Abstract: An improved system is provided suitable for use in landing an aircraft (for example, helicopter, RPV, VTOL) on shipboard comprising a support, base, platform or housing, reciprocal from remote a landing area on the deck of a ship to a position proximate the landing area, the housing carrying an upwardly directed light sensor comprising a lens system and a pair of band-pass filters, one filter before the lens system of the sensor and one after the lens system, the filters each passing the identical wavelength of light at its center but which each need not have the same band width as the other, a pulse detector in close proximity to the upwardly directed light sensor, and means for securing the aircraft to the support, housing, base or platform.

Abstract: A system for capturing a remotely piloted vehicle, the remotely piloted vehicle including a snagging line having a mechanism to be snagged at the end thereof. The system includes a snag mechanism for snagging the line of the remotely piloted vehicle, and a mechanism which funnels or guides the snag line on the remotely piloted vehicle to the snag mechanism of the system.

Abstract: An RPV, comprising means for engaging a snag line carried as part of a securing system which "snags" means (for example hook) on an RPV and assists the RPV to a safe landing, the snag line extending from a winch unit proximate the proposed landing area of the RPV to a position on the ship to which it is removeably secured and the end thereof carrying means to be secured to means on the RPV.

Abstract: An RPV for use on shipboard, the RPV having a lower support (for example a plurality of legs) comprising a plurality of broad pads at the lower end, a downwardly extending probe (or finger) extending from each pad, the lower end carrying wings within the probe that may be extended from the probe to extend laterally for securing below a grid through which each probe (or finger) may extend.
