precision GPS module (RTK) via the USB port to a PC For this, there are several possibilities to connect to the Orpheon server to receive the corrections necessary to increase the precision of a GPS-RTK. As long as the GPS is not connected and does not receive RTCM correction messages from the Orpheon server, this GPS works like an ordinary GPS with an accuracy of several meters (natural mode). Apps The applications presented here are given by way of example because free provided by a manufacturer or available on the internet in open source.

As a reminder, in order to be able to position itself within a few centimeters, a GPS/GNSS rover must be able to:
  • perform noise-free phase measurements on at least 5 satellites well distributed in space,
  • and receive differential corrections on these same 5 satellites.
Adding the constellation of Glonass satellites to those of the GPS constellation thus increases the possibility of receiving a sufficient number of signals of better quality. Thus, the productivity gains linked to the use of the constellation of GLONASS satellites can be estimated at +20 to +30% in semi-urban areas or near trees. Learn more:

RTK

RTK (Real Time Kinematic) is a device for transmitting correction data from an observation base to mobile GPS in real time. The mobile will then integrate this information into its positioning calculation to gain precision. The NRTK (Network Real Time Kinematic) comes from the use of several bases of observations to optimize and model the information of corrections on the covered area. The data from this network of observation stations is collected in real time on a centralized server. Mobiles connect to the server via mobile internet to get their corrections information.
