Loki: Troubleshooting GNSS LED not turning green


Loki’s GNSS LED isn’t turning green. (The GNSS LED is the one on left above the USB C port)

Probable Solution:

A green GNSS LED on Loki indicates that it has good reception.  A red GNSS LED can be caused by a number of things.  The following are suggestions if you are having trouble getting the GNSS LED to turn green:

  1. Time: Loki takes time to get a satellite lock and will remain red until it does get a lock.  Depending on the situation, Loki may need a few minutes to turn green.
  2. Obstruction: Loki needs a clear view of the sky to see the satellites.  Move to a more open area, away from large objects.
  3. Connection: Make sure the Loki antenna cable is properly screwed in and that the antenna is properly screwed on.  Power Loki off, remove the antenna and antenna extension cable.  Then put the antenna and extension cable back on the Loki, making sure to properly thread it when screwing the items together.  Also make sure the brass fitting on the antenna ground plane is tight, if its loose tighten with a 5/16″ driver. Then, power the Loki on again and wait for the GNSS LED to turn green.  If this does not solve the problem, try taking the Loki off the drone and screw the antenna directly on to the Loki.  Then, place the Loki in an area with a clear view of the sky, the LED should turn green.  This will narrow down the issue to see if its a problem with the extension and or fittings.
