Abstract
Official abstract text for this publication.
An ephemeris refinement system includes satellites with imaging devices in earth orbit to make observations of space-based objects (“target objects”) and a ground-based controller that controls the scheduling of the satellites to make the observations of the target objects and refines orbital models of the target objects. The ground-based controller determines when the target objects of interest will be near enough to a satellite for that satellite to collect an image of the target object based on an initial orbital model for the target objects. The ground-based controller directs the schedules to be uploaded to the satellites, and the satellites make observations as scheduled and download the observations to the ground-based controller. The ground-based controller then refines the initial orbital models of the target objects based on the locations of the target objects that are derived from the observations.
First claim
Opening claim text (preview).
We claim: 1. A system for monitoring space-based objects, the system comprising: a plurality of satellites in earth orbit, each satellite having an imaging device that collects images, and a satellite controller that receives a schedule for collecting an image at a collection time and a collection orientation, orients the imaging device and collects the image in accordance with the schedule, and transmits information relating to the collected image; and a controller that in…
