INVESTIGATION AND DEVELOPMENT OF MODIFICATIONS TO RESOLVE AIRBORNE/GROUND GLIDEPATH TRACKING PROBLEMS.

Abstract

Investigations were made to ascertain the cause or causes of tracking errors (discrepancies in course information derived from two separate glide path antennas) observed by FAA flight-check aircraft. A null reference/capture effect facility was installed at Mosby, Missouri and numerous tests were made. Most tests were made with a portable crankup tower to probe the path but flight checks were made, also. It was concluded that tracking errors are observed because: (1) There are vertically polarized components of signal in space that contain false course information. (2) The two aircraft receiving antennas do not reject these vertical signals sufficiently and differ in their degree of rejection of these vertical signals. (Author)
