Space-Based Space Surveillance with the Space-Based Visible
Journal of Guidance, Control, and Dynamics, 2000Space surveillance is the activity of keeping a current catalog of information on manufactured, Earth-bound resident space objects. Some necessary functions to perform this task are search and detection, acquisition and tracking, tasking and scheduling, and data reduction and processing.

Space-Based Visible Space Surveillance Performance
Journal of Guidance, Control, and Dynamics, 2000The Space-Based Visible sensor package on the Midcourse Space Experiment satellite has been used to conduct space surveillance experiments for nearly one and a half years. The long-term detection sensitivity and metric performance of Space-Based Visible using onboard signal processed data are described.

Privacy in video surveilled spaces
Journal of Computer Security, 2008We present a system prototype for self-determination and privacy enhancement in video surveilled areas by integrating computer vision and cryptographic techniques into networked building automation systems. This paper describes a system prototype and research work that has been conducted by an interdisciplinary team of researchers.

Simulation of space-based visible surveillance images for space surveillance
SPIE Proceedings, 2011The simulation of space-based visible surveillance images can offer technical support to the index argumentation, scheme design and ground-tests of spatial optical system. Based on the analysis of the space-based visible surveillance principle, this paper establishes the simulation framework of space-based visible surveillance images, as well as its

Space Surveillance, Asteroids and Comets, and Space Debris. Volume 1: Space Surveillance
1997Abstract : This Study was produced by the Air Force Scientific Advisory Board. It was requested by the Commander Air Force Space Command and approved by the Secretary and Chief of Staff of the Air Force. It covers three topics, each of sufficient depth to be study of its own: Space Surveillance, Asteroid and Comet Impact Warning for Earth, and Space ...

Spaces of Appearance and Spaces of Surveillance
Polity, 2012Hannah Arendt and Michel Foucault developed different but complementary theories about visibility and power. In an Arendtian “space of appearance,” the common visibility of actors generates power, which is understood as the potential for collective action. In a Foucauldian “space of surveillance,” visibility facilitates control and normalization. Power
