Satellite over satellite (SOS) network: a novel architecture for satellite network
Proceedings IEEE INFOCOM 2000. Conference on Computer Communications. Nineteenth Annual Joint Conference of the IEEE Computer and Communications Societies (Cat. No.00CH37064), 2002Satellite systems have been proposed recently for broadband data and multimedia services. And many of them need a great number of satellites to provide broadband services with limited frequencies, and each satellite may have a number of direct intersatellite links (ISL) that are mutually visible satellites.

Satellite engineering for communications satellites
1999This chapter outlines the design drivers of a geostationary satellite before describing the individual subsystems of a three-axis-stabilised satellite. Orbit fundamentals and a brief overview of launch vehicles are also covered.

Filtering of satellite-to-satellite observations
Acta Astronautica, 1979Abstract This study addresses criticism of the low-low satellite-to-satellite methodology to obtain the small-scale gravitational structure of a primary gravitating body. Specifically, the aliasing of satellite-to-satellite range-rate observations from errors in the initial conditions of the orbits is studied numerically.

Science, 1999
NASA's Galileo mission to Jupiter and improved Earth-based observing capabilities have allowed major advances in our understanding of Jupiter's moons Io, Europa, Ganymede, and Callisto over the past few years. Particularly exciting findings include the evidence for internal liquid water oceans in Callisto and Europa, detection of a strong intrinsic ...

Satellites rock! [satellite radio]
IEE Review, 2003Is part of the world tuning into satellite radio? Noah Samara, the chairman and CEO of WorldSpace, founded the company in 1990. Using untapped bandwidth in the gigahertz spectrum and the broad geographical coverage of a satellite beam, he envisaged a revolution in radio broadcasting.

Planck is the third Medium Size mission of the ESA Horizon 2000 Science Program. It is devoted to Cosmology and Astrophysics and will be launched in March 2007 together with Herschel Space Observatory. Planck is designed to image the anisotropies of the Cosmic Microwave Background Radiation (CMBR) over the whole sky, with unprecedented sensitivity and ...
