Multilateration techniques for positive aircraft location and identification

This paper presents the results of tests using Cardion´s Cooperative Area Precision Tracking System (CAPTS), The basic theory of operation of a multilateration system is explained. The ability of CAPTS to provide positive aircraft identity in order to put “tags” on ASDE radar displays is proved through presentation of test data. Data showing both theoretical and measured positional accuracy with test results showing the probability of correctly identifying targets is included. Test data is derived from recent demonstrations conducted at the FAATC in Atlantic City, NJ and the tests conducted at Hartsfield International Airport in Atlanta GA
