FLIGHT EXPERIMENT: Flight Qualification of the "New Flight Controller, Shuttle II"

EXPERIMENT CONDUCTED BY: Jack Crabtree/AA0P and the rest of the gang at EOSS
PROJECT INTEGRATOR:      Jack Crabtree/AA0P
FREQUENCIES:
Shuttle II:
    Telemetry    144.290 MHz (AX.25 Packet - Plain Text)
    ATV          426.250 MHz
Tracking Beacon: 147.555 MHz (CW FM)
HF Net: 7230 kHz LSB + or - QRM
Tracking and Recovery Team: 146.970 MHz Repeater

PURPOSE OF THE FLIGHT:

Flight qualification of the EOSS standard balloon bus, "Shuttle II." Shuttle II consists of an improved balloon controller designed and built by Bob Schellhorn, W6ORE, based on the 80C552 microprocessor chip.

Flight tests of a new Global Positioning System (GPS) system will also be made.

Once qualified, Shuttle II will be pressed into service on future flights involving student designed and built experimental payloads. The W6ORE controller will support a wide variety of experiments limited only by the experimenter's imagination. GPS will provide precise tracking information. This will provide a more accurate data track of the path and altitude of the payload throughout the flight thus offering experimenters more precision in the analysis of their data.

PAYLOAD SYSTEMS:
A five channel Magellan OEM/5V GPS receiver board will provide Altitude, Latitude, Longitude, Course, Speed, Range and Bearing to the Launch Site data on the packet telemetry AX.25 downlink. This is the first flight for the GPS system.

Internal and external temperature and barometric pressure (included as altitude) will be included in the packet telemetry signal. 

An Automatic Position Reporting System (APRS) compatible packet position message will supplement the above information on the telemetry downlink frequency. APRS users in ALL states adjacent to Colorado should "hear" the payload as it approaches maximum altitude.

Amateur Television will be transmitted from the payload. A black and white camera will send down views of the ground, horizon and balloon and parachute.

Hope to see you all at the next flight of EOSS.
