Title: Gps very slow to acquire a fix SOLVED
Post by: Tony T on July 04, 2024, 12:13:49 pm

For the last few months, the gps in our Rosetta has been taking a long time to acquire a fix.  It used to come up virtually as soon as it turned on but can now take 20 minutes which is not ideal!  The unit has not been moved and only has perspex or thin ply between it and the outside.  It seems to be worse if it has not been used for a week or more.  I wondered if  there was battery back up for the almanac data in the gps that has failed?  Any other suggestions?

Hi Tony,

Most GPS modules do have a small button cell in them to power the almanac memory which is recharged by the circuitry, but they can eventually die. Unfortunately the 'workings' are normally sealed inside a metal screen and the cells are usually spot-welded in to a holder on the board, so not replaceable. If you are having serious issues, it might be worth trying a replacement GPS - available from the PilotAware store.

Regards

Peter
