March 18 (Xinhua) — China’s homegrown BeiDou Navigation Satellite
System (BDS) has been operating smoothly and providing stable quality
services to global users since its official launch last summer.
According to the China Satellite Navigation Office (CSNO), the service capability of BDS is now first-class in the world.
China officially commissioned BDS on July 31, 2020, opening the new BDS-3 system to global users.
with positioning, navigation and timing services, the BDS system can
provide a variety of value-added services like global search and rescue
assistance, short message communication, ground- and satellite-based
augmentation, as well as precise point positioning.
BDS is serving diversified industries, generating profits for mass
consumer products and becoming increasingly integrated into people’s
on real-time test results, the BDS’s positioning, velocity measurement,
timing accuracy, and its service availability and continuity all meet
requirements, according to the CSNO.
The special functions of BDS, such as short message communication, have also been put into service, according to the office.
Both the regional and global short message communication services are now open to both the public and users in various fields.
example, its satellite-based augmentation function is now providing
trial services to users with high integrity requirements, such as those
in the civil aviation, maritime and railway sectors.
the high-precision single-point positioning function is being used in
such fields as precision agriculture, land survey and automatic driving.

SERVING CHINA AND WORLD
BDS is now serving the world, operating alongside three other systems:
GPS of the United States; Galileo of the European Union; and GLONASS of
China-developed chips, modules and other key technologies supporting
BDS have made comprehensive breakthroughs and been applied in
diversified industries, with performance indexes equivalent to global
peers. So far, the key BeiDou-related products have been exported to
more than 120 countries and regions.
As well as serving users across a variety of industries, BDS is generating profits in the field of mass consumer products.
China’s opening of the BDS to global users, major international
smartphone manufacturers, including Apple, have widely supported BeiDou.
In the fourth quarter of 2020, 79 percent of the smartphones in the
Chinese market had applied for network access to support BDS
October 2020, China and Russia agreed to increase the compatibility and
interoperability of their global satellite navigation systems to better
serve the two countries’ development, according to a recent report on
China’s aerospace industry.
BDS system is becoming ever more deeply integrated into people’s lives,
making use of progress in chip miniaturization, low power consumption,
low cost, radio frequency baseband integration and other technologies,
as well as the broad integration of satellite navigation IP cores and
mobile communications, said the CSNO.
BDS continues to generate new application scenarios and models, thanks
to Chinese researchers endowing the system with routine and specialized
the integration of platforms, data, technologies and terminals, the
integration of communication and navigation will be deepened and
realized. The regional short message service will be available in
smartphones within the year, realizing the integration of mobile
communication and short message communication without changing cards or
numbers nor adding additional peripherals.
The high-precision ground-based augmentation service of BDS has already empowered mobile phones with meter-level positioning.
the BDS as core, China plans to build a more ubiquitous, integrated and
intelligent positioning, navigation and timing system by 2035, and make
it a spatial and temporal information service infrastructure.
