RADAR 'SAIL' SATELLITE CONCEPT AND DESIGN

摘要

The RADAR SAIL concept is based on the use of a rectangular antenna lying in the dawn dusk orbital plane with the length (along speed vector) smaller than the height. Such geometry makes it possible to place the solar cells on the back of the antenna, to use gravity gradient stabilisation, and (optionally) to implement multipath-free GPS interferometric measurement of the antenna deformation thus allowing structural relaxation.
