The GEOSAT spacecraft was launched in March 1985 from Vandenberg Air Force Base, Calif. The 1400-pound spacecraft was placed in an 800-kilometer circular orbit with an inclination of 108 degrees. In March 1985, attitude capture and system checkout were complete and the mission was declared operational. Through the completion of the 18-month geodesy mission in September 1986, the spacecraft provided uninterrupted support for precision radar altimetry and tracking. The velocity control subsystem was then used to achieve a 17-day exact repeat orbit in November 1986. The orbit has since been maintained within 1 kilometer of Exact Repeat Mission ground tracks, and data collection continues.
