Claim 0:
1. A method for tracking Non-Geo Synchronous Orbit Satellites on Orbiting Planes of Regular Motion Patterns, the method comprising:
providing a first satellites moving in a direction descending in latitude in first orbital planes and a second satellites moving in a direction ascending in latitude in second orbital planes;
steering an antenna to an antenna tilt φ from normal with a single axis mechanism lined up with a first axis;
scanning, electronically, with a linear array at a scan angle ψ along a second axis;
locking to a signal from a handed-from satellite from a first satellites; and
selecting a handed-to satellite from the second satellites,
wherein the handed-from satellite and the handed-to satellite are Line-of-sight (LOS) from the antenna at an instant of a hand-off,
the first axis is angled from the second axis,
the steering along the first axis and the scanning along the second axis jointly track the handed-from satellite,
the first orbits are parallel,
the second orbits are parallel, and
the first orbits seem aligned with the antenna tilt φ.
