Loki did not record an SBF file

Problem:

I performed a flight, but the SBF file does not show up on Loki when I connect to download the file.

Probable Resolution #1:

The disk space on Loki is full and the SBF file was not written to Loki’s external drive. Delete some older files, power on Loki, and check to see if the missing file(s) are present.

Probable Resolution #2

The GNSS light never turned green and the SBF file was never created. The GNSS light on Loki will turn green when two conditions are met:

1. A valid date/time stamp was received from a GNSS satellite.
2. The SBF file was created.

Also check the GNSS antenna and cable for damage.
