Abstract
A thermal distortion estimation system for delivering thermal time varying distortion of various spacecraft antenna is provided which includes a measurement signal outage indicator and a storage device containing time varying distortion data. A signal is generated indicating an outage for the system received by the spacecraft and then a generated time varying distortion of the system from a previous measurement history to predict the error resulting from the thermal distortion is employed to estimate the error.
