The BDSs distinctive short message function has cilitated the power data collection in remote areas with no communication signal coverage. In 2008, when a magnitude-8 earthquake struck Wenchuan in southwest Chinas Sichuan Province, severely damaging ground communication cilities, rescuers used the short message function of BDS to report the locations of the quake-hit areas.
Extensively applied in various aspects of the national economy and peoples lives, BDS currently provides full-scale services in sectors ranging from transportation, public security, disaster relief, and mitigation to agriculture, forestry, and city management.
Despite being affected by three typhoons and the COVID-19 epidemic, Song Jilins 20 hectares of rice on the Qixing rm, northeast Chinas Heilongjiang Province, embraced a bumper harvest this year.
The application in precision agriculture is an example of how BDS has become a powerful impetus to boosting Chinas economic and social development and improving peoples living conditions.
On the Qixing rm, a combine harvester guided by the BDS is shuttling between the rice fields. Zhang Jinghui, another major rice planter, said with advanced navigation technology, the harvester can work precisely with an error range of less than 2 cm. It can also work during the night to increase efficiency.
When China was building the two makeshift hospitals of Huoshenshan and Leishenshan in Wuhan, once the epicenter of the COVID-19 epidemic in the country, equipment based on BDS provided high-precision positioning services and accelerated the construction.
Over the past 10 years, the total output value of Chinas satellite navigation and location service industry has increased by more than 20 percent annually. The output value reached 345 billion yuan (about 49.5 billion U.S. dollars) in 2022 and was expected to exceed 400 billion yuan in 2022.
During the construction of the Beijing-Xiongan intercity railway, a key project for the coordinated development of the Beijing-Tianjin-Hebei region, BDS has been applied to guide the track-laying work to make the railway safer and more comfortable.
The integration of BDS with emerging technologies, including 5G, mobile communications, and big data will be further promoted to create new business models and growth points, said BDS Spokesperson Ran Chengqi.
BDS was used for high-precision railway construction and management. BDS-based modules were installed on the trains traveling along the Qinghai-Tibet Railway to track accurate three-dimensional coordinates and running speed. Based on this information, the control center can optimize route planning, shorten train departure intervals and improve train operation efficiency and safety.
BDS not only belongs to China but to the whole world. By the end of 2022, China had exported its BDS-based products to more than 120 countries and regions. BDS has entered a new era of global service, benefiting precision rming, digital development, and smart port construction in ASEAN, South Asia, Eastern Europe, West Asia, and Africa.
BDS has played an indispensable part in helping fishermen cut losses and evade the strong winds and waves during typhoon season in Fujian Province.
The application of BDS has no boundaries, and more efforts will be made to develop new satellite navigation technologies to provide better navigation, positioning, and timing services for humankind, said Xie Jun, chief designer of the BDS-3 satellite system.
There was a lack of hands during the spring plowing season because of the epidemic, but the unmanned rice transplanters equipped with Chinas BeiDou Navigation Satellite System (BDS) helped out, Song said.
