dual heading with arduino mega - first test
Conntections:
Arduino Mega < rxtx1 / rxtx1 > UBLOX F9 (A)
Agopen < USB > Arduino Mega F9 sends Nmea via Mega to Agopen / Agopen sends rtcm via Mega to F9
UBLOX F9 (A) < xbee tx to xbee rx > F9 (B) first F9 which is the RTK Receiver sends his own rtcm to F9 (B)
F9 (B) caculates Heading und Length and hight difference to F9 (A) and provides Relposned (UBX)
F9(B) < tx1 to rx2 > arduino Meaga Mega parses to UBX Protocoll, calculetes roll and sends nema hdt (heading) and avr (roll) to agopen via usb port
