XICHANG, Sept. 19 (Xinhua) -- China on Thursday launched two new satellites for the BeiDou-3 Navigation Satellite System (BDS-3) from the Xichang Satellite Launch Center in southwest China's Sichuan Province.

The two satellites, the 59th and 60th satellites of the BeiDou family, were launched at 9:14 a.m. (Beijing Time) by a Long March-3B carrier rocket and the Yuanzheng-1 (Expedition-1) upper stage attached to the carrier rocket.

They are the second group of medium Earth orbit (MEO) satellites launched since BDS-3 was formally commissioned to provide satellite navigation services worldwide. After entering orbit and completing in-orbit tests, they will be connected to the BDS system.

孙继海在行业内的口碑以及实际行动，已经吸引了各方关注，这让孙继海也成功的进入到了足协视野。来自辽宁省足协的官方消息，孙继海当选辽宁足协的副主席，正式开启了自己在足协任职的新生涯。当然孙继海的主要精力还是放在青训上，他在辽宁足协也将主要管理青训方面的工作。此次也是辽宁足协更名、换届之际，孙继海等9人当选足协副主席，王亮成为秘书长。

Compared with the previous group of MEO satellites, these new satellites feature upgraded onboard atomic clocks and new inter-satellite link terminals.

They will further improve the reliability of the BDS-3 system and the performance of its positioning, navigation and timing (PNT), global short message communications and other services.

The satellites will also be used for new technology tests for the next generation BDS system, according to the China Satellite Navigation Office.

China will accelerate the construction and development of the next-generation BDS system, and increase technical research on a variety of PNT methods that do not rely on satellites, said the office.

The satellites and launch vehicles were respectively developed by the Innovation Academy for Microsatellites under the Chinese Academy of Sciences and the China Academy of Launch Vehicle Technology under the China Aerospace Science and Technology Corporation.

This launch was the 535th mission involving Long March series carrier rockets.  ■加拿大pc28神策预测
