A Low Cost Aircraft Precision Approach and Landing System to Support Antarctic Operations

点击翻译按钮获取中文摘要

This proposed aircraft landing system uses the Global Positioning System (GPS) in conjunction with special purpose ground equipment to provide a highly accurate, fully autonomous, portable precision approach and landing system. The aircraft receiver can also be used to support en-route navigation and non-precision approaches when out of range of the ground station. Under Phase I, the GPS precision approach and landing system will be designed to operate in the extreme Antarctic environment. The proposed precision approach and landing system will significantly improve safety at NSF facilities in Antarctica. GPS provides the capability of an "all-weather" landing system that can function equally well at fixed installations, filed sites, and can even operate on moving landing sites such as ice drifts without any degradation in performance.
