Three different collision avoidance system CAS analyses were performed ground station clock requirement, Loran-C accuracy and comparisons, and CAS monitoring requirements. Cesium beam standards are evaluated to determine their time accuracy, the number required to attain and maintain time to within 0.5 microseconds, 3 sigma. The Loran-C system is reviewed to determine the potential time accuracy attainable by monitoring the Loran-C transmission. The results are then compared to the accuracy attainable from satellite, television, WWV and WWVB time transfer. The CAS equipment has certain built-in tests. These tests, as well as additional external monitors, are reviewed to categorize the test type and effectiveness.
