XICHANG, Nov. 19 (Xinhua) -- China sent two new satellites of the BeiDou Navigation Satellite System (BDS) into space on a Long March-3B carrier rocket from the Xichang Satellite Launch Center in Sichuan Province at 2:07 a.m. Monday.
The satellites entered a medium earth orbit more than three hours later and will work with 17 other BDS-3 satellites already in space. They are also the 42nd and 43rd satellites of the BDS satellite family.
With the successful launch, the basic BDS constellation deployment is complete. China plans to provide navigation services with the BDS-3 to the Belt and Road partner countries by the end of this year, marking a key step toward a global navigation service.

This is the lanch of No.18 and No.19 Satellites of Beidou Type III as I checked the title of the video
But thanks for sharing very inspiring!

Beidou 3M Launch

China orbited two more Beidou 3M navigation satellites on November 18, 2018. A Chang Zheng 3B (CZ-3B) launched the satellites, Beidou 3M-17 and 3M-18, from Xichang Satellite Launch Center with an 18:07 UTC liftoff from LC 3.

The CZ-3B liquid hydrogen fueled third stage fired twice to inject the vehicle into a transfer orbit. A hypergolic propellant Yuanzheng 1 (YZ-1) upper stage then fired its low thrust UDMH/N2O4 engine at apogee to insert the roughly 1.014 tonne satellites into their final, roughly 22,000 km x 55 deg orbits about four hours after liftoff.

The Beidou 3M series offers improved navigation accuracy compared to previous Beidou constellations. Plans call for 18 Beidou 3 satellites to be orbited by the end of 2018 and more than 30 by 2020.

It was the 8th CZ-3B/YZ-1 launch from XiChang with Beidou 3M satellites this year. A ninth CZ-3B orbited a Beidou 3G1 satellite. The launches have orbited 17 satellites.

The satellites entered a medium earth orbit more than three hours later and will work with 17 other BDS-3 satellites already in space. They are also the 42nd and 43rd satellites of the BDS satellite family.

With the successful launch, the basic BDS constellation deployment is complete. China plans to provide navigation services with the BDS-3 to countries participating in the Belt and Road Initiative by the end of this year.

"This is a key step for BDS developing from a domestic experimental system to a regional and then a global navigation system," said Yang Changfeng, chief designer of the BeiDou system.

The positioning accuracy of the BDS-3 system has been improved to 2.5 meters to 5 meters, up to twice as high as the BDS-2 system, said Yang.

Named after the Chinese term for the Big Dipper constellation, the BeiDou system started serving China in 2000 and the Asia-Pacific region in 2012.

China plans to launch another six BDS-3 satellites to the medium earth orbits, three satellites to the inclined geosynchronous earth orbit and two satellites to the geostationary earth orbit from 2019 to 2020.

The system will provide first-class services around the globe by the end of 2020.
