Abstract:

The problem of pointing an instrument on the earths surface at an object in orbit about the earth was investigated. Necessary expressions were derived for calculating continuously azimuth, elevation, range, and range rate from inputs of instrument site and orbit parameters. An electromechanical orbit computer capable of performing the required mathematical operations is described. Test results are listed for a similar computer used against a typical orbiting body.
