Multi-Step Automated Deconfliction for Satellite Communications Scheduling

This paper presents a description of a method to allow software to automatically deconflict competing supports. It primarily consists of sets of business rules associated with sets of individual satellites that the rules apply to. Once defined, the business rules can be utilized in several different ways to achieve a 95% deconflicted solution as described in the results section. Planned future ...

Scheduling Downloads for Multi-Satellite, Multi-Ground Station Missions

In this paper we address the deterministic, multi-satellite, multi-ground station communication scheduling problem. As the number of small satellites in space increases, so does the demand for downloading their large quantities of acquired data. Given the capacity-constrained ground station network, efficient scheduling plays a major role in the overall performance of missions. The small-satell...

Terrestrial to Satellite Communications Using Multi-antenna Relays Nodes

Satellite communications and relaying techniques have been receiving the attention of the research community over the last years. This paper proposes a terrestrial to satellite communication system aided by terrestrial relay nodes to facilitate a robust, reliable, and efficient communication link and improve the spectral efficiency. In particular, this paper concentrates on evaluating the spect...

Multi-Objective Reinforcement Learning for Cognitive Radio–Based Satellite Communications

Previous research on cognitive radios has addressed the performance of various machinelearning and optimization techniques for decision making of terrestrial link properties. In this paper, we present our recent investigations with respect to reinforcement learning that potentially can be employed by future cognitive radios installed onboard satellite communications systems specifically tasked ...
