Hello,
Most of GPS chip used in RC is the UBlox. The design of this chip is about 10 years old, and I use the NV08C since 4 years; which I think perform best and also receive the GLONASS Russian GPS information (see picture).
I also put a saw filter to reject all out of frequency pollution signals and an active GPS patch antenna.
I wonder if someone has already written a algorithm to combine all GPS information, including the gyro, sensors and compass information, in order to obtain a position of less than 50cm 3D precision, including for inside use….
If not, maybe someone interrested collaborating on this project as open source?
Regards
Domy
