The thing that attracted me was the fact that the RTK processing is done right on the GPS. Others have done it with raspberry pi talking to a receiver that can output carrier phase information and you can do it that way for less money but it gets a bit bulky for a model aircraft.

My onboard GPS needed often a long period of time until it had a GPS fix, yesterday it did not work for 35 min. After a hint from another user i tried to shield the GPS from RX. Indeed it fixed within 20s. The STM32F103 cpu frequency 72MHz shall be the culprit?

My final solution is a pcb connected to RX GND between RX and GPS. The GPS fix is now always reached within 30s.

oXs GPS under MPX M-Link with FrSky converter on Taranis.

Tested today. Working fine.

oXs #1 with MS5611, ACS712 and voltage divider for Lipo voltage
oXs #2 for ublox Neo7M

See some pics here -> http://www.rc-network.de/forum/showthre ... ost4309441

COURSE and BEARING instead of NMEA coordinates is a thing, you have to get used to ;)
