The BeiDou Navigation Satellite System (BDS) is a Chinese satellite navigation system.
, the United States' Global Positioning System (GPS) and Russia's Global Navigation Satellite System (GLONASS) are fully operational GNSSs, with China's BeiDou Navigation Satellite System (BDS) and the European Union's Galileo scheduled to be fully operational by 2020.

GLONASS

Global Navigation Satellite SystemGLONASS GPSGLONASS K
When fully completed, BeiDou will provide an alternative global navigation satellite system to the United States owned Global Positioning System (GPS), the Russian GLONASS or European Galileo systems and is expected to be more accurate than these.
Binary offset carrier (BOC) is the modulation used by Galileo, modernized GPS, and BeiDou-2.

Chen Fangyun

Considered the founder of radio electronics in China, he was pivotal in the development of telemetry, tracking and command (TT&C) systems that control China's satellites and missiles, and in the early development of the BeiDou satellite navigation system.

Galileo (satellite navigation)

GalileoGalileo positioning systemGalileo project
When fully completed, BeiDou will provide an alternative global navigation satellite system to the United States owned Global Positioning System (GPS), the Russian GLONASS or European Galileo systems and is expected to be more accurate than these. In September 2003, China intended to join the European Galileo positioning system project and was to invest €230 million (USD296 million, GBP160 million) in Galileo over the next few years.
The system is intended primarily for civilian use, unlike the more military-oriented systems of the United States (GPS), Russia (GLONASS), and China (BeiDou-1/2).

Global Positioning System

When fully completed, BeiDou will provide an alternative global navigation satellite system to the United States owned Global Positioning System (GPS), the Russian GLONASS or European Galileo systems and is expected to be more accurate than these.
GLONASS can be added to GPS devices, making more satellites available and enabling positions to be fixed more quickly and accurately, to within 2 m. China's BeiDou Navigation Satellite System began global services in 2018, with full deployment scheduled for 2020.

Long March 3C

On 15 January 2010, the official website of the BeiDou Navigation Satellite System went online, and the system's third satellite (Compass-G1) was carried into its orbit by a Long March 3C rocket on 17 January 2010.
The second carried the Compass-G2 navigation satellite, and was conducted on 14 April 2009.

According to Sun Jiadong, the chief designer of the navigation system, "Many organizations have been using our system for a while, and they like it very much."
He was also the chief designer of a second generation of special application satellites, such as communication, meteorological, and earth resource detecting satellites, as well as the Beidou-2 navigation system.

Long March 3B

On July 25, 2015, the 18th and 19th satellites were successfully launched from the Xichang Satellite Launch Center, marking the first time for China to launch two satellites at once on top of a Long March 3B/Expedition-1 carrier rocket.
Since 2015, the Long March 3B and 3C can optionally accommodate a YZ-1 upper stage, which has been used to carry dual launches or BeiDou navigation satellites into medium-Earth orbit.

People's Liberation Army

To date, the military service has been granted only to the People's Liberation Army and to the Pakistan Armed Forces.
The PLA has deployed a number of space-based systems for military purposes, including the imagery intelligence satellite systems like the ZiYan series, and the militarily designated JianBing series, synthetic aperture satellites (SAR) such as JianBing-5, BeiDou satellite navigation network, and secured communication satellites with FENGHUO-1.

Septentrio

Septentrio
The knowledge of the codes allowed a group of engineers at Septentrio to build the COMPASS receiver and report tracking and multipath characteristics of the “I” signals on E2 and E5B.
Septentrio’s receivers were used to track experimental Galileo signals transmitted by the GIOVE-A satellite and were also the first to track the signals of the first experimental satellite of the future Chinese Compass navigation system.

China

China is developing its own satellite navigation system, dubbed Beidou, which began offering commercial navigation services across Asia in 2012 and it started providing global services by the end of 2018.

Geosynchronous orbit

The new system will be a constellation of 35 satellites, which include 5 geostationary orbit satellites for backward compatibility with BeiDou-1, and 30 non-geostationary satellites (27 in medium Earth orbit and 3 in inclined geosynchronous orbit), that will offer complete coverage of the globe.
The Chinese BeiDou GNSS constellation uses five satellites in a geosynchronous orbit.
