Sven (DL7AD) hasimproved the LPC1114 version of the Pecan Pico 6 software. He implemented a Unix like UTC timestamp and cleaned up the GPS coordinate calculations. He has found (and fixed) a bug that arbiarily changed the transmit frequency of the tracker due to false coordinates and the resulting impacts on geofencing. However he introduced a new bug where the APRS timestamp is falsely created when the Unix time crosses UTC midnight.
We’ve launched a floater yesterday evening. The solar powered tracker works fine and transmits positions and telemetry. However the timestamp is corrupt, which causes APRS.fi to reject all position packets. This makes tracking difficult, but we’ve found a couple of workarounds, how DL7AD-11 can be tracked for now:
