I had a crash, I flew my quad and tried going in to RTL, the quad flipped and crashed, when I replayed the flight in MP I saw a "GPS health" warning, just before going into RTL.
When I came home I connected the APM to the MP (using a 3DR radio), I put the quad outside, and I get my location on the map on the MP and a solid blue led on the board, but I get a warning in the MP saying "PreArm: bad GPS pos", after I arm the quad i get a "bad GPS health" but still I see my location on the MP and I get a solid blue LED and 3D fix
I am using an APM 2.5 with all original parts except the GPS (which I got from HK, link: http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=31135)
Thanks for your help.
I am having similar issue, getting "Bad Health GPS" message in MP.
Did you manage to fix this?
Seems quite a few negative comments accompany the unit. Sometimes with HK you get dodgy quality, perhaps this is an example.
