1. A method for correcting for time delay variations between a plurality of selectable signal paths from a signal source to at least one transmit antenna of a satellite, the method comprising:

  • measuring a time delay for each of the plurality of selectable signal paths; and

    correcting a signal for a time delay variation based on the time delay for a currently used signal path that is being used by the satellite to transmit the signal to a receiver, the currently used signal path being selected from the plurality of selectable signal paths from the signal source to the at least one transmit antenna by a switch mechanism and the corrected signal being usable for at least one of navigation, determining a geographic location and determining time.
