The BeiDou Navigation Satellite System (BDS) is a Chinese satellite navigation system. It consists of two separate satellite constellations – a limited test system that has been operating since 2000, and a full-scale global navigation system that is currently under construction.

Alternate mission URLs consolidate to this canonical launch record so exact mission timing, status, media, and source context stay on one page.
Use these internal paths to move from this exact launch record into the provider, vehicle, launch-site, schedule, and mission-family pages that own broader context.
This launch currently has no dedicated mission-family hub, so provider, vehicle, site, and canonical record links are the primary internal paths.
Some high-demand launch records carry specialized search intent. These profiles explain what can be verified from the published record without filling gaps that upstream sources have not published.
Navigation payload evidence is grouped from published launch, payload, orbit, program, and source-link records so the page can answer constellation, spacecraft, orbit, provider, and schedule intent without adding unpublished mission details.
Key structured fields for this launch record are grouped here so the page answers mission, payload, orbit, provider, source, and timing questions before the deeper tracking and media sections.
This record is preserved as historical launch context. The page emphasizes what was launched, the vehicle and pad involved, published outcome/status fields, linked programs, and source records instead of treating the mission like an upcoming countdown.

The Long March 3B is a Chinese orbital carrier rocket. Introduced in 1996, it is launched from Launch Area 2 and 3 at the Xichang Satellite Launch Center in Sichuan. A three-stage rocket with four strap-on liquid rocket boosters, it is currently the most powerful member of the Long March rocket family and the heaviest of the Long March 3 rocket family, and is mainly used to place communications satellites into geosynchronous orbits.
The China Aerospace Science and Technology Corporation (CASC) is the main contractor for the Chinese space program. It is state-owned and has a number of subordinate entities which design, develop and manufacture a range of spacecraft, launch vehicles, strategic and tactical missile systems, and ground equipment. It was officially established in July 1999 as part of a Chinese government reform drive, having previously been one part of the former China Aerospace Corporation. Various incarnations of the program date back to 1956.
