Development of Marine Observation Satellite-1

The program of MOS-1, the first Japanese earth observation satellite system to be developed for experimental purposes, is outlined. The mission objectives are to establish fundamental technologies common to both marine and land observation satellites, observe the sea surface and atmosphere using visible, infrared, and microwave radiometers, and verify the performance of these sensors. A table giving the characteristics of the MOS-1 sensors is included, and the data collection system transponder is described. Also included is a schematic diagram of the MOS-1 communication system. The various systems making up the ground segment are also described.
