Hybrid Configurations for Satellite Constellations

, 1998
Orbital configuration design for satellite constellations is currently based on strongly regular models, as they make easier the coverage analysis. This paper deals with the widening of these symmetry constraints, leading to the so-called hybrid configurations.

A Novel Constellation of Satellites

2006 2nd International Conference on Information & Communication Technologies, 2006
A novel constellation of low earth equatorial orbit (LEQ) satellites is proposed to provide continuous coverage for countries with maximum latitude limit of plusmn25deg. Analysis and computer simulation results show that for such coverage with a minimum elevation angle of 10deg, a maximum number of 16 LEQ satellites is required.
