The raw data provided below is in Amateur Radio APRS format.  
The top line (header) provides a timestamp, callsign of the 
transmitting station (N4OSB-11 is the mission callsign), then 
some formatting data describing how the data is to be handled 
when received. The next line is the actual tracking data 
starting with a GPS time stamp (in UTC), Latitude/Longitude, 
the letter "O" which tells APRS tracking applications that it 
is a balloon (many programs even put a balloon icon on the map 
at the position), direction of movement, speed (in MPH), and 
altitude (in feet).  
The data between the "!" marks at the end is extra data in a 
binary format, that we don't use.
