Abstract

An analysis is given of possible interference induced by a position marker system, called RASP, into aircraft radio altimeters. The RASP system is used as a marker beacon in flight tests for trajectory measurements, and operates on 4.3 GHz. It is concluded that radio altimeters will not experience any harmful interference from a RASP transmitter.
