The NOAA K, L and M POES satellites begin the fifth generation of improved environmental monitoring in support of NOAA missions. The instrument payload has significant improvements and additions/deletions. The instrument changes have effected the spacecraft subsystems and data formats.
The Titan 23G, Titan II(23)G, Titan 2(23)G or Titan II SLV was an American expendable launch system derived from the LGM-25C Titan II intercontinental ballistic missile. Retired Titan II missiles were converted by Martin Marietta, into which the Glenn L. Martin Company, which built the original Titan II, had merged. It was used to carry payloads for the United States Air Force, NASA and NOAA. Thirteen were launched from Space Launch Complex 4W at the Vandenberg Air Force Base between 1988 and 2003.
