Software Defined Satellite Networking (SDSN) provides an innovative perspective to manage satellite network through logically centralized network view and standard interfaces between the control and data plane. Significant advantages of SDSN include enabling integration of space and terrestrial network, flexible and efficient resource management, rapid and economical network function updating, etc...
To solve the phase deviation problem caused by antenna orientation centre deviation during the phase calibration of Monopulse tracking receiver on ship-borne sitcom station, a phase compensation method is proposed to enhance the phase calibration precision. The working principle of monopulse tracking receiver is discussed, the demodulation process of sum and difference signal, and the cause of phase...
There are some shortcomings in the delay tolerant network (DTN) routing algorithm, such as low message delivery rate, low network efficiency and high cost in the satellite network. In order to solve the problem above, this paper proposes a limited copy algorithm MPWLC based on service probability. In MPWLC, not only is the number of copies limited, but the storage resources of the satellite are also...
As in-line interference between geostationary(GEO) and Non-Geostationary(NGEO) systems is becoming more and more serious. We propose an efficient utilisation of the adaptive modulation and coding (AMC) scheme for spectral coexistence of GEO and NGEO satellites to mitigate in-line interference. Results of Simulation show that the proposed scheme can improve the performance of the NGEO system in comparison...
The current ship-shore communication is microwave communication, which is limited by transmission bandwidth and speed. So it is hard to satisfy the requirement of high-speed and stupendous-capacity in future. Within researching the development trend of optical communication, a communication mode based on optical communication is proposed to solve the problem. And considering the specialty of ship-shore...
To satisfy the TT&C and communication needs of aviation and aerospace flight vehicle, it is necessary to construct integrated Space-Air-Ground TT&C and Communication network with all-sided covering and flexible networking. The three-layered architecture of the integrated network is designed, and the composition, function and feature of each layer are discussed. By taking the advantages of...
The current satellite network design is approaching an inflection point with mobile devices as the primary enduser devices. In addition, identifier/location separation is commonly used to enhance mobility in future satellite networks. To this end, a key issue must be addressed is the design of rapid mapping resolution system. In this work, a design overview of a rapid mapping resolution system is...
