Abstract:

A ground-control system for a fleet of satellites provides a highly reliable means that automatically recognizes undesirable telemetry state changes and automatically transmits the required commands to the proper satellite to place the satellite operational parameters into the desired state. The ground-control system utilizes hardware, software and two redundant ground-control sites: a Control site and a Monitor site. There may also be a number of disabled sites to replace one of the redundant ground-control sites, at a moments notice, if necessary. Both redundant sites constantly and independently monitor and verify validity of satellite telemetry. Upon occurrence of an undesired state change (event) upon a particular satellite, ground-control computers at both sites independently recognize the event and automatically begin a response. The control site computer verifies no critical satellite on-board commanding is scheduled to take place, discontinues interruptible activities, directs the monitor site computer to stop any transmission to the event satellite, switches the RF hardware to access the proper satellite and transmits the required commands. If the control site computer cannot interrupt its own activities, it directs the monitor site computer to verify no critical satellite on-board commanding is scheduled to take place and then discontinues interruptible activities to transmit the required commands.

Abstract:

An N-Tiered enterprise and/or N-Tiered Web-based enterprise system and methods for managing, monitoring, coordinating the procedures of and optionally controlling a fleet of geosynchronous satellites through a distributed network such as the Internet. The system and associated object oriented software architecture seamlessly supports monitoring and analyzing real-time, near real-time, historical/playback, simulated and archived satellite telemetry as well as Tracking, Telemetry and Control (TT&C) ground system generated data products such as real-time alerts, archived alerts and ground system server statuses from a group of legacy distributed TT&C wide area network (WAN) ground station systems located around the world.
