Patent ID: 8528025

Claim:
An apparatus for compensating for drift in a satellite tuning device, comprising: a tuner configured to tune to a channel carried on a transponder signal; a compensator associated with the tuner, the compensator configured to: determine an offset value for the transponder signal; add the offset value to a center frequency; searching a frequency band around the center frequency within a deviation of a first size; the compensator further configured to execute the following actions in the event that the transponder signal is located within the frequency band at a perceived frequency: set the offset value to equal the difference between a standard frequency for the transponder signal and the perceived frequency; and store the offset value in an entry; and the compensator further configured to execute the following actions in the event that the transponder signal is not located within the frequency band at the perceived frequency: increment the size of the deviation such that the deviation is a of second size; search the frequency band around the center frequency within a deviation of the second size; locate the transponder signal within the frequency band at the perceived frequency; set the offset value to equal the difference between a standard frequency for the transponder signal and the perceived frequency; and store the offset value in an entry.
