Abstract
A system and method for tracking non-geo synchronous orbit satellites on orbiting planes of regular motion patterns. The method includes 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; and locking to a signal from a handed-from satellite from the first satellites, where 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 seem parallel, the second orbits seem parallel, and the first orbits seem aligned with the antenna tilt φ. A handoff between the first satellites may use one of the second satellites as a steppingstone.
