Test Plan for Helicopter GPS (Global Positioning System) Applications
FEDERAL AVIATION ADMINISTRATION TECHNICAL CENTER ATLANTIC CITY NJ
Pagination or Media Count:
This test plan describes a project designed to collect data via flight testing from the Global Positioning System GPS when receivers are mounted on helicopters. GPS issues to be investigated include antenna location, satellite shielding , and multipath influences which might occur with rotorcraft applications in urban downtown areas. Minimum masking angle issues will also be addressed. GPS integrated with other navigation and guidance systems such as microwave landing system MLS and Loran C will also be investigated. Both precision P and coarseacquisition CA code receivers will be evaluated. In addition, studies will be carried out to determine how to install a GPS antenna on composite body aircraft. Further studies may be related to automatic dependent surveillance functions. Future work will include evaluation of a GPS P code receiver as a reference for flight inspection. Keywords Satellite Navigation.
