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…

To be compatible with AOG what format is required? I may also use a Tinkerforge Brick …
