Marine Observation Satellite-1 (MOS-1), also known as Momo-1, was Japan's first Earth observation satellite. It was launched on 19 February 1987 on a N-II rocket from Tanegashima Space Center and was operated by the National Space Development Agency of Japan (NASDA). It is in a polar orbit at roughly 900 km altitude, but was decommissioned on 29 November 1995.
Instruments
It has four instruments:
- "Multi-Spectral Electronic Self-Scanning Radiometer (MESSR)" which offers 50 m resolution in two visible and two infra-red spectral bands over two 100 km swathes.
- "Visible and Thermal Infrared Radiometer (VTIR)" which has a much lower resolution in one visible and three infrared bands over a 1,500 km swathe.
- "Micro Scanning Radiometer (MSR)" which measures microwave emission in the 23 GHz and 31 GHz bands.
- "Data Collection System (DCS)" which is an experimental transponder.[7]
