Flying spacecraft detection with the earth as the background based on superpixels clustering

2015 IEEE International Conference on Information and Automation, 2015
On orbit flying spacecraft detection in near range is of great significance to space based surveillance and the final stage of rendezvous & docking. In this paper, we propose an effective flying spacecraft detection algorithm with the earth as the cluttered dynamic background based on superpixels clustering.

CLUSTER spacecraft observation of a thin current sheet at the Earth’s magnetopause

Advances in Space Research, 2006
Abstract On March 30, 2002 within 17 min the four CLUSTER spacecraft crossed the Earth’s high-latitude magnetopause three times. We found that all three magnetopause current sheets are nearly co-planar on the scales of the CLUSTER spacecraft separation.

Spacecraft Recognition in Co-Located Satellites Cluster Through Optical Measures

IEEE Transactions on Aerospace and Electronic Systems, 2017
The optical orbit determination is one of the most important ways for noncooperative object tracking. One of the main problems with noncooperative object tracking is its recognition through different nights. In this study, the conditions that ensure the recognition of a geostationary satellite inside a cluster were assessed through a hard real case ...

HIGH PERFORMANCE PROCESSING CLUSTER FOR REMOTE SENSING SPACECRAFTS

Journal of Rocket-Space Technology, 2021
Recently, there has been a tendency to complicate real time control algorithms, to process a large amount of information from the satellite payload (optical, radar, communication systems) directly on board and to create highly informative communication lines with both ground stations and other satellites.

Quasi-linear optimization for multiple-spacecraft clustering

2005
Several missions have utilised halo orbits around the L1 and L2 Lagrange points of the Earth-Sun system. Due to the instability of these orbits, station-keeping techniques are required to prevent escape after orbit insertion. This paper considers using solar sail propulsion to provide station-keeping at quasi-periodic orbits around L1 and L2.

Cluster Spacecraft Observations of Magnetopause Reconnection at Multiple Scales

2013
Magnetic reconnection is an inherently multi-scale process where the dynamics at small-scales strongly affect the large-scale evolution of the process. The microphysics of reconnection (i.e. the physics at proton scales and below) is particularly important.
