NPOESS

The National Polar - orbiting Operational Environmental Satellite System ( NPOESS, about German National, polarumkreisend powered, environmental satellite system ) was a planned US-based satellite system to monitor the weather, the atmosphere, the oceans and the mainland. The NPOESS satellites should be based on proven technology and use already -proven sensors NASA. The planned start date of the first NPOESS satellite "C1" or " Charlie 1" was planned for 2013. Problems in the development of the sensors have been identified as the main cause of delays and cost overruns.

Operation

NPOESS should be by the Office of Satellite and Product Operation ( OSTS ) of the National Environmental Satellite, Data, and Information Service ( NESDIS ) of the National Oceanic and Atmospheric Administration ( NOAA) of the NOAA Satellite Operations Facility ( NSOF ) operated in Suitland from. Northrop Grumman Aerospace Systems ( NGAS ) was the primary system integrator for the project. Raytheon, Ball Aerospace & Technologies and Boeing developed the sensors.

NPOESS should replace the one hand, the DMSP satellites of the U.S. Defense Department as well as the POES satellites of NOAA. The NPOESS Preparatory Project ( NPP) was carried out as a prototype mission and started five years after the actual scheduled start 28 October 2011 into space.

The White House announced on February 1, 2010, which dissolved the NPOESS Partnerships and two satellite series to be launched into polar orbits for each military and civilian purposes:

  • The civilian part of NOAA and NASA called Joint Polar Satellite System ( JPSS ). JPSS -1 is designed and built by Ball Aerospace & Technologies with a fixed price of 248 million U.S. dollars to 1 February 2015. The ground segment is supplied by Raytheon. Meanwhile the Start bi has moved into the year 2017.
  • The military part is called the Defense Weather Satellite System ( DWSS ).
