POSITION ERROR IN STATION-KEEPING SATELLITE

Abstract

An automatic station-keeping satellite must be able to measure its deviation from the nominal position. For the system considered here (an equatorial synchronous orbit) this involves a latitude difference measurement between the earth and sun at certain times. This report shows that a combination of an error in satellite orientation and the sun being in a plane other than the equatorial plane may result in errors in position determination. The nature of the errors involved is described and their magnitudes estimated.
