The DMSP program designs, builds, launches, and maintains several near polar orbiting, sun synchronous satellites monitoring the meteorological, oceanographic, and solar-terrestrial physics environments.

DMSP satellites are in a near polar, sun synchronous orbit approximately 830 kilometers above the earth. Each satellite crosses any point on the earth twice a day and has an orbital period of about 101 minutes, thus providing complete global coverage every six hours. Each DMSP satellite monitors the atmospheric, oceanographic and solar-geophysical environment of the Earth.
