Ka-band Tracking VSAT Antenna for Satellite Communications on the Move

过去一年，发射了几颗新一代Ka波段卫星（包括欧洲的Avanti的Hylas和Eutelsat的Ka-Sat），大大增加了目前地面系统覆盖范围以外地区宽带用户的能力。这些卫星是全球Ka波段可用性趋势的一部分，约有60颗Kaband卫星已经在轨道上或计划在2014年之前发射。除了提升这将给卫星提供的宽带部门，这也代表了移动的卫星通信部门的一个重要机会，总部位于英国的移动卫星提供商Inmarsat已经参与了Ka-多年来，Hollycroft Associates一直积极参与欧洲高速列车卫星宽带的开发，已经确定了对低成本、高吞吐量终端的需求，该终端用于移动的环境中，可以利用较低成本的Ka频带容量的可用性。到目前为止，在商业市场上还没有这样的终端，因此Hollycroft Associates建议开发一个完整的终端设计，该设计利用了英国现有的各个子系统的能力，并且可以很容易地开发成商业产品。这将重建英国的卫星终端能力，为移动的地面终端部门的出口开辟机会。我们已经进行了为期三个月的简短可行性研究，并确定了一小批英国公司，它们可以在供应链中合作，将适当的产品推向市场。虽然Hollycroft Associates和这些公司将提供一些内部开发资金，但也需要一些外部资金，因此市场证明是确保外部资金的重要下一步。

The past year has seen the launch of several new-generation Ka-band satellites (includingAvanti's Hylas and Eutelsat's Ka-Sat in Europe) which provide a significant increase incapacity for broadband users in regions beyond the reach of current terrestrial systems. Thesesatellites are part of a trend towards the availability of Ka-band globally, with some 60 Kabandsatellites either already in orbit or scheduled to be launched by 2014.In addition to the uplift this will give to the satellite delivered broadband sector this alsorepresents a significant opportunity for the mobile satcom sector, and UK-based mobilesatellite provider Inmarsat is already involved in the procurement of a fleet of Ka-bandsatellites for mobile use.For some years Hollycroft Associates has been actively involved in the development ofsatellite delivered broadband to high speed trains in Europe and has identified the need for alow-cost, high-throughput terminal for use in a mobile environment that can take advantage ofthe availability of lower cost Ka-band capacity. As yet there are no such terminals available inthe commercial market and consequently Hollycroft Associates proposes to develop acomplete terminal design which draws on individual subsystem capabilities available in theUK and which could be readily developed into a commercial product. This would re-establisha UK satellite terminal capability, opening up opportunities for export in the mobile groundterminal sector.We have already undertaken a brief three-month feasibility study and have identified a smallgroup of UK companies that could work together in the supply chain to bring an appropriateproduct to market. Whilst some internal development funding will be available fromHollycroft Associates and from these companies, there would also be a need for some externalfunding and thus a proof of market is the essential next step in securing this external funding.
