- - Spacecraft Brief Description - The Japanese Marine Observation Satellite-1b (MOS-1b) was the second Earth resources satellite in the MOS series to be launched by NASDA to monitor atmospheric water vapor, ocean currents, sea surface temperature, ice floe dynamics, chlorophyll concentration in the oceans, and vegetation and agricultural land applications. The MOS-1b carried the same three sensors as the MOS-1a: a Multi-spectrum Electronic Self-Scanning Radiometer (MESSR), a Visible and Thermal Infrared Radiometer (VTIR), and a Microwave Scanning Radiometer (MSR). Data was transmitted real-time to the Hatoyama Earth Observation Center for processing and is available through the Data Service Department, Remote Sensing Technology Center of Japan (RESTEC). The satellite also included a Data Collection System (DCS) Transponder designed to be a forerunner of the Japanese TDRSS, used to collect and relay information from surface Data Collection Platforms (DCPs) and locate DCPs based on the Doppler frequency of received signals. The satellite is a 1.26 x 1.48 x 2.4 meter high box-shape of aluminium honeycomb construction with a single solar array of three 1.51 meter wide panels. The satellite is controlled in three axes by momentum wheels and four IN hydrazine thrusters. Other MOS satellites are planned throughout the 1990's.
