查询词典 synchronous satellite

The real-time system put forward here is a soft real-time system based on Windows NT. Preemptive multitasking mechanism is used on NT, in this way, the beyond-visual-range and real-time transmission of the TIS and command/control information can be realized via data link relayed by synchronous satellite.

实现的实时系统是一个基于Windows NT的弱实时系统，它通过在NT上采用多任务抢占机制以及同步卫星为中继的数据链路实现了TIS信息和指控信息的超视距实时传输，解决了信息的超视距实时传输问题。

This algorithm is applied in a typical sun-synchronous satellite, by using Spearman rank order correlation coefficient to compare the result with state-of-theart researches.

Kinds and selecting principle of phase shifter of the key devices in television receiving system of autotrackinging synchronous telecommunication satellite are analyzed. Transcendental equation of the propagation constant of latching ferrite phase shifter is derived, its properties are discussed.

分析了自动跟踪同步通信卫星电视接收系统中的关键元件移相器的分类及选取原则，推导了锁式铁氧体移相器传播常数的超越方程，并对它进行了详细地讨论。

The synchronous satellite is used to support some small bussinesses in the time with low business amount which nonsynchronous satellite can not cover like late at night and small hours,thus to insure the requirement of satellite communication of China with low investment cost.

本发明公开了一种中国综合卫星通信系统，它是由同步卫星和若干个非同步卫星构成，所述的非同步卫星是由中轨卫星或椭圆轨道卫星星座组成，具有区域性和时限性，即非同步卫星采用只在每天业务高峰期覆盖我国的时限区域性星座，在非同步卫星不能覆盖的低业务量时段如深夜和凌晨，可由同步卫星来支持这些小的业务量。

The other is Beidou satellite navigation system, which consists of two synchronous satellites working over the equator and the control system on the ground. Its advantage is that the overlaying region is wide.

该系统的优点是导航范围广，可以覆盖我国本土和邻近的区域，其缺点是采用&应答&工作方式，容易暴露目标，且用户容量有限。
