Garrecht Avioncs seems to have source code for the GPS module, and
intends to provide a fix in that code for their Volksloggers. It should
be straightforward to add another 20 years of life that way.

Hi All,

1)
yes, we probably have a fix for the GPS25 modules, but it has to be confirmed working under all circumstances by a GPS simulator. This will of course take some time ...

2)
We do NOT have the sourcecode ...

3)
The only two solutions Garmin has officially suggested to us a

a) recharge the battery for 2 days and reinitialize the module by it's serial interface to a new date = obviously this only works for another 2-5 months.

Also, the rechargeable batteries inside the GPS25 also age with time - Garmin should know this. We got lots of new modules at beginning of the 2000s which were not able to hold their time and date for even 2 weeks.

b) replace module by GPS15 module.

For technical reasons, both solutions are not an option for us, thus we'll continue work on the firmware-patch, and at the same time on a software-only solution (new VALI-GCS files, maybe new VL firmware).



Good luck with the CAI solution.
