双语新闻：中国计划向月球轨道发射两颗试验卫星

China plans to launch test satellites for communication technology named Tiandu-1 and Tiandu-2, according to the Deep Space Exploration Laboratory on Feb. 4.

2月4日，据深空探测实验室消息，我国计划发射名为“天都一号”和“天都二号”的通导技术试验卫星。

China plans to launch two test satellites into a lunar orbit to establish a communication between the Moon and the Earth.

中国计划向月球轨道发射两颗测试卫星，以建立月球和地球之间的通信。

The twin satellites will help to validate new technologies for navigation and signal transmissions.

这两颗卫星将有助于验证导航和信号传输的新技术。

It is reported that "Tiandu-1" and "Tiandu-2" two stars will enter the Earth-moon transfer orbit together with the Queqiao No. 2 lunar relay satellite, after which the two stars will perform near-moon braking and enter the large elliptical orbit around the moon, in the large elliptical orbit around the moon, using satellite-ground laser ranging, inter-satellite microwave ranging and other ways to carry out high-precision lunar orbit determination orbit technology verification." Chen Xiao, commander of the Sky navigation technology test star of the deep space exploration Laboratory, said that the two small and micro test satellites will provide a strong reference and basis for the subsequent establishment of the magqueqiao navigation remote integrated constellation system.

据悉，“‘天都一号’‘天都二号’两颗星将随鹊桥二号月球中继卫星一同进入地月转移轨道，之后两颗星将进行近月制动，进入环月大椭圆轨道，在环月大椭圆轨道上，采用星地激光测距、星间微波测距等方式，开展高精度月球轨道测定轨技术验证。”深空探测实验室天都通导技术试验星总指挥陈晓介绍，这两颗小微型试验卫星将为后续我国鹊桥通导遥综合星座系统的建立，提供有力的参考和依据。
