局域增强系统台站最小保护间隔的计算
Calculation of Minimum Protected Distance between Navigation Facilities for Local Area Augmentation System
摘要
Abstract
Focusing on the frequency assignment problem of Local Area Augmentation System( LAAS) ,this paper propose a method based on the concept of Frequency Protected Service Volume ( FPSV ) . Using the radio propagation model and space geometrical relationship, it describes the algorithm of calculating the minimum protected distance between the navigation facilities,which can guarantee the required signal-to-interference ratio of airborne receivers in FPSV. The numerical calculation result matches well with the reg-ulation given by Federal Aviation Administration(FAA),and the method is proved to be simple and effi-cient for frequency assignment on LAAS facilities. So the proposed method can improve spectral efficiency and solve the spectrum scarcity problem.关键词
