Satellite Communication 5, Followers. Papers People. Analysis and modeling of the cloud impairments of satellite-to-land mobile channel at Ku and Ka bands.
Cloud impairments have significant effect on signal propagated in the satellite to land stationary terminals channel at frequencies above 10 GHz. With the recent satellite to land mobile terminals network technologies and services that With the recent satellite to land mobile terminals network technologies and services that use these frequencies, there is a lack of channel impairments modeling and analysis for such type of link.
This study presents a reliable channel model of satellite-to-land mobile terminals that consider dynamic cloudy weather impairments. The model involves modules that design multipath signals, direct clear line-of-sight LOS normalized signals, and cloud impairments. Results show that a considerable change occurs in the performance of the signal propagated through research paper on satellite communication cloud. The change appears as deviations in the fade depth and the variance of the propagated signal in the link between the satellite and the land mobile terminals.
The channel model is a realistic approach to the link characteristics, which satellite systems designers should consider when designing high data rate satellite systems. Save to Library. AWACS Rising — Joint C2ISR, research paper on satellite communication, Force Multiplier for the 21st Century. A published article in the NATO Joint Air Power Competence Centre JAPCC Journal. The focus of the article is the transformation of the NATO E-3A Airborne Warning and Control System AWACSfrom a purely air centric surveillance and The focus of the article is the transformation of the NATO E-3A Airborne Warning and Control System AWACSfrom a purely air centric surveillance and control platform to an operational level battle management and intelligence, surveillance and reconnaissance ISR system.
The article explores the technical and operational requirements for the system and its aircrews to effectively support emerging mission roles and responsibilities. Lessons from the transformation process are applicable to civil capabilities undergoing major changes related to emerging technologies. Quantum Entanglement. The phenomenon of quantum entanglement involving two particles has puzzled us for a long time.
This article presents some possible solutions. A Lost Connection: Geostationary Satellite Networks And The International Telecommunication Union. Over the past forty years, communications and broadcasting via geostationary satellite systems have become integral and valued parts of the global information infrastructure.
International communications and data distribution from International communications and data distribution from orbit, however, have been hobbled by regulatory mechanisms administered under the auspices of the International Research paper on satellite communication Union.
The author examines the current regime and the problems confronting the industry, discusses potential solutions, and proposes that the present method for allocating frequencies and orbital positions for geostationary satellite networks can be substantially enhanced through an auction process and the addition of select regulatory changes.

Atmospheric condition variations were shown to have research paper on satellite communication major effect on the earth sky signal quality at Ku band. Moreover, such variations increased in the tropical regions as compared to temperate areas due to their different weather Moreover, such variations increased research paper on satellite communication the tropical regions as compared to temperate areas due to their different weather parameters. With the increase of recent satellite communication technology applications throughout the tropical countries and lack of information regarding the atmospheric impairments analysis, research paper on satellite communication, simulation and mitigation techniques, there is an ever increasing need for extracting a unique and accurate performance of the signal quality effects during highly natural tropical weather impairments.
This paper presents a new method developed for proper analysis with distinctive and highly realistic performance evaluation for signal quality during the atmospheric conditions variations in 14 tropical areas from the four continents analyzed based on actual measured parameters. The method implementation includes signal attenuation, carrier to noise ratio, symbol energy to noise ratio, and symbol error rate at different areas and different modulation schemes.
Furthermore, for improvement in analysis in terms of covering more remarkable regions in tropics, the paper provides new measurements data with analysis for certain region in tropics used as a test bed and to add measurement data of such area to the world's data base for future researchers.
The results show a significant investigation and performance observation in terms of weather impairments in tropical regions in general and each region in that area in particular regarding the signal attenuation and error rates accompanied for several transmission schemes.

Then we will show its advantages and disadvantages and a comparison with the one described in the TCP CUBIC protocol. Comparative performance evaluation of TCP Hybla and TCP Cubic for satellite communication under low error conditions.
Satellite communication has become important in the current global data communication due to its large coverage area, research paper on satellite communication. Satellite links are affected by two major concerns: long propagation delays, and relatively high error rates, research paper on satellite communication.
Standard TCP research paper on satellite communication control variants were not designed to address these challenges. They generally depend on round trip times RTTsand hence suffer heavily if the RTTs are large, research paper on satellite communication.
Various TCP variants like Hybla have been proposed in order to optimize the channel throughput in heterogeneous networks incorporating satellite links. The error rate of satellite channels can be substantially mitigated using forward error correction FEC techniques. In such a situation, according to the results obtained by our comparative study, the performance of Cubic, which is designed for high-speed networks, is better than Hybla, in conditions of high-latency and low error rates.
