Here 3 GPS - No fix

Here GPS
1

Hello all,

I am trying to use the Here3 GPS and HEX Cube Orange with Ardupilot (Copter 4.3.1 Official) firmware for my drone but so far I am not getting any signals or 3d Fix from the GPS. I have been using Mission Planner (V1.3.79) as the ground station software. It would be great if I could get assistance in solving the GPS 3D fix issue.

Below are some of the steps I tried until now to get the 3D fix.

  • modified the parameters in Mission Planner (as instructed in the official website)
  • updated Mission Planner and the Here3 GPS (as instructed in the official website)
  • changed the CAN node ID
  • tried to connect to u-center (doesn’t show any satellites though)
  • checked in both inside my house (closed space) and outside (open space)

Please let me know any additional information I need to provide too.

Hi
Did you get 3d fix before on this GPS unit ?
Can you please share your MP HUD ?
What is the LED indication?
Did you try with another CAN port?
Do you have another GPS or FC ?
Can you swap GPS and FC and see if this issue happened again on that GPS or FC?

Hi all, I am also facing the same issue. I am able to see compass of the GPS displayed as UAVCAN with ID as 125. The GPS has no fix even after keeping it outdoors for more than 15 minutes. Number of Sats is 0 and HDOP is displayed as 100. Kindly help me resolve this issue as soon as possible. Thanks in advance.
