We have a couple of questions regarding the use of our Sirius Rover and base station.
Is there some detailed documentation on how RTK works and how the rtcm messages are processed in the rover.
We use the rover and base station in combination with a pixhawk4 running px4 and qgroundcontrol. What we see is that the gps coordinates when flying are within the lock-in radius of 0.6 meter that we use in our test. However before the flight when the drone is stationary on the ground, and when the drone is done with its mission and hovering, we see a lot of drift and the gps coordinates are often outside the 0.6m boundary. Why is this and is there something we can do to prevent this? For an example of this behaviour click here
A. In the end we want to fly with a higher precision of about 0.2 meters. What are the things we can do to speed up the lockin, or is there a way to find the location of the base station within this accuracy with the Drotek software, and how can this be achieved?
B. An alternative option for us would be to fly relative to the base station. Is this possible and if so what changes need to be made to set it up?
