Abstract
Given the growing interest in satellite constellations, there is a surprising lack of
rigorously tested operations and control methods for constellations larger than 30
to 50 spacecraft. The purpose of this paper is to discuss the development of a
robust, modular and scalable system able to provide software-in-the-loop (SWIL)
and hardware-in-the-loop (HWIL) simulation capabilities for the advancement of
formation and constellation Flight Software Technology Readiness Levels (FSW
TRL). The system being developed is called COSMoS (COnstellation Simulation
on a Massive Scale). The goal of this system is to a) enable massive-scale
(100+ satellite) realistic testing and characterization of formation control and operations
techniques, b) examine the scaling of centralized and decentralized formation
guidance, navigation, and control algorithms, and c) improve Technology
Readiness Levels in realistic conditions. Examples of developing capabilities include
the implementation of control schemes using a Minimum Lyapunov Error
approach as well as semi- and fully-autonomous decision making systems.
