Here3+ GPS No Fix Issue - Need Assistance

Hello,

I am experiencing an issue with my Here3+ GNSS module where it fails to obtain a fix despite being outdoors with a clear view of the sky. I have already ensured that my firmware is up to date, and I have taken several troubleshooting steps, including:

  1. Verified all connections are secure and undamaged.
  2. Confirmed the GPS configuration in the flight controller software (Mission Planner/QGroundControl) is correct.
  3. Tried connecting the GPS module to a different port on the flight controller.
  4. Ensured there are no sources of RF interference nearby.
  5. Performed a fresh compass calibration.
  6. Verified that the GPS antenna is not damaged and properly connected.

Despite these efforts, the GPS module still does not obtain a fix.
Here are some additional details:

  • Model: Here3+
  • Flight Controller: [cube orange plus with arducopter 4.5.4 firmware]
    Thank you in advance for your help!

Best regards,
