Abstract
A system for communication between two communication platforms, including a near-earth returning platform and a remote platform. A bidirectional asymmetrical communication link is set up between the two platforms.
Claims18
A system for communication between two communication platforms, comprising:
- a near-earth returning platform including a laser and a heterodyne modulator coupled to the laser, wherein the heterodyne modulator is configured to modulate laser light received from the laser according to a heterodyne modulation;
- and
- a remote platform including a laser and an amplitude modulator coupled to the laser, wherein the amplitude modulator is configured to modulate laser light received from the laser according to an amplitude modulation;
- and
- a bidirectional asymmetrical communication link that couples the near-earth returning platform and the remote platform, wherein the bidirectional asymmetrical communication link includes an uplink communication link from the near-earth returning platform to the remote platform carrying heterodyne modulated signals and a downlink communication link from the remote platform to the near-earth returning platform carrying amplitude modulated signals.
