Satellite Motion Determination by Measuring Selected Frequency Triplets with a Fourier telescopy Facility

摘要

GLINT is a program to image geosynchronous satellites using Fourier telescopy. The standard method of creating an image takes some time requiring the satellite to be stationary for an hour or more. Important information about the satellite's motion and orientation can be obtained by measuring a small subset of the u-v sample space. These estimates can be useful in themselves-for instance as an aid to regaining control of the satellite. They can also be used as inputs to alternate imaging schemes that map out the u-v space synchronously with the rotating satellite.
