American satellite dedicated to geodesy

Geotail was a satellite that observed the Earth's magnetosphere. It was developed by Japan's ISAS in association with the United States' NASA, and was launched by a Delta II rocket on 24 July 1992 from Cape Canaveral Air Force Station.

The concept of Timation was to broadcast an accurate time reference for use as a ranging signal to receivers on the ground.

SECOR (Sequential Collation of Ranges) was a series of small United States Armed Forces satellites launched in the 1960s for geodesy measurements that precisely determined the locations of points on the Earth's surface, particularly of isolated islands in the Pacific Ocean. This data allowed for improved global mapping and precise positioning of ground stations for other satellites.

1960s experimental communications satellites

TacSat-2 is the first in a series of U.S. military experimental technology and communication satellites.TacSat-2 (also known as JWS-D1 ((Joint Warfighting Space-Demonstrator 1) or RoadRunner) was an experimental satellite built by the USAF's Air Force Research Laboratory with an operational life expected to be not more than one year as part of the "Advanced Concept Technology Demonstration" program.
