Description

特别是用于非同步卫星指向的天线系统
发明的领域是天线系统，特别适用于移动卫星指向的天线系统。更精确地说，本发明涉及一个至少有两个天线的系统，这些天线能够在一个立体角度的任意方向上独立地指向。
在本发明的范围内，我们考虑地面传输系统，它被安置在例如固定的楼顶。该系统包括至少两个例如抛物面的天线，用于与非同步卫星进行发射和/或接收通信。这些天线由于体积，和/或为减小与单一的调制解调器的连接长度，和/或为能够置于同一保护罩中而相互位置临近(也就是说共位(co-loca1isées)的)。两个天线在方位角和高度方向上独立地指向，也就是说每一个被安装在分开的支撑上。
该系统所提出的问题是，根据卫星的位置，并且特别是当它们的仰角很小的时候，一个天线可能会遮蔽另一个天线，如同图1和2上所示的。我们考虑到天线是被置于同一水平面内，也就是说它们是同样的高度。
图1是两个共位抛物面天线系统的顶视简图，在图上，两天线11和12在相对的方向上指向，并且它们的任何一个都不能发射或接收信号，屏蔽是相互的。在图2上，天线10和11在同一方向上指向，并且天线11屏蔽天线10。
为避免该屏蔽，可以将天线间的距离拉远，但是在这种情况下，紧凑的需要就不能被满足了。另外，它们也不能再受到公用天线罩的保护了。
本发明的目的就是在于克服这些缺陷。
更准确地说，本发明的目的之一是提供一种天线系统，它包括至少两个天线，每个天线能够在一个立体角度的任意方向上独立地指向，该系统允许天线共位而永远不会引起一个天线相对于另一个的屏蔽。
该目的，以及后面所提到的其他目的将由该天线系统所达到，它包括至少两个天线，每个天线能够在一个立体角度的任意方向上独立地指向，该系统的特征在于天线被安装于共同支撑上，该支撑与该支撑的旋转装置协同工作，旋转装置活动以避免一个天线相对于另一个天线屏蔽。
该共同支撑的旋转在天线对准同一方向或相对方向上时，特别是能够使得天线相互临近安置。
所使用的天线尤其可以是圆形或椭圆形抛物面天线，也就是说由天线补片所实现的有源天线或无源天线。
旋转装置最好用于执行相对于中间位置±45°的旋转。
天线系统最好由一个天线罩所覆盖，而发明特别是用于跟踪非同步卫星。
发明的其他特点和优点将根据对一个最佳实施例的描述以及附图而显现出来，实施例仅是用于说明但发明并不仅限于此，在附图中：
图1和2是两个共位抛物面天线系统的顶视简图；
图3表示了一个根据本发明的天线系统；
图4是根据发明包括椭圆天线的天线系统的顶视简图。
图1和2已经在前面参照背景技术进行了描述。
图3表示了一个根据发明的天线系统。在这里是两个圆形抛物面天线(10和11)。每一个天线被安置在一个支撑上，并且能够借助于俯仰定位装置12，13(例如每一个能够使天线相对于它进行±90°的俯仰旋转)和方位定位装置14，15(例如每一个能够使天线相对于它进行±180°的方位旋转)在任意一个立体角方向上独立指向。安置有公用发射/接收装置16连接到天线10和11上。
根据发明，天线10和11被安置在共同支撑17上，该共同支撑17的旋转装置18与支撑协同工作。更准确地说，天线10和11的方位定位装置14，15在这里被安装在共同支撑17上。为避免一个天线相对于另一个屏蔽，旋转装置18被激励。该旋转装置包括例如一个直接连接于轴19的马达，该轴固定于共同支撑17上。在假定将来一个天线相对于另一个比较拘束的情况下，共同支撑17的旋转相对于一中间位置能进行例如至少±45°。该假定可基于星历表的分析或基于来自天线10和11位置编码器的数据。因此我们总是可以自动保证一个天线相对于另一个不出现屏蔽，而不论是指向基本上相对的方向(图1)或基本上相同的方向(图2)。
这些天线同样可以由有源天线构成。
发明尤其是允许将天线系统置于同一保护天线罩20之下，该天线罩因此具有较小的体积。
为更加限制根据发明的天线系统的体积，天线还可以具有卵形或椭圆形的形状，比如图4所表示的。该图是根据发明的天线系统的顶视简图，所表示为21和22的天线被置于指向天顶的天线罩20内。天线21和22的表面与天线10和11的一样，以具有同样的性能。因此天线罩20相对于图3的天线罩具有更小的体积(大约20％)。
发明特别是用于，但并不排斥性地，用于非同步卫星的追踪。
