Abstract: A remote elevated platform (REP) for positioning a payload from an aircraft nd maintaining its position unattended, comprises a lifting body, a payload designed to be suspended from the lifting body, a tether line and a mooring system. The platform is dropped from the aircraft and the lifting body is deployed by opening it up by means of a static line or a barometric device. The mooring system is then released and it starts falling freely but attached to the tether line. The mooring line then strikes the surface and fixes itself in the ground. In a body of water, a float and sea anchor is deployed instead.

Abstract: A self-deploying and a self-aligning linear acoustic detector which can be ir dropped. The detector includes a parachute for deployment and has a mast, set of sails and booms for deploying and aligning an array of the detector. A neutrally buoyant array cable includes a plurality of neutrally buoyant hydrophones attached along its length which can be deployed horizontally at a predetermined depth in water. The array is also provided with a drogue at one end thereof to facilitate deployment of the array and to prevent it from moving after its deployment. The array is also provided with an auxiliary buoy for establishing the operating depth of the drogue and of the array. Ballast weights are provided to keep the mast vertical and to carry the array cable to a predetermined depth and keep it in a horizontal position after its deployment.
