James Magos replied to James Magos's discussion Checking mediatek's APM 2.0 On board GPS health"ok, i re measured voltages from traces 1 & 3 on mediatek with an accurate voltage meter, resulted in 3.31v constant, so power shouldn't be an issue.

Hello everyone, All of you having an older APM, should know how to test, or update the firmware of your uBlox, MediaTek GPS, witch is the right way to test our new daughter board GPS, or refirm it, if:- blue led keeps blinging- measuring voltage on traces 1 with 3 or 8 gives ~3.12v - doing a CLI test responds to Lat : 0 Lon: 0 Alt: 127m,…See More
James Magos replied to Richard's discussion First APM2 Build for Aerial Photography to create DEM,DSM for GIS purposes - Ursus Airframe"your welcome!!
I have tried setting a 1/4000th shutter speed, but the camera seems to only take a maximum of 1/1500th.
Men! thats near sun exposure!! I think the optimum for 80is is 1/400 and still will be darky.. so try 2 or 3 factor with…"

James Magos replied to Richard's discussion First APM2 Build for Aerial Photography to create DEM,DSM for GIS purposes - Ursus Airframe"Good morning Richard,
the factor 4 * 1/1000 gives you shutter speed 1/250 which is a bit low, but i didnt new your area solar radiation also i didnt gave attention to your camera model (80is), ND filter doesnt make any difference fo…"

-value factor = 1/1000

Hi everyone,
For years now we use model aircrafts as a hobby or job, and for many years as aerial platforms for aerial photography and mapping.
