I've recently purchased an APM2 with a builtin GPS. It is mounted in a HK Turnigy Talon v2 quadcopter. I've had a few flight in stabilize mode and it works well but I cannot get a GPS fix. The blue leds on the dautherboard and on the main board are both blinking. I have currently no telemetry but when I connect with an USB cable to a laptop and getting outside, I can see in MissionPlanner that it sometimes gets 1 sat and very rarely 2. I tried for tens of minutes (maybe 30 or more minutes) without a better result. I get no GPS fix neither with the APM being powered by a lipo nor by the USB cable. I've tried in different locations with no better results. My car's GPS in the same locations gets a GPS lock in one minute.
What could I do ?
Here ya go... what you want. just de-activate the on board GPS, and connect this bad boy up. it has a bigger antenna surface area, and the reviews are incredible. you could extend its height over your gear with a light rod. https://store.diydrones.com/3DR_GPS_LEA_6_p/br-3drlea-6.htm
I would also like to change the mediatek for a uBlox LEA-6. I have the APM2.0 with built in MTK.
How do I de-activate the mediatek, do I have to unsolder it from the board or can I leave it in?
