Abstract:
A method for correcting for time delay variations between a plurality of signal paths from a signal source to at least one transmit antenna of a satellite may include measuring a time delay for each of the plurality of signal paths. The method may also include correcting a signal for the time delay variation based on the time delay for the signal path that is currently being used by the satellite, the corrected signal being usable for at least one of navigation, determining a geographic location and determining time.
