導(dǎo)語：中國“一箭雙星”成功發(fā)射兩顆北斗導(dǎo)航衛(wèi)星 首次裝載搜救設(shè)備

China successfully launched the 37th and 38th beidou navigation satellites at the xichang satellite launch center at 22:07 PM Beijing time with a long march-3b carrier rocket and an upper stage of yuanzheng 1, the China satellite navigation system management office said Monday.

The two satellites, belonging to the medium-circle earth orbit satellite, are the 13th and 14th networking satellites of China's beidou 3 global system. The two beidou navigation satellites are the first to be equipped with standard equipment from the international search and rescue organization, which will provide distress warning and positioning services to global users.

After more than three hours of flight, the two beidou satellites successfully entered the preset orbit, and the following tests and tests will be conducted and evaluated, and the network will be connected with the 12 beidou 3 global system navigation satellites previously launched to provide timely service. According to the plan, China will build a basic system consisting of 18 beidou 3 satellites by the end of this year to provide services to countries and regions along the "One Belt And One Road" line.
