A Study of Aerial Semi-Precise Survey Systems for Position Auditing of Coast Guard Aids to Navigation.

摘要

A study was undertaken to evaluate aerial imaging systems capable of establishing the position of aids to navigation to within 30 meters within 48 hours following adverse weather conditions such as ice or storm. A scenario area (400 km by 3 km) was created to simulate a region affected by such environmental conditions. The study considered aerial photograph, side-looking airborne radar, and visual observations from aircraft. It was concluded that there are no systems currently available to the Coast Guard to achieve an aerial semi-precise survey of aids to navigation. (Author)
