Sun-synchronous Satellites - United States

This a list of satellites in sun-synchronous orbit operated by the USA. Names are not necessarily those by which they are known in the NORAD catalogue used by SpaceTrack.

It is a snapshot and is updated daily. The measure that results in an entry in this table is that the drift rate of LTDN (Local Time at the Descending Node) is no more than twenty four minutes each year. Some satellites may have higher drift rates but they may still be acceptable to their owners/operators. They do not appear here. On the converse, although a satellite is in a sun-synchronous orbit, it is not necessarily active.
