Abstract
Embodiments include one or more high altitude, long endurance (HALE) unmanned aircraft (110) capable of persistent station-keeping having one or more electromagnetic (IR/Visual/RF) sensor elements or suites (112, 337) for purposes of survey and/or signal gathering. Embodiments include one or more high altitude, long endurance (HALE) unmanned aircraft (110) capable of persistent station-keeping having a directable laser (331). Embodiments include a group of four or more high altitude, long endurance (HALE) unmanned aircraft (611-614) configured as GPS repeaters.

A method of satellite sensor interdiction, comprising:
- deploying a first high altitude, long endurance (HALE) unmanned aircraft comprising a satellite tracker and a directable electromagnetic (EM) radiation emitter in cooperation with the satellite tracker;
- acquiring, by the satellite tracker, a satellite having an onboard EM sensor;
- tracking, by the satellite tracker, the acquired satellite;
- emitting interdicting EM radiation, by the directable EM radiation emitter, to the tracked satellite;
- prior to the step of emitting by the first HALE unmanned aircraft, deploying a second HALE unmanned aircraft comprising a satellite tracker;
- signaling by the first HALE unmanned aircraft to the second HALE unmanned aircraft, the location of the tracked satellite;
- acquiring, by the satellite tracker of the second HALE unmanned aircraft, the satellite tracked by the first HALE unmanned aircraft;
- and
- tracking, by the satellite tracker of the second HALE unmanned aircraft, the satellite tracked by the first HALE unmanned aircraft.
A system for satellite sensor interdiction comprising:
- a first high altitude, long endurance HALE unmanned aircraft comprising:
- a satellite tracker and a directable electromagnetic (EM) radiation emitter in cooperation with the satellite tracker wherein the satellite tracker is configured to acquire and track a satellite having an onboard EM sensor;
- and wherein the directable EM radiation emitter is configured to emitting interdicting EM radiation to the EM sensor of the tracked satellite;
- a second HALE unmanned aircraft comprising a satellite tracker, wherein the second HALE unmanned aircraft is configured to receive, via signaling by the first HALE unmanned aircraft or via signaling via a ground station, the location of the tracked satellite;
- wherein the satellite tracker of the second HALE unmanned aircraft is configured to acquire the satellite tracked by the first HALE unmanned aircraft;
- and wherein the satellite tracker of the second HALE unmanned aircraft is further configured to track the satellite tracked by the first HALE unmanned aircraft.
