Hi Joe,
you initially said
Rosetta couldn’t find GPS until back East of Malvern.
Can you provide the exact wording of the error that you saw ?
I suspect that SD was not reporting a GPS error, but was more likely reporting cannot connect to device ?
I can see no loss of GPS in any of the data, however the data is truncated into 3 files
This indicates a catastrophic fail - most likely a power disconnect, and this would explain why there are 3 files as the system rebooted when power is lost
it is not possible to definitively prove this because of course, if the power is lost no writes to the log are made.
Categorically there are no GPS issues, the lock was constant for the entire time the unit was running
can you check the cabling and importantly if any of the connectors feel a little loose.
Thx
Lee
