Engineering/Service Test of AN/GRN-14( ) Position Fixing and Navigation System (PFNS).

摘要

The US Army Test and Evaluation Command (USATECOM) test directive for the engineering/service test of the AN/GRN-14( ) PFNS, a prototype development model, designated the US Army Aviation Test Board (USAAVNTBD) as a Participating Test Authority (PTA) with the US Army Electronic Proving Ground (USAEPG), Fort Huachuca, Arizona, designated as Coordinating Test Authority (CTA). The USAAVNTBD was directed to conduct those tests necessary to determine the suitability of PFNS for use by Army aviation. The USAAVNTBD invited the US Army Aviation Human Research Unit (USAAHUMRU) to participate in the service test. The concept of a low-frequency, hyperbolic navigation system, for the use of Army aviation, was evaluated by US Army Europe, during their test of the Decca Navigation System in 1959-1960. Hyperbolic grid navigation systems, Decca being but one type, are presently being used throughout the world and have been for more than twenty years.
