American earth weather satellite. DMSP 5D-2 was the military's sixth generation of weather satellites. Meteorology satellite built by RCA Astro → GE Astro → Martin Marietta → Lockheed Martin Astro, USA. Launched 1982 - 1997. Used the TIROS-N Bus bus.

AKA: Defense Meteorological Satellite Program. Status: Operational 1982. First Launch: 1982-12-21. Last Launch: 1997-04-04. Number: 9 . Gross mass: 770 kg (1,690 lb). Height: 3.40 m (11.10 ft).

The DMSP 5D-2 satellites operated in two-satellite constellations to provide world-wide meteorological, oceanographic and solar-terrestrial physics measurements on a twice-daily basis. The visible and infrared sensors collected images of global cloud distribution across a 3,000 km swath during both daytime and night time conditions.

The coverage of the microwave imager and sounders were one-half the visible and infrared sensors coverage, covering the polar regions above 60 deg on a twice-daily basis, but the equatorial region on a daily basis. The space environmental sensors recorded along-track plasma densities, velocities, composition and drifts. The spacecraft was based on the GE Tiros bus and 3-axis stabilized using reaction wheels and torque rods to within 0.01 deg. The hydrazine propulsion system was used for orbit insertion, a nitrogen propulsion system for stationkeeping. Star sensors and gyros provided 0.01 deg. knowledge. An Earth sensor and sun were sensor carried as backups. Data was stored on a tape recorder. The solar array generated 900 W (BOL) and recharged NiCd batteries with 30 AHr capacity. S-band communications were via 5 W RF, 5 MHz bandwidth, omni antennas. The satellites were controlled from Offutt AFB, Nebraska with terminals at Loring AFB, Maine; Fairchild AFB, Washington; and AFRTS Hawaii. The payload mass of 110 kg, included:

  • Operational Linescan System (OLS) - visible/infrared imager
  • SSM/T - atmospheric sounder producing cloud temperature profiles
  • SSM/I - microwave imager measuring ice coverage, precipitation areas and intensities, cloud water content, ocean surface wind speeds
  • SSB/X2 - gamma and x-ray spectrometer
  • SSJ/4 - measured proton and electron densities
  • SSM - magnetometer.

The R&D cost for DMSP 5D-2 was $ 7.6 million. The first joined 5 earlier generation DMSP's still operating in orbit. Launch of 8 more continued through 1997.
