简介：法国市场是个高度竞争的市场，有两家卫星付费电视运营商——CanalSatellite公司和TPS公司。CanalSatellite公司不仅是法国，也是欧洲卫星付费电视领域中最强大的竞争者之一。据统计，CanalSatellite公司的用户增加较快，以2004年统计数据为例（2005年数据未统计出），到2004年6月30日的统计数据显示，用户数已接近290万户．其中在法国的用户增加近25万户；而TPS的状况令人担忧，在同一时期内增加不到8万户，还不到CanalSatellite的1／3。这两家运营商在法国市场上竞争是很激烈的。CanalSatellite公司此后宣布了其新的频道阵容．旨在保持对TPS公司的竞争优势。

简介：为使用高度重新分配改进导出卫星的大气的运动向量(AMV)的质量的一个方法被介绍。位于高度重新分配下面的基本原理被探索，并且技术细节被使用使用NCEP分析风的三个高度重新分配计划学习。AMV的质量通常被改进跟随重新分配，尽管改进的大小根据使用的计划不同。计划3提供最好的质量和稳定性，在计划1和计划2列在后面。在AMV的带的部件的否定偏爱减少从[5，4]ms1到<1ms1追随者重新分配。南方的部件也改善。AMV源于红外线并且水蒸汽隧道分别地在58.7%和25%改善。使用在AMV的运作的推导的计划3的可行性被合并T511中等范围的数字天气预言(NWP)预言的预报风领域学习系统。合并12-h预报在从水蒸汽隧道检索的南方的风中在带的风和积极偏爱中减少否定偏爱，改进在26.7%的AMV的全面质量。线性地扩大预报领域的有效性时期在检索AMV减少改进，但是这减小的大小是小的。合并120-h预报地仍然导致13%改进，尽管它可以消除好质量的很多AMV。
