With the successful launch of the fifth and sixth navigation satellites of the Beidou III, China's Beidou satellite navigation system entered the intensive launch phase of the global network. There are more and more "Beidou" in space, and how people on the ground should use it. What kind of precision is used has become a high-profile issue.
In a recent interview, the reporter learned that the first phase of the construction of China's Beidou ground-based augmentation system “National One Network†officially passed the acceptance test, providing sub-meter accurate positioning services nationwide and providing real-time in 21 provinces in China. Dynamic centimeter-level precision positioning service. The total number of users of the Beidou Satellite Chihiro location service platform exceeds 100 million, and the A-Beidou accelerated positioning service covers more than 200 countries and regions around the world.
The construction unit of the National Beidou Ground Augmentation System “National One Network†is a Chihiro Location Network Co., Ltd. jointly established by China Ordnance Industry Group and Alibaba Group. The company's CEO Chen Jinpei told reporters that the positioning error of the traditional satellite navigation system of 5 to 10 meters has long been unable to meet the needs of today's production and life. By providing high-precision positioning services, it will provide greater value to the whole society and become China's Beidou "curve overtaking" The important goal, especially in the robot era of the Internet of Everything, only the accurate positioning ability of the sub-meter or even centimeter can meet the needs of various IoT terminals.
To achieve this goal, the construction of the Beidou ground-based augmentation system is particularly important. "Under the influence of systemic factors such as satellite orbit error and satellite clock error, the error of traditional satellite navigation system is difficult to eliminate." The technical staff in the industry said that by establishing a ground-based enhancement station on the ground, the positioning algorithm obtains the differential information of the positioning data. A wide range of broadcasts can help all types of terminals achieve high-precision positioning.
On May 18, 2016, the National Beidou Ground Augmentation System was put into operation, marking the beginning of China Beidou to provide high-precision location services to the whole country. Today, the system has established more than 2,000 ground-based augmentation stations across the country, providing Internet users with big data operations to provide accurate positioning and extension services to users across the country.
Chen Jinpei revealed that this year, the national Beidou ground-based augmentation system will achieve full coverage of real-time centimeter-level services in mainland China.
At that time, Beidou high-precision positioning service is expected to become a public service shared by the whole society. Under its empowerment, smart city, autonomous driving, smart logistics and other applications will realize real large-scale commercial use. Chen Jinpei also said that in the next three years, more mobile phones, bicycles, wearable devices and other terminals will use Beidou high-precision positioning services to empower urban management and bring convenience to people's lives.
