Re: Post Launch Info
- Hi Don,
Dang! Sorry to hear you lost your payload! But if someone did pick
it up, they might be kind enough to get it back to you. I've heard
that some 80% of NWS radiosondes actually get mailed back by folks
who find 'em!
Re the GPS NMEA altitude data: I'm not familiar with the Garmin GPS18lvc,
but the NMEA sentence you want is $GPGGA, which includes MSL altitude
in meters, plus lat/lon, GPS time hhmmss, no. of sats in track and
VDOP. It's really all you need for balloon tracking, although the
$GPRMC sentence also includes GPS date yymmdd, lat/lon, rcvr status and
course/speed - but no altitude.

(Texas Tech ARC) balloon had $$$ rewards written all over the
package. Never put that in use though (recovered all, even the one
that had triple failure, lost the 915 MHz GPS serial link on descent,
lost APRS on ascent, and no backup beacon, after the battery
dislodged during a bumpy take off due to a sideward wind gust).
A side note, we lost the first balloon, when we're still clueless and
didn't put the $$$ sign.
