Hi, this is my first APM quad copter.
I followed the wizard and wiki docs to complete all setup/calibration of the quad copter. This includes calibrating the radio, compass and accelerometer. I also did the motor setup to get the throttle ranges and number of cells i have in my battery.
The only problem is that I didnt buy a GPS, I was originally planning to first get the quad setup and then test it without GPS first. Then add the GPS later. However, whenever I try to arm the motors, it would fail. When I checked the HUD on Mission Planner, all it says is DISARMED, GPS: NO GPS (in lower right).
I have disabled GPS heading as well as geofencing. I have even tried disabling prearm checks altogether via the Arming Check (under standard params) and verified in the full parameter list that the value is set to zero.
I still am unable to arm the quadcopter. My qtn is, does APM “REQUIRE” a GPS to operate? And if it doesn’t how can I arm and fly the quadcopter? I tried searching on google and looking through various resources but to no avail…
Any help would be greatly appreciated.
Thanks!
