Oral presentation at the conference

This paper derives a control concept for far range Formation Flight (FF) applications assuming circular reference orbits. The paper focuses on a general impulsive control concept for FF which is then extended to the more realistic case of non-impulsive thrust maneuvers. The control concept uses a description of the FF in relative orbital elements (ROE) instead of the classical Cartesian...

163. ASTOS 8.1 - Mission Performance Analysis, System Concept Analysis and Other New Features

Mr Sven Weikert (Astos Solutions GmbH)

03: Satellite Constellations and Formations

Oral presentation at the conference

The ASTOS software was originally designed as a trajectory optimization tool for launchers. This was more than 25 years ago. Since then the software had been continuously developed towards a multi-purpose analysis, simulation and optimization software for nearly all kind of space scenarios. This paper shall present the latest extensions of ASTOS incorporated into release 8.1. The paper will...

141. Capitalizing on Relative Motion in Electrostatic Detumble of Axi-Symmetric GEO Objects

Trevor Bennett (University of Colorado Boulder)

03: Satellite Constellations and Formations

Oral presentation at the conference

Touchless methods of actuating and detumbling large Earth-orbiting objects is of increasing importance for active debris mitigation strategies. Previously developed are electrostatic detumble dynamics and simulations for deep-space and lead-follower formations. This study investigates the influence of the instantaneous position and relative formation on electrostatic detumble performance....

46. Analysis of Electric Propulsion Capabilities in Establishment and Keeping of Formation Flying Nanosatellites

Mr EVIATAR EDLERMAN (Technion)

15/03/2016, 17:20

03: Satellite Constellations and Formations

Oral presentation at the conference

Nanosatellite clusters constitute one of the current and future trends in space technology. [1] These clusters can be used in a variety of applications including search and rescue, communication, earth monitoring, etc. In order to maintain a satellite cluster over a long period of time it is required that the inter-satellite distances between the cluster agents will be controlled. [2] The...

174. Robust Control Design Methodology of the 6DoF Flight-Formation of PROBA-3

Mr Daniel Serrano (SENER)

15/03/2016, 17:40

03: Satellite Constellations and Formations

Oral presentation at the conference

PROBA-3 is one of ESA’s technology demonstrators, which consists of two spacecraft flying in close formation in a highly elliptic orbit. Its aim is to create a Sun coronagraph instrument with the optical payload and the external occulter disc mounted on different spacecraft. One of its main challenges is to develop the GNC that maintains a flight-formation during the apogee arc with very...
