A Preliminary Evaluation of the ATCRBS Signal Format for the BCAS Data Link,

Abstract

The evaluation of the integrity of the Air Traffic Control Radar Beacon System (ATCRBS) signal format for the Beacon Collision Avoidance System (BCAS) data link was based on measurements of the actual RF environment today, simulations of sophisticated signal processors, and basic calculations. The conclusions reached by the task force all relate to achieving a high integrity data link tailored to the BCAS application and were derived from tests run on the DABS ground-based reply processor-they are the following: (1) A data link with a high degree of error protection coding is essential. (2) Multiple transmissions - itself a form of coding - is essential. (3) A two-way data link is highly desirable from the point of view of the coordination logic. (Author)
