No more blue light on APM or GPS Ublox

Posted by Drone-University.com on April 2, 2014 at 2:36am

Ublox 3DR

No more GPS fix, bad GPS health on MP, compass working OK.

Power on Ublox says 4,87v when connected to USB and 4,95v when connected to Lipo

I have the jumper off and a 5V bec on the outputs, everything worked fine until now.

I suspect some cable / connection issue.

What is the exact voltage mean to go to the GPS please ?

Thank you

    Well I am underpowered, not overpowered

    Here is a chart. It looks like I am losing all sats, then it comes back. Cable issue ?

      Can you add the HW Voltage to that chart?

    I had the same issue, it turned out that my BEC supplying 5.5v was actually supplying 6v..

    In your APM Planner, there is a parameter that shows you the HW voltage, it should be less than 5.4v. If it's more, I think there is just a resistor so the voltage goes up to the GPS..
