If you’re a wumao, you have to praise China even if only 72% of the world congratulated China for setting up Beidou ๐Ÿค—


Global Navigation Satellite System (GNSS)

A satellite system with global coverage is termed a Global Navigation Satellite System (GNSS). Current GNSSs include the Global Positioning System (GPS) developed by the United States, the Global Navigation Satellite System (GLONASS) operated by Russia and the BeiDou Navigation Satellite System (BDS), which was launched by China in June 2020, and the European Unionโ€™s Galileo. The first mentioned has been widely used internationally for years. We now see quite a few differences between the four existing GNSS systems.

GPS was the earliest satellite system project, started by the US Department of Defense in 1973. The first prototype spacecraft was launched in 1978 and the full constellation became operational in 1993. The system offered global services from 1994…

GLONASS is the second navigational system with global coverage. The Soviet Union commenced its GLONASS project in 1976 and launched its first satellite in 1982. GLONASS has gone through three generations (GLONASS, GLONASS-M, GLONASS-K) and the third generation is not yet finished. Russiaโ€™s navigation system achieved full global coverage with 24 satellites in 1995. Restoration of the system was made in 2011 after a decline in capacity.

Similarly, Chinaโ€™s BeiDou experienced three phases of construction with the third phase fully deployed in July 2020…Unlike GPS, which started working after being fully set, BeiDouโ€™s staged strategy made early commercial use of the system accessible. Besides, experience gained in the second phase led scientists to make a better design for BeiDou-3. The third step of BeiDou was launched in 2015 with full global coverage, using a total of 35 satellites.

The last GNSS is Galileo. Though the conception was agreed by the European Union and the European Space Agency in early 2002 and the first experimental satellite GIOVE-A was launched in 2005, it was not until 2011 that the first operational satellites were put into the constellation. Galileo has been offering Early Operational Capacity in 2016 and the complete 30-satellite system is expected by the end of 2020.

*What you read is not necessarily untrue but it’s written as propaganda to make all “Chinese peoples” so proud of China: “Love me China!”


๐Ÿ‡จ๐Ÿ‡ณ๐Ÿค๐Ÿป๐Ÿ’๐Ÿ‘๐ŸปMore than 140 countries & regions around the world sent congratulations to China:

China Beidou has officially & successfully run it’s own network.

China no longer uses U.S. Internet & it is no longer controlled by United States. Hence China can save a rental fees of 1000000000000000 yuan each year. The whole world will pay fees to China for the use of Beidou network, which will earn tens of trillion yuans in lease fees. Chinese peoples are proud of it.

Celebrate &
Cheers !!
A giant leap for the Chinese dream came true !
Love me Chinaโ€ฆ


The BeiDou Navigation Satellite System (BDS) (Chinese: ๅŒ—ๆ–—ๅซๆ˜Ÿๅฏผ่ˆช็ณป็ปŸ; pinyin: Bฤ›idว’u Wรจixฤซng DวŽohรกng Xรฌtว’ng [pรจitรฒu wรชiษ•รญล‹ tร uxวŽล‹ ษ•รฎtสฐสŠฬ€ล‹]) is a Chinese satellite navigation system. It consists of two separate satellite constellations. The first BeiDou system, officially called the BeiDou Satellite Navigation Experimental System and also known as BeiDou-1, consisted of three satellites which, beginning in 2000, offered limited coverage and navigation services, mainly for users in China and neighboring regions. BeiDou-1 was decommissioned at the end of 2012. On 23 June 2020, the final BeiDou satellite was successfully launched, the launch of the 55th satellite in the Beidou family. The third iteration of the Beidou Navigation Satellite System provides for global coverage for timing and navigation, offering an alternative to Russia’s GLONASS, the European Galileo positioning system, and America’s GPS.

The second generation of the system, officially called the BeiDou Navigation Satellite System (BDS) and also known as COMPASS or BeiDou-2, became operational in China in December 2011 with a partial constellation of 10 satellites in orbit.[4] Since December 2012, it has been offering services to customers in the Asia-Pacific region.[5]

In 2015, China launched the third generation BeiDou system (BeiDou-3) for global coverage. The first BDS-3 satellite was launched on 30 March 2015.[6] On 27 December 2018, BeiDou Navigation Satellite System started providing global services.[7][8] The 35th and the final satellite of BDS-3 was launched into orbit on 23 June 2020.[9] It was said in 2016 that BeiDou-3 will reach millimeter-level accuracy (with post-processing).[10]

According to China Daily, in 2015, fifteen years after the satellite system was launched, it was generating a turnover of $31.5 billion per annum for major companies such as China Aerospace Science and Industry Corporation, AutoNavi Holdings Ltd., and China North Industries Group Corp.[11] The industry has grown an average of over 20% in value annually to reach $64 billion in 2020 according to Xinhua citing data.[12][13]

Domestic industry reports forecast the satellite navigation service market output value, directly generated and driven by the Beidou system, will be worth 1 trillion yuan ($156.22 billion) by 2025, and $467 billion by 2035.[14][15]
