Ozonesonde Hitchiker 06/06/2009

- Huntsville AL (NSSTC building)

Stephanie Long prepares to launch the weekly ozonesonde

Liftoff - ozonesonde in the middle - 2m GPS tracker below that

Landing site about 500 feet south of the Tennessee River just south of the Redstone Arsenal

Ozonesonde and 2m tracker in the field - swampy area in the background

Data reception by the 2m GPS tracker (last part of flight):

This was a test of various weak signal modes for low power telemetry - The DominoEX MFSK modes performed the best...some of the DominoEX data is shown below...the new low power Inventek GPS receiver performed flawlessly even during the rapid spinning during descent....6 to 10 satellites were tracked throughout the flight.

The balloon was clearly visible when above 80,000 feet and I had a nice visual of the burst through binoculars...could actually see the orange parachute while at 32 km altitude.
