STUDY OF INTEGRITY, RELIABILITY, AND ACCURACY OF AUTOMATIC HEIGHT REPORTING SYSTEM VIA ATC RADAR BEACON SYSTEM.
Abstract
This study is divided into two phases. Phase I is concerned with: (1) code degradation resulting from synchronous and random interference, and (2) code-detection criteria. Analytical models include random and operationally controlled distributions of aircraft with emphasis on high-density areas. It is concluded that height data derived from this system will afford good integrity. Belief in the high code integrity of the automatic-altitude reporting system leads one to inquire about the accuracy of the system or whether the task can be performed more efficiently by another type of radar equipment. This is the essential subject matter of Phase II of the study. The accuracy of various altimetry systems is statistically assessed in terms of maintaining vertical separation. ICAO analyses of altimeters are used as a basis of evaluation with modifications included for the parameters of the automatic reporting system. It is concluded that the statistical accuracy of altitude data derived from the automatic reporting system, with regard to the effect on vertical separation, is not significantly different from that of comparable existing altimetry. In fact, an extra margin of safety should be attained by providing the controller with a means to monitor the flight technical error. Also, data rate and capacity of the ATCRBS is equal to or greater than that of other systems that have been considered. (Author)
