[OZAPRS] PICO balloon flight Melbourne - Sydney with APRS payload

[Andy Nguyen]

Hi Gary,

The last high altitude reading (21k) was just a glitch in the GPS receiver. It appears to be a known problem when that brand of receiver is switched off and on.
We have another direct packet received by VK2HAB on the coast after that (49.5km away) and it showed the balloon maintained altitude, ie. it didn’t burst at that point.

Regards
Andy
