Adaptive Dynamic Inversion for Satellite Formation Flying
2021The benefit of satellite formation flying can truly be realized with greater mission flexibility such as higher inter-satellite separation, formation in elliptic orbits, etc. However, under the above-enhanced conditions, linear system dynamics based control design approaches fail to achieve the desired objectives.

Autonomous Relative Navigation for Formation Flying Satellites
2006 1st International Symposium on Systems and Control in Aerospace and Astronautics, 2006Autonomous navigation technology of formation flying satellites is one of the key technologies for formation flying. The objective of this paper is to derive a set of Hill-like equations suited for the tandem formation and investigate the relative state (including relative position, relative velocity and relative attitude) determination of satellites ...

Cooperative fault accommodation in formation flying satellites
2008 IEEE International Conference on Control Applications, 2008In this paper a new fault accommodation algorithm based on a two-level architecture is proposed for satellite formation missions. In this two-level framework, the notion of formation-level fault recovery (FLFR) is proposed, and the task of performance monitoring (PM) is defined in the high level (HL). By using the information provided by the PM module,

Autonomous control system for satellite formation flying
IEE Seminar on Autonomous Agents in Control, 2005Recently there has been an increase of interest in the concept of satellite formation flying due to the efficiency gains that can be obtained from using a large number of small crafts instead of one large one. In formation flying it is required that the satellites should fly in specified positions relative to the others and with specified attitudes ...

Relative orientation estimation in formation flying satellites
2017 International Symposium on Signals, Circuits and Systems (ISSCS), 2017Satellite precision formation flying (PFF) is a concept in which multiple spacecraft communicate via an inter-satellite link (ISL) and cooperate to achieve the goal of a single, more complex satellite. This enables the creation of virtual scientific structures such as interferometers or imagers that would not be deployable in space because of their ...

Finite-Time LQR and SDRE for Satellite Formation Flying
2021Even though the results of the infinite-time LQR, SDRE, DI approaches are seemingly easier to understand and implement and can lead to acceptable results with appropriate tuning, it is very important to understand that such approaches are not strongly recommended for satellite formation flying problems in general.

Satellite Formation Flying Control Using Image Processing
Mekhatronika, Avtomatizatsiya, Upravlenie, 2019A problem of a formation flying control is observed. As an example a concept of a multysatellite configuration ("space commercial") is described. Space advertisement is realized by groups of specialized free flying and cable-connected satellites, and their combinations.

Collision Avoidance Control for Formation Flying Satellites
AIAA Guidance, Navigation, and Control Conference, 2010This paper focuses on the design of a safe control method minimizing the collision hazard for satellites flying on near-circular orbits. The geometry of formation configuration is described based on the relative orbital elements, which is particularly efficient for relative orbit control design and proximity analyses.

EO Small Satellite Missions and Formation Flying
2009The aim of the ESA study on concepts for demonstration of advanced techniques and technologies on an EO small mission is to assess ideas for EO missions compatible with implementation on a small satellite such as PROBA, and which may benefit from Formation Flying.
