Systems, methods and devices for use with unmanned aerial vehicles (UAV). A central controller is coupled to the autopilot system for a UAV. Navigation is implemented by using two GPS antennas and obtaining a difference between the locations from these two antenna to arrive at a high precision bearing or direction of travel. This single GPS derived bearing is used to trigger all the various subsystems on the UAV for imaging or mapping. Areas and locations to be mapped and imaged are determined by geolocation and mapping and imaging equipment are triggered based on the single GPS signal derived from the two GPS antennas. To reduce vibration effects on navigational and imaging or mapping equipment, these are positioned as close as possible to the vehicle's center of gravity and are deployed in a shielded box on vibration isolation mounts.

A foldable unit comprised of linkages in the form of tubular prisms is provided. The unit may be additionally comprised of polygonal panels. Linkages and panels correspond to a central polyhedral design that may be specified from a wide variety of geometric arrangements.
