Analysis of AMS(R)S VHF Communication and Voice Communication Simulation Using Mathematical Programming Language

To expand the coverage of current aviation VHF communication services, it is necessary to develop a satellite-based system. This research aims analyze satellite link budget calculations for AMS(R)S frequencies using Low Earth Orbit (LEO) at an altitude 600 km, in accordance with studies conducted by ICAO and ITU. The calculation, parameters such as aircraft antenna gain = -1 dBi, 8 RF power 16 watts, 85 results receiver sensitivity between -107 dBm - 25.56 dB, well -93 38.65 dB. When simulating end-to-end (loopback: aircraft-satellite-aircraft 14.92 dB 14 Simulations were also carried out voice AWGN channel illustration Eb/No 10 resulting performance audio link.
