observations.\r\n\r\nIt is necessary that the equipment making up the infrastructure of the network but also the bases of the permanent stations of the network are all compatible with all of these different constellations of satellites in order to be able to deliver a complete and coherent correction corresponding to the different users in the field.\r\n<h3>Capacity increase<\/h3>\r\n<p style=\"text-align: justify;\">The increase in the number of constellations with the arrival of Galileo and Beidou as well as the growing number of network users require the power and capacities of the NRTIP servers used by the network to be constantly upgraded. By being part of the Hexagon group, the Orph\u00e9on network has adapted and comfortable resources, but also a team of experts dedicated to the supervision and maintenance of the infrastructures to ensure a very high level of availability of the Orph\u00e9on services.<\/p>\r\n\r\n<h2 style=\"text-align: justify;\">Guarantee the availability of the real-time service<\/h2>\r\nTo be able to offer the best rate of availability of data and correction services, we have optimized our infrastructures and implemented leading technical solutions.\r\n\r\nAs corrections are disseminated in real time, it is essential to have better infrastructures that can guarantee all data flows:\r\n<ul>\r\n \t<li style=\"text-align: justify;\">The data streams from our stations to feed the servers<\/li>\r\n \t<li style=\"text-align: justify;\">The incoming and outgoing data flows the positions and corrections of each user<\/li>\r\n<\/ul>\r\nTypically, the user&#8217;s mobile receives at each measurement epoch (typically every second) the individualized &#8220;corrections&#8221; corresponding to its work area, even when it moves.\r\n\r\nThese corrections reach each user continuously via mobile internet with an average delivery time of 750 ms, the standard deviation, i.e. the deviation from the mean for 68% of the corrections sent, also being this order of magnitude.\r\n\r\nIn order to keep the system consistent, there is therefore less than 250ms left for:\r\n<ol>\r\n \t<li style=\"list-style-type: none;\">\r\n<ol>\r\n \t<li style=\"list-style-type: none;\">\r\n<ol>\r\n \t<li>Receive observations from permanent stations on the computer center<\/li>\r\n \t<li>Make them temporally consistent<\/li>\r\n \t<li>Calculate &#8220;corrections&#8221;<\/li>\r\n \t<li>Send &#8220;corrections&#8221; to user<\/li>\r\n<\/ol>\r\n<\/li>\r\n<\/ol>\r\n<\/li>\r\n<\/ol>\r\n<img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/reseau-orpheon.fr\/wp-content\/uploads\/2012\/06\/Gps-Reseau-Orpheon.png\" alt=\"null\" \/>\r\n<h2 style=\"text-align: justify;\">We have therefore chosen a very efficient infrastructure<\/h2>\r\n<blockquote>\r\n<p style=\"text-align: justify;\">The implementation of this telecommunications network guarantees us the lowest possible latencies (data transmission time) between the permanent stations of the entire network and the computing center.<\/p>\r\n\r\n<h3 style=\"text-align: justify;\">Goal: Have the lowest latencies<\/h3>\r\nThis uncompromising choice, in order to put the user&#8217;s mobile in the best possible situation by allowing it to receive as many corrections as possible in the most fluid and continuous way.\r\n\r\nThe load rates of a private network are guaranteed by the telecom operators offering this type of service. Such a network is also much more available than the Internet, the redundancy of the links being provided by the operators in charge of its operation.\r\n<h3 style=\"text-align: justify;\">In the chain of transmission of corrections:<\/h3>\r\n<p style=\"text-align: justify;\">Le lien GPRS entre le GPS et nos serveurs NTRIP permet to route 95% of the corrections with a latency of between 0 and 1.5 seconds, hence the crucial importance of this MPLS-type network in terms of latency. A rover configured in interpolated mode (\u201caccuracy\u201d mode at Leica, \u201cforecast\u201d at Topcon and \u201cLow Latency\u201d at Trimble) can typically last 3 seconds without receiving corrections.<\/p>\r\n\r\n<h3 style=\"text-align: justify;\">Why is an ordinary internet connection not enough?<\/h3>\r\n<p style=\"text-align: justify;\">The Internet is a network that pools resources for all users, on the principle of &#8220;best effort&#8221;, even if the performance deteriorates very sharply. The use of the Internet is therefore not relevant here, insofar as we wish to guarantee and control transmission times (latencies).

Thus, in the event of maintenance or a problem requiring a change of infrastructure, your GNSS equipment will automatically connect to our services.\r\n\r\nThe establishment of the address server (DNS) thus makes it possible to switch when necessary from one platform to another in complete transparency for customers.\r\n\r\n<\/div>\r\n<ul>\r\n \t<li>A DNS address server<\/li>\r\n \t<li>No hardware reconfiguration<\/li>\r\n \t<li>An Orpheon service available immediately on another platform<\/li>\r\n \t<li>A fast, transparent and serene changeover<\/li>\r\n<\/ul>\r\n<\/blockquote>\r\n<h2 style=\"text-align: justify;\">Increased monitoring<\/h2>\r\n<p style=\"text-align: justify;\">The implementation of identical and distant platforms allows us to have homogeneous and standardized installations within the Hexagon group.
