On 27 December, the China Satellite Navigation Office announced that global services had been provided and would start immediately.

The Navigation Office’s Director General stated that the third generation of the BeiDou Navigation Satellite System (BDS-3) ‘is completed, and the global services are provided starting today.’

The DG explained that development commenced in the 1990s and that, on 27 December 2012, BDS started to provide services to the Asia-Pacific region.

He added that 2018 had been an extraordinary year in BDS history:
- Firstly, intensive constellation deployment has resulted in the global service capability, with the launch of 19 satellites on 10 rockets in one year - a record in the history of the development of GNSS.
- Secondly, highly reliable operations have maintained  services in the Asia-Pacific region, with back-up satellites developed and launched, orbit control strategies refined, the ground system highly stable and the service provided stable and rising.
- Thirdly, there has been much international cooperation, with China hosting the UN International Ctee on GNSS and signing an inter-governmental agreement on China-Russian satellite navigation cooperation.
- Fourthly, sales of products such as BDS chips and modules exceeded 70 million pieces, with BDS high-precision products exported to over 90 countries.

On 27 December, the Office also released a series of documents, including a new (version 2.0) BDS Open Service Performance Standard. After global testing and evaluation, BDS service performance standards are quoted as:

- System service coverage: global  
- Positioning accuracy (95%): 10 m hor and 10 m vert
- Velocity accuracy (95%): 0.2 m/s
- Timing accuracy (95%): 20 ns
- System service availability: >95%

In the Asia-Pacific region, 95% positioning accuracy is 5 m horizontally and vertically.
