Data Collection System Transponder (DCS Transponder)

NSSDCA ID: 1987-018A-04

Mission Name: MOS 1
Principal Investigator:


The experimental Data Collection System (DCS) Transponder was used to locate Data Collection Platform (DCPs) such as drifting buoys. Observational data from DCPs were transmitted at 400 MHz to a down-converter in the transponder, and the output signal is then transmitted with phase modulation by a 1700-MHz link to the Earth Observation Station in Japan.
