Abstract: Receiver Autonomous Integrity Monitoring (RAIM) is a method to monitor the integrity of GPS satellites by measuring the redundant satellites on the users receiver. In the very near future every GPS equipment used in the CNS system in the Indonesian ATM is required to
provide RAIM feature in order to improve the accuracy, integrity, continuity of service and availability of GPS. RAIM is able to inform ATM relating to Fault Detection and Fault Detection and Exclusion. This paper describes research undertaken by the GPS Group in BPPT to provide RAIM information to the users of Indonesian Airspace. The research concentrates in three sectors: signal in space, RAIM, and NoticeToAirMan (NOTAM) interface. This research is still in the preliminary phase of gathering information regarding the Asia/Pacific future development of CNS/ATM, measured propagation characteristic of GPS signal in Indonesian region and RAIM information. This paper presents the results of the preliminary phase research.
