I can't locate the chat transcript, but the support person specifically said that a GPS status of BAD was due to Mimosa disabling the GPS radio in the current firmware.
I told the Mimosa support person that it's GOOD on our A5c radios and they told me that while the GPS is disabled in the A5-14, it is active in the A5c.
The A5-14 in question has a clear view of the sky and the only other radio on the tower is a B5 10' below the A5-14.
You may want to look back at my support chat history and find out where we went off the rails. The person was very specific that my GPS would come back to life with the next firmware update.
