Using more than 1 F9P on board

[agrotronic]

I have seen some guys posting boards with 2 F9P and also with 3 F9P.

Just wondering what is the reason of that? does it make fFix Position more accurate?

with 2 RTK receivers, you can calculate the orientation of the tractor (heading, roll, etc)

any documents or website I can get information about it?

Dual GPS setups

Split from this topic: Front to BAck Dual Antenna - #82 by kareldew. The idea is you can share experiences and hardware setup for the dual GPS code from Matthias here: GitHub - mtz8302/AOG_GPS_ESP32: DUAL or SINGLE GPS bridge between AgOpenGPS an GPS receiver. Works with 2 UBlox to calculate heading+roll. Corrects and filters. ESP32 + Arduino MEGA Here is my rough test setup with the ESPduino, I had no problems, just had to switch the two F9P’s in place again (my bad). Roll, heading very accur…

Dual GPS output format for AOG

I am using a dual ardusimple gps plus a radio on a purpose build small rover. I use a third gps for the base. This set up provides a rtk position and heading. The heading is not affected by metal or magnetic objects like most magnetometers are. The dual gps heading device is working well and I want to try it on the AOG code. our system outputs a GGA message for position and a POLYA message for the heading. To be compatible with AOG what format is required? I may also use a Tinkerforge Brick …
