Laser communication link ranging and timing
Last updated:
Abstract:
Provided herein are various improvements to laser communication ranging. In one example, a method includes converting a ranging signal in a radio frequency (RF) format into an optical format and combining the ranging signal in the optical format with data communications into an optical transmission for receipt by a communication node. The method also includes receiving from the communication node an additional optical transmission comprising additional data communications combined with a retransmitted version of the ranging signal, and determining an indication of a range to the communication node based at least on properties of the retransmitted version of the ranging signal.
