Abstract
A system includes a transmitter and a processor. The processor is configured to receive true time at a terminal; acquire a first communication link with a satellite using a first protocol; determine a second communication link with the satellite using a second protocol; and provide the true time to the satellite in a constellation using the transmitter.
Claims18
A system, comprising:
- a transmitter;
- and
- a processor configured to:
- receive true time at a terminal;
- acquire a first communication link with a satellite using a first protocol;
- determine a second communication link with the satellite using a second protocol;
- and
- provide the true time to the satellite in a constellation using the transmitter, wherein the satellite determines a local satellite true time based at least in part on the received true time, and wherein the satellite sends the local satellite true time to another satellite in the constellation using a satellite transmitter;
- wherein providing the true time comprises transmitting a first short pulse or first high bandwidth signal;
- wherein providing the true time comprises measuring a time of arrival of a second short pulse or second high bandwidth signal;
- wherein providing the true time comprises receiving the second short pulse or the second high bandwidth signal after a precise time delay from the time of arrival of the first short pulse or the first high bandwidth signal at the satellite;
- and
- wherein providing the satellite time comprises transmitting a propagation time.
