DROTEK L1 RTK GNSS compatible PIXHAWK (Ardupilot/PX4) 

Drotek, French tech start-up is proud to release its L1 RTK GPS !
RTK technology allows to enhance GNSS positioning and to go down to centimeter level precision.
It has been used for a long time by surveyors, but at a very high cost. Today we want to trivialize this technology.
In this test, we modified an Iris+ drone, removed its GPS and replaced it by our board. Take-off is manual, and as soon as the drone lifted we triggered Return To Launch mode. The drone succeeded in landing on the table approximately 1 out of 2 times. It touched the table with at least two feet each time we tried the procedure. Wind conditions were quite gentle but with a fair amount of gusts. Even if the board provides precision, there has been a lot of work on the controller’s PIDs to achieve this result!
We used a Netgear WiFi router to transmit raw data from the base to the rover, using Edison's WiFi. Base was connected in Ethernet to the router, everything powered by a 4S LiPo and a 12V power module.
