低轨道的 meaning in English

low orbit
low-orbit

The tdrss ( tracking and data relay satellite system ) is a system which can supply the data relay and tt & c ( telemetry tracking and command ) service for the aircraft which are low and middle earth orbit and other aircrafts , aircraft and earth station
跟踪与数据中继卫星系统tdrss ( trackinganddatarelaysatellitesystem )是为中、低轨道的航天器与航天器之间、航天器与地面站之间提供数据中继、连续跟踪与轨道测控服务的系统。
Such tdrss system can significantly reduce the use of ground - based monitors as well as increasing medium - low orbit coverage , hence enhance the efficiency of the usage of space along medium - low orbit . “ space target capturing and tracking ” ( stct ) is an important technique in data relay satellite system , and is the preliminary requirement to establish the space link . “ performance of analyzing and simulating on tracking receiver in data relay satellite capturing and tracking system ” plays an important role of stct
数据中继卫星系统是为中、低轨道的航天器与航天器之间、航天器与地面站之间提供数据中继、连续跟踪与轨道测控服务的系统,使用数据中继卫星可以大量减少地面测控站的数量,增大对中、低轨道的覆盖率,有效的利用中、低轨道资源。 “星间目标捕获与跟踪”是数据中继卫星系统的一项关键技术,是建立星间链路的首要条件。
