  1. Architectures for next generation high throughput satellite systems

    This paper presents a model to estimate aggregate system capacity as a function of radio band, available spectrum, spot beams, waveforms, and payload capability comprising antenna size, power, and digital/analog connectivity across various links and availability objectives for next-generation high throughput satellite systems. This paper presents architectural building blocks for next-generation high throughput satellite systems using low earth, medium earth, and geosynchronous orbit satellite constellations, with and without onboard processing and inter-satellite links. This paper describes a system implementation approach using industry standards such as DVB-S2X and 4G LTE.

  2. Eutelsat HTS systems

    HTS systems are a breakthrough in satellite communications because they offer a considerable reduction in the service cost. This brings satellite communications closer to the consumer with costs and quality of service comparable with terrestrial services and on a ubiquitous basis.

  3. A novel routing design in the IP-based GEO/LEO hybrid satellite networks

    Zhaofeng Wu, Guyu Hu, Fenglin Jin, Yu Song, Yinjin Fu and Guiqiang Ni

    Article first published online: 13 JAN 2016 | DOI: 10.1002/sat.1174

    Based on the division of the Earth surface, the geostationary orbit/low earth orbit hybrid satellite network is able to achieve the separation of the user layer and the satellite segment along with the separation of the user identifier and locator, which greatly facilitates the user mobility management in the satellite networks. The proposed hop-constrained adaptive routing mechanism can then be applied to realize the load balancing in the low earth orbit satellite segment.

  4. A modified normalized min-sum algorithm for LDPC decoding using order statistics

    Wen Xue, Tian Ban and Jianxin Wang

    Article first published online: 11 JAN 2016 | DOI: 10.1002/sat.1173

    We propose a new modified normalized min-sum algorithm (NMSA) for low-density parity-check codes decoding. Two different modification factors are used to normalize the results of check node renew calculations. Simulation results show that the new modified NMSA achieves better bit error rate performance than NMSA without adding implementation complexity.

  5. DVB-S2X system performance results for broadcast and unicast broadband networks

    Article first published online: 6 JAN 2016 | DOI: 10.1002/sat.1168

    The extension of the Digital Video Broadcasting via Satellite Second Generation (DVB-S2) standard targeted the main satellite markets. In this paper, we present potential system performance improvements that can be achieved by deploying the techniques available from DVB-S2X in satellite broadcast (direct-to-home) as well as broadband networks (very small aperture terminal scenario). It is shown that the combination of DVB-S2X features offers significant advances and opportunities to service providers, particularly in emerging satellite systems such as multi-beam Ka-band broadband as well as broadcasting satellite networks.
