A geostationary dish points once and never moves. A Starlink terminal tracks satellites that cross the whole sky in a few minutes and hand off constantly. US11943042B2, granted to SpaceX on March 26, 2024, claims the machinery behind that, covering "facilitating satellite visibility for earth-based antenna systems."
The CPC is satellite-comms operations: H04B 7/18513, 7/18517, and 7/18558 — all within transmission systems using satellites, covering link establishment and management. No antenna-hardware codes; this is an operations-and-coordination claim, not a metal claim.
The mechanism is visibility orchestration and handoff. The system works out which satellites are above the horizon and usable for a given ground terminal at a given moment, and manages the transition as one satellite sets and another rises. Get it wrong and the user sees dropouts; get it right and a constellation of fast-moving satellites feels like a continuous connection. At Starlink's scale — millions of terminals, thousands of satellites — this coordination is as much a part of the product as the radios.
This is the unglamorous operational IP that makes a megaconstellation usable. The antenna is the architecture, but the schedule of which satellite to talk to and when is the nervous system. SpaceX's portfolio is thick with these operations-layer claims precisely because the hardware advantage erodes while the coordination know-how compounds.
Claim-scope honesty: this protects SpaceX's specific apparatuses and methods for satellite-visibility handling, not the general concept of LEO handoff, which any constellation operator must solve. Its value is defensive coverage over how Starlink actually keeps users connected. For analysts, it is confirmation that in a constellation, the software that decides where to point is core, patentable IP.
