Analysis of Cluster spacecraft potential during active control
Advances in Space Research, 2005Abstract The floating potential of a spacecraft is determined by an equilibrium between photo-electron emission from the sunlit spacecraft surfaces and the plasma electron current, while other currents play a secondary role. On the Cluster spacecraft, the presence of the experiment ASPOC to control the potential by an ion beam with currents up to ...

Spacecraft Recognition in Co-Located Satellites Cluster Through Optical Measures
IEEE Transactions on Aerospace and Electronic Systems, 2017The 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 ...

Decentralized autonomous planning of cluster reconfiguration for fractionated spacecraft
Acta Astronautica, 2016Abstract Autonomous cluster operation such as cluster reconfiguration is one of the enabling technologies for fractionated spacecraft. By virtue of the multi-agent system theory, this paper presents an organizational architecture for fractionated spacecraft, which not only enables autonomous cluster operations but also facilitates its non-traditional

Explicit Dipole Trajectory Solution for Electromagnetically Controlled Spacecraft Clusters
Journal of Guidance, Control, and Dynamics, 2010Satellite formation flight is a much-anticipated technology for future space-science missions, such as high-resolution space-based telescopes. A potentially enabling technology under development allows clusters of spacecraft to maneuver without the use of propellant, instead using electromagnetic control of the relative degrees of freedom within the ...

Nursing 4 Cluster Spacecraft with Aging Batteries Through Eclipses
SpaceOps 2008 Conference, 2008The Cluster mission was launched in 2000 to investigate for 3 years the interaction between the solar wind and the Earth magnetosphere. The mission has been extended until end 2009. The batteries of the four spacecraft are well beyond their design life and have started to fail.

Hybrid Laser/Microwave Wireless Communication System for Fractionated Cluster Spacecraft
Applied Mechanics and Materials, 2014Compared with conventional a single, “monolithic” satellite, fractionated cluster spacecraft system has the advantages of enhancing the adaptability and survivability of space systems while also shortening development expense. A novel wireless communication system that combines both microwave and laser technology has been investigated and demonstrated.

Cluster Spacecraft Observations of Magnetopause Reconnection at Multiple Scales
2013Magnetic 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.
