| 发明名称 | Correcting for time delay variation in a satellite for positioning, navigation or timing applications | ||
| 摘要 | 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. | ||

| 主权项 | 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. | ||
