A Technology Survey Of Emergency Recovery And Flight Termination Systems For Uas, Richard Stansbury, Wesley Tanis, Timothy Wilson
A Technology Survey Of Emergency Recovery And Flight Termination Systems For Uas, Richard Stansbury, Wesley Tanis, Timothy Wilson
Richard Stansbury
For safe flight in the National Airspace System (NAS), either under the current interim rules or under anticipated longer-term regulatory guidelines facilitating unmanned aircraft system (UAS) access to the NAS, the UAS must incorporate technologies and flight procedures to ensure that neither people nor property in the air, on the ground, or on or in the water are endangered by the failure of an onboard component, by inappropriate unmanned aircraft (UA) response to pilot commands, or by inadvertent entry by the UA into prohibited airspace. The aircraft must be equipped with emergency recovery (ER) procedures and technologies that ensure that …

This paper presents preliminary work and a prototype computer vision optical method for latency measurement for an UAS (Uninhabited Aerial System) digital video capture, encode, transport, decode, and presentation subsystem. Challenges in this type of latency measurement include a no-touch policy for the camera and encoder as well as the decoder and player because the methods developed must not interfere with the system under test. The goal is to measure the true latency of displayed frames compared to observed scenes (and targets in those scenes) and provide an indication of latency to operators that can be verified and compared to …
