Abstract
A terminal and antenna system (1, 10) for transmitting and receiving radio signals to and from satellites (2, 3) chosen from a constellation of non-geostationary satellites, including means for determining the position of the satellites visible from the terminal and antenna system, means for focusing quasi-plane waves received from or transmitted to a chosen visible satellite towards a focal surface S, primary sources (23, 24) for transmitting and receiving signals in the form of quasi-spherical wave beams, mobile independently over the sphere S in a manner that is slaved to the particular position of the non-geostationary satellites.
