Abstract
X-band tracking of the Viking spacecraft in orbit around Mars will be complicated due to the combination of high periapsis doppler rates and low downlink carrier margin. This report presents methods to implement X-band tracking of the Viking spacecraft by ramping either the ground transmitter frequency or the ground receiver frequency. The operational impact of the two methods is assessed.
