Laser Beam for External Position Control and Traffic Management of On-Orbit Satellites

Case ID:
UA19-036
Invention:

This invention is a satellite control system. The system consists of a customized “smart skin” containing solar panels, power and control circuitry, and an embedded secondary propulsion system. A laser is used from a ground station or another spacecraft and is beamed towards the satellite. The satellite has onboard photovoltaics that act as a wake-up laser receiver. This approach enables a laser ground station or a spacecraft to broadcast commands to the spacecraft in times of emergency that would trigger operation of the secondary propulsion system to perform impulse maneuvers, altitude control maneuvers, and corrections.

 

Background:
This technology offers several benefits over existing techniques, such as low initial investment, low power usage, high bandwidth, and high security. The “over-congestion” of key satellite orbits greatly decreases their utility, as collisions become far more likely. Adding an actuated reflector to the spacecraft will enable laser ranging and two-way communication between ground station and the spacecraft, in a secure manner not currently available to RF communication systems. There is a need to develop secondary and backup systems to effectively move these satellites and perform traffic management of derelict satellites so that collision risks are minimized or eliminated.

 

Applications:

  • On-orbit satellites
  • Optical communication technology
  • Small electronic devices
  • Government & military
  • Commercial & private entities


Advantages:

  • Low cost
  • Long-distance
  • Increased data
  • High bandwidth
  • Secure transmission

Status: issued U.S. patent #11,368,212
