Applications of the method in optimizing arrangement of antennas in small satellite platforms are investigated. Satellite antenna layout EMC simulation modeling, analysis and design optimization has been described in the article. Taking a LEO satellite prototype, we have established a satellite simulation model simulation model and the respective antennas, and calculate the degree of coupling b...

A number of satellite communication systems have been proposed using geosynchronous (GEO) satellites, medium earth orbit (MEO) and low earth orbit (LEO) constellations operating in the Ka-band and above. The next generation broadband satellite systems will use fast packet switching with onboard processing to provide full two-way services to and from earth stations. New services gaining momentum...

The integration of satellite and terrestrial networks is a promising solution for extending broadband coverage to areas not connected to a terrestrial infrastructure, as also demonstrated by recent commercial and standardisation endeavours. However, the large delays and Doppler shifts over the satellite channel pose severe technical challenges to traditional terrestrial systems, as LTE or 5G. I...

We study the problem of carrying voice calls over a LEO satellite network, and we present an analytical model for computing call blocking probabilities for a single orbit of a satellite constellation. We have devised a method to solve the corresponding Markov process eÆciently for up to 5-satellite orbits. For orbits consisting of a larger number of satellites, we have developed an approximate ...

This paper investigates a low-Earth orbit (LEO) satellite downlink for high-speed data communication in interference situations. A choke ring horn type antenna is used as the transmitting with an isoflux pattern LEO satellite, which has beam coverage of ±51.6° and bore-sight gain 4.4 dBi at 8 GHz. The receiving on ground station parabolic diameter 11.3 m, it half-power width (HPBW) 0.2° maximum...
