Unable to upload flight: "Invalid location data was found in that log, ignoring" #133

Closed hsteinhaus closed 9 years ago

The flight itself looks pretty normal in mavflightview, LogAnalyser has some (justified) warnings, but not regarding GPS, no ERRs in log. Here is the file: https://www.dropbox.com/s/7sqh24v7h2p8a3s/iris-uavcan-tridge-350.BIN?dl=0

Note: I am testing a new kind of GNSS module currently in this copter - so it is well possible that something here is different than usual.

thanks for the report - I'll take a look later today.

The problem was that the first GPS message had a very bogus time (somewhere in the year 2400s). I'm changing the server to throw out such values.

Thanks for the info about the wrong time info in the first message after fix. I will try to find out where it comes from.

Can confirm that it works now, the file with invalid time uploads without any trouble. In between, I fixed the reason for the wrong timestamps in APM as well: https://github.com/diydrones/ardupilot/pull/1642-
