Mixed Initiative Scheduling for the Air Force Satellite Control Network
Scheduling access to Air Force satellites is an over-constrained problem. Over 500 requests for access are received for each day's operation; after manual scheduling, over 100 con icts typically remain in the schedule. We are developing a prototype scheduling system that will assist human schedulers in this problem. Automated scheduling promises to reduce the number of con icts, but will never ...
متن کاملScheduling Space-Ground Communications for the Air Force Satellite Control Network
We present the first coupled formal and empirical analysis of the Satellite Range Scheduling application. We structure our study as a progression; we start by studying a simplified version of the problem in which only one resource is present. We show that the simplified version of the problem is equivalent to a well-known machine scheduling problem and use this result to prove that Satellite Ra...
متن کاملRandom Walks and Neighborhood Bias in Oversubscribed Scheduling
This paper presents new results showing that a very simple stochastic hill climbing algorithm is as good or better than more complex metaheuristic methods for solving an oversubscribed scheduling problem: scheduling communication contacts on the Air Force Satellite Control Network (AFSCN). The empirical results also suggest that the best neighborhood construction choices produce a search that i...
متن کاملAFSCN scheduling: How the problem and solution have evolved
The Air Force Satellite Control Network (AFSCN) coordinates communications to more than 100 satellites via nine ground stations positioned around the globe. Customers request an antenna at a ground station for a specific time window along with possible alternative slots. Typically, 500 requests per day result in more than 100 conflicts, which are requests that cannot be satisfied because other ...
متن کاملExploiting AFSCN Ranging Data for Catalog Maintenance
The Air Force Satellite Control Network (AFSCN) is composed of eight worldwide fixed remote tracking stations (Space Ground Link Stations, SGLS) hosting 15 antennas, plus two mission control nodes, one at Onizuka AFB, CA and the other at Schriever AFB, CO. One of the AFSCN message formats provides AFSCN metric data (range, range-rate, azimuth, and elevation). Currently the AFSCN metric data are...
