[aprssig] garmin gps and compass heading

[scott at opentrac.org]

Look for an $HCHDG output... not sure what models support it.
 
I was working on an idea for paintball player tracking that'd have magnetic
compass units on each gun, plus a vibration sensor, so you could record the
time, position, and direction of each shot.  With a Zigbee setup you could
show players moving and shooting on a screen in real time.  Not a big deal
for most commercial fields where everyone's in plain sight, but most people
around here play 'woods ball', where the playing area might be 10 acres of
woods and hills.  Doesn't work too well for spectators.

Does anyone know if the garmin units with compasses output a seperate
compass heading?  Note that the compass heading may be different than the
direction of travel (for example if the unit is held horizontal and moved
backwards or left/right.)  My intent is to have a serial compass that shows
which way the gps unit is oriented.
