Abstract:	Demonstrations of GPS-based approach and landing systems have caused many potential users of the Microwave Landing System (MLS) to question whether it is appropriate to install such a costly system. An investigation of the resistance to electromagnetic interference of Standard Positioning Service (SPS) C/A-code GPS receivers in aviation environments demonstrated their susceptibility to inband noise; for example, 1 W of radiated power jammed an airborne receiver at ranges in excess of 30 km. Although resistance to out-of-band interference is significantly greater, transmissions from communications systems in frequencies. adjacent to the GPS bands present considerable problems for GPS reception. Consequently, the use of C/A-code receivers for applications requiring high reliability and integrity, such as approach and landing, must be questioned.
