同步通信卫星

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。

Upon its first launch into geosynchronous orbit, WGS Flight 1 will become the U.S. Department of Defense's highest capacity communication satellite.

在该卫星首次进入地球同步轨道后，WGS飞行1号卫星将成为美国国防部的最高容量通信卫星。

The Saturn V would be necessary to take it to polar orbit, or sun-synchronous orbit (neither of which has yet been achieved by any manned spacecraft), and even to the geosynchronous orbit of Syncom 3, a communications satellite not quite in geostationary orbit.

土星五是要以它为极地轨道或太阳同步轨道(既不是至今尚未取得任何载人航天器)，甚至威胁到地球同步转移轨道的syncom3号通信卫星不甚静止轨道。
