Continuous multi-satellite tracking
First Claim
1. Electromagnetic multi-satellite reception device comprising:
- at least two sensors; and
means for pointing said sensors towards respective, separate satellites wherein the pointing means comprises;
an electromagnetic lens having a substantially continuous focal surface, at least for a substantial part of a celestial half-space, and a mount slidably mounting said at least two sensors on a rail for movement relative to each other, said rail independently, separately and individually positioning said sensors adjacent said focal surface at substantially any useful point thereof, and means for the control of the mount and the position of each of said sensors relative to another of said sensors as a function of position data for the satellites.

Abstract
The pointing of at least two sensors (61, 62) is ensured through a Luneberg lens (50). A first frame (20) pivoting on a support (10), supports in pivoting manner a second frame (30), which can in turn support the lens (50). The second frame (30, 40) supports at least one rail (41) for guiding the sensors in the vicinity of the focal surface of the lens. Control means (90) act on the mount as a function of data concerning the position of satellites to be sighted. They are arranged so as to temporarily stop the sighting of one of the satellites, bring the mount into an opposite position on the focal surface, whilst continually sighting the other satellite, and resume the sighting of both satellites, the two sensors then being in an inverted position on the rail.

11. Electromagnetic multi-satellite reception device comprising:
-
at least two sensors;
pointer for pointing said sensors towards respective, separate satellites, wherein the pointer comprises;
an electromagnetic lens having a substantially continuous focal surface, at least for a substantial part of a celestial half-space, and a mount slidably mounting said sensors on a rail for movement relative to each other, said rail separately, independently and individually positioning said sensors adjacent said focal surface at substantially any useful point thereof, and a mount controller, responsive to satellite position data, for moving the mount and the position of each of said sensors relative to another of said sensors to enable the satellites to be tracked by said at least two sensors.

at least two sensors; and
means for pointing said sensors towards respective, separate satellites, wherein the pointing means comprises;
an electromagnetic lens having a substantially continuous focal surface, at least for a substantial part of a celestial half-space, and a mount slidably mounting said at least two sensors on a rail for movement relative to each other, said mount providing three degrees of freedom rotation for each of said sensors, with said rail separately, individually and independently positioning said sensors adjacent said focal surface at substantially any useful point thereof, and means for the control of the mount and the position of each of said sensors relative to another of said sensors as a function of position data for the satellites.
