“…For ensure permanent relays between ground stations and aircraft throughout the entire globe The use of satellite systems is required. To handle the increasing aircraft number, the International Civil Aviation Organization (ICAO) proposes a system of air traffic navigation reliable presented in Figure 1 [3], capacitive and global based on a concept called Communication Navigation Surveillance (CNS), a system of data link: Aeronautical Telecommunication Network (ATN). The current Air Traffic Management (ATM) procedures [4] are still based on VHF communications and claims for an improvement of ATM concepts.…”

Due to the satellite motion with respect to the earth' s surface and the aircraft's mobility, it is required to handover frequently in the process of communicating , In This paper ,assuming that the aircraft's location and speed can be determined , we proposes a suitable study for managing handover in satellite constellations for serving air traffic communication . The main objective of This study is selecting the best scheme which reduce significantly contact failure Probability ,this techniques are: non priority, priority, and queuing handoff schemes ,in this paper we are interested only in schemes that prioritize handover request in particular handoff queuing schemes. Channel allocation strategy (FCA) is employed, and the simulation results obtained concern: call blocking probability, handover failure probability, and average waiting time in the queue. Also simulation results are compared to choose the best one which reduces the contacts failureownership ratios. That supports more firm specific information is incorporated into stock prices as the ratio of foreign ownership increases.
