Airborne Global Positioning System Antenna System

摘要

This Military Standard Order (MSO) prescribes the minimum performance standard that airborne Global Positioning System (GPS) antenna system must meet to be identified with the applicable MSO marking. The similarity of this MSO with Technical Standard Order (TSO) -C144, 'Airborne Global Positioning System Antenna', is intentional. The standards of this MSO apply to antenna systems that will be used to receive and provide Link 1 (L1) and Link 2 (L2) signals to a GPS Precise Positioning Service (PPS) navigation sensor or system, which provides information used to guide an aircraft in Required Navigation Performance (RNP) airspace. These standards do not address the use of the signals received through this antenna system for other applications.
