Defense Meteorological Satellite Program (DMSP)
Provide global visible and infrared cloud cover imagery and other atmospheric, oceanographic, land surface, and space environment data to support multi-service requirements and battlespace characterization everywhere that U.S. forces operate.
Descreption
The Defense Meteorological Satellite Program (DMSP) designs, builds, launches, and maintains satellites monitoring the meteorological, oceanographic,terrestrial and solar environments. Using the DMSP data, military weather forecasters can detect developing patterns of weather and track existing weather systems over remote areas, including the presence of severe thunderstorms, dust storms, hurricanes, and typhoons. This data is vital to the effective employment of forces and weapon systems worldwide. The program includes five satellites flying in two sun-synchronous orbits.
The primary weather sensor on DMSP is the Operational Linescan System, which provides continuous visual and infrared imagery of cloud cover over an area 1,600 nautical miles wide. Additional satellite sensors measure atmospheric vertical profiles of moisture and temperature, sea surface winds, and the presence of soil moisture. The DMSP satellites also measure space environment charged particles and electromagnetic fields to assess the impact of the ionosphere on ballistic-missile early warning radar systems, electrical grids, satellite operations, and long-range communications.
Defense Satellite Communications System (DSCS) III
Provide super-high freqency satellite communications to troops in the field as well as commanders at multiple locations worldwide.
The Defense Satellite Communications Systems (DSCS) is the workhorse of military satellite communications. The system provides uninterrupted secure voice and high rate data communications to DoD users for monitoring events and deploying and sustaining forces anywhere in the world. It is used for high-priority command and control communication such as the exchange of wartime information between defense officials and battlefield commanders. The military also uses DSCS to transmit space operations and early warning data to various systems and users.
Descreption
The system consists of nine Phase III DSCS satellites that orbit the earth at an altitude of more than 22,000 miles. Each satellite uses six super high frequency transponder channels capable of providing secure voice and high data rate communications. The system also features a single-channel transponder for disseminating emergency action and force direction messages to nuclear-capable forces. The single steerable dish antenna
provides an increased power spot beam which can be tailored to suit the needs of different size user terminals. DSCS satellites can resist jamming and consistently exceed their 10 year design life. DSCS users operate on the ground, at sea, or in the air. Members of the 50th Space Wing’s 3rd Space Operations Squadron at Schriever Air Force Base, CO, provide satellite command and control support for all DSCS satellites.
