 Not sure. Some observations by Liam shows that the sondes appear to
know when they are descending, so it looks like the internal GPS is
working.However, given we're not decoding anything sensible on the
ground, it suggests the telemetry format has changed.  
 I suspect it might be a few days before we have a resolution to this
issue.

   another signal now on 403.0 , still no decodes , perhaps the BOM is
having trouble too.

 So auto_rx is definitely detecting the sonde correctly, but it's not
extracting GPS coords from the sonde telemetry, hence why its timing
out.
 The sonde in the air over Adelaide has serial R0230556, but I can't
get GPS positions out of its telemetry. 
 This is going to take me a little bit to figure out. I'm also just
about to fly out from Horn Island today.

 Just had a quick look at habhub. 
 No sondes on the map in VK at the moment.  
 Also thought it was strange that both Perth and Melbourne set off 3
each yesterday morning. Adelaide set off 2. 
 I didn’t have a launch in the log for last night either.

  Yep there is definitely something broken. Probably GPS rollover
related.
 Will look into it.

 Hi everyone

 fine on an SDR but no-one could decode it. my system would start the
 decode process then time out. Any ideas? mybe the GPS bug has got it
