LOCATING A SATELLITE IN LOW-EARTH ORBIT - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240048225 titled 'LOCATING A SATELLITE IN LOW-EARTH ORBIT

Simplified Explanation

The abstract describes a computer-implemented method for operating a feeder link terminal to locate a satellite in low-earth orbit. The method involves accessing predicted location information for the satellite and determining an initial position to start scanning for the satellite. A substantially ellipsoidal region is defined to scan for the satellite, with a long axis corresponding to the predicted track of the satellite relative to the feeder link terminal, and a shorter axis corresponding to potential cross-track error. The feeder link terminal is then instructed to scan the ellipsoidal region for the satellite starting from the initial position.

  • The method involves accessing predicted location information for a satellite in low-earth orbit.
  • An initial position is determined to start scanning for the satellite.
  • A substantially ellipsoidal region is defined to scan for the satellite.
  • The ellipsoidal region has a long axis corresponding to the predicted track of the satellite relative to the feeder link terminal.
  • The ellipsoidal region has a shorter axis corresponding to potential cross-track error.
  • The feeder link terminal is instructed to scan the ellipsoidal region for the satellite starting from the initial position.

Potential Applications:

  • Satellite tracking and positioning systems.
  • Feeder link terminals for satellite communication networks.
  • Low-earth orbit satellite communication systems.

Problems Solved:

  • Efficiently locating and tracking satellites in low-earth orbit.
  • Minimizing cross-track error in satellite tracking.
  • Optimizing the scanning process for satellite detection.

Benefits:

  • Improved accuracy in locating and tracking satellites.
  • Enhanced efficiency in satellite communication systems.
  • Reduced cross-track error for better satellite positioning.
  • Streamlined scanning process for satellite detection.


Original Abstract Submitted

according to one implementation of the disclosure, a computer-implemented method of operating a feeder link terminal to locate a satellite in low-earth orbit includes accessing predicted location information for a satellite in low-earth orbit and determining an initial position at which to start a scan for the satellite. in addition, the method includes defining a substantially ellipsoidal region to scan for the satellite that includes the initial position, that has a long axis that corresponds to a predicted track of the satellite relative to the feeder link terminal, and that has a shorter axis that corresponds to potential cross-track error of the predicted track of the satellite. the method further includes causing the feeder link terminal to scan the ellipsoidal region for the satellite starting from the initial position.
