\n\t\t\t\t\t\t\t\t\tWe receive many requests concerning the operating principle of RTK corrections but also many questions about the possibilities of integrating a GPS chip to develop its own applications.\r\n\r\nWhat could be simpler to answer these questions than to go through the same integration steps to better understand the operating logic.\r\n

Democratization of technology<\/h2>\r\nToday the integration of precision GNSS chips is democratizing by becoming affordable and makes it easy to imagine all kinds of practical uses. It then becomes possible to integrate an RTK receiver with centimetric precision in a compact, light and energy-efficient design to meet the requirements of these new applications and thus free the imagination and creativity.\r\n\r\n\"null\"\r\n

Objective of this test<\/h2>\r\nOur goal here is not to promote one product over another, but just to use a module that will simplify our access to a centimeter position given the little time we can devote to this exercise.\r\n\r\nOur objective is quite minimalist since we just want to be able to connect to the Orpheon network server and obtain the corrections to display a position whose precision has been increased thanks to the network corrections.\r\n

Warnings<\/h3>\r\n

This test makes it possible to illustrate the stages of integration in an attempt to popularize the main lines of the content. There is no question here of worrying about performance or precision (maybe we will do that later). There is also no question of providing a turnkey solution or software or part of a program.<\/p>\r\n\r\n

There are several evaluation kits on the market:<\/h2>\r\n

On our side we tested the Sparkfun ZED-F9P circuit because the implementation is quite simple. Ordered more than a year ago, we cannot tell you today how soon or at what price this devaluation kit is now available.\r\nTo do the very first tests very quickly, it is possible to connect a PC via its USB-C port (which will power the card) and a GPS antenna, for our part we have opted for an AS10 Leica antenna available on our shelves .<\/p>\r\n\r\n
