On the 19th  September 2024 schedule to launch  CNSA _China National Space Administration -China – People’s Republic of China 0904 Hours Hong Kong –Beijing Time China- People’s Republic of China…. at the Xichang Satellite Launch Center, Sichuan Province…..The Chang Zheng -Long March 3B carrier rocket ignited and took off from the Xichang Satellite Launch Center…..

Successfully launching the two Advance Geo Positioning Satellites Beidou number 59 and 60.. in which also preforms various other provisions of  Transportation, hydrological monitoring, meteorological forecasting… For more than 20 years, Beidou navigation satellites have been shining in the sky, providing satellite navigation services to the world. China will launch two Beidou navigation satellites….

This group of satellites is a medium earth orbit satellite. It is the first group of MEO satellites launched after the completion and opening of my country’s Beidou-3 global satellite navigation system. After entering orbit and completing on-orbit testing, it will be connected to the Beidou satellite navigation system.



Compared with the previous MEO network satellites, this group of satellites has further upgraded their functional performance in terms of global short message communication capacity, satellite-borne atomic clock technology, and payload intelligence. After being connected to the network, the reliability and service performance of the Beidou system will be further improved. , is of great significance to support the stable operation and large-scale application of the system, and lays the foundation for the design of the next generation of Beidou satellites.



The Beidou navigation satellite and supporting launch vehicle launched this time were jointly developed by the China Academy of Space Technology and the China Academy of Launch Vehicle Technology, both affiliated to China Aerospace Science and Technology Corporation.

On the 1st August 2024 schedule to launch  CNSA _China National Space Administration -China – People’s Republic of China 2114 Hours Hong Kong –Beijing Time China- People’s Republic of China…. at the Xichang Satellite Launch Center, Sichuan Province…..  at the No. 2 site of the Xichang Launch Center in China, the “Long March 3B” carrier rocket carrying the Satellite Internet High-orbit Satellite 02 was ignited and launched, and the satellite was sent to the geosynchronous transfer orbit (GTO).

The “passenger” of this mission, Satellite Internet High-orbit Satellite 02, was developed by the 5th Academy of China Aerospace Science and Technology Corporation and is the successor to Satellite Internet High-orbit Satellite 01.

The Long March 3B is a medium-sized liquid carrier rocket developed by the First Academy of China Aerospace Science and Technology Corporation, with a three-and-a-half-stage configuration. At present, the Long March 3B is in use in the enhanced version (CZ-3B/E), of which the modified version (CZ-3B/G2) is the most powerful model. The modified version 2 rocket is 56.326 meters long, with a maximum core stage diameter of 3.35 meters, a takeoff mass of 458.97 tons, and a maximum capacity of 5.55 tons for a standard geosynchronous transfer orbit (GTO). This launch mission was launched during the rainy season in Xichang. Based on the various waterproof designs of the rocket, the model team made full use of multiple protections such as anti-condensation air conditioning and moisture-proof sand, and took waterproof and moisture-proof measures.

This mission is the 97th launch of the Long March 3B rocket. Since the successful launch of the Long March 3B Yao 68 (68th) on June 23, 2020, the rocket has achieved 30 consecutive victories. In 2024, the Long March 3A series of rockets will once again enter a high-density launch period. So far this year, the Long March 3B has carried out 4 launch missions.

This launch is the 10th launch from the Xichang Launch Center in 2024, the 34th launch in China and the 138th launch in the world. At the same time, this launch is also the 529th launch of the “Long March” series of rockets.

On the 30th May 2024 in  CNSA _China National Space Administration -China – People’s Republic of China 2012 hours Hong Kong –Beijing Time China- People’s Republic of China launch the Chang Zheng Long March 3B carrier rocket successfully launched the Pakistan multi-mission communications satellite…..  Satellite at the Xichang Satellite Launch Center, Sichuan Province

At 20:12 on May 30, the Long March 3B carrier rocket ignited and took off from the Xichang Satellite Launch Center, and then successfully sent the Pakistan multi-mission communications satellite into the predetermined orbit. The launch mission was a complete success. The Pakistan multi-mission communications satellite was developed by the Fifth Academy of China Aerospace Science and Technology Corporation and uses the Dongfanghong-4 enhanced communications satellite platform.

Pakistan’s multi-mission communications satellite
① Dongfanghong-4 enhanced communications satellite platform
② Equipped with 9 antennas and 48 C, Ku, Ka, L and other multi-band transponders
③ Take-off weight 5,400 kg
④ Fixed in geosynchronous orbit 38.2 degrees east longitude
⑤ Service life 15 years



The satellite has a service life of 15 years and will be stationed above the equator at 38.2 degrees east longitude in the geosynchronous orbit, covering Pakistan and surrounding areas. After in-orbit operation, the satellite will provide users in the region with a variety of services such as television, radio, regional enhanced communications, high-throughput broadband, and satellite-based enhanced navigation. The Long March 3B carrier rocket was developed by the First Academy of China Aerospace Science and Technology Corporation. This launch is the 524th launch of the Long March series of carrier rockets…
