Beidou precision spatio-temporal information empowers intelligent industry
With the rapid progress of science and technology, human society has gradually developed and evolved in the direction of intelligent society and intelligent society. The technological innovation of 5G has enabled our society to move from the Internet era to the Internet of Things era; and Beidou precision spatio-temporal information has empowered intelligent industries, and big data has basic spatio-temporal attributes, giving birth to intelligent applications; big data, AI computing and data twins have given machines the possibility of self-learning, and our world has become more and more intelligent.
With the development of satellite positioning technology, we have entered the era of electronic map navigation from the early era of paper maps, which has brought great convenience to car travel. However, due to the low GPS positioning accuracy, the positioning accuracy of 5-10 meters requires the judgment of auxiliary people to reach the destination. As the most important industrial carrier of intelligent society, cars are becoming more and more intelligent, in the process of continuous exploration and development of assisted driving and automatic driving, centimeter-level or even millimeter-level high-precision positioning has become an essential skill for cars, and at the same time, in the process of on-board navigation, it is also necessary to continuously adapt to the complex environment of satellite obstruction such as elevated highways, tunnels, and underground parking lots.
Beidou high-precision positioning technology provides a perfect solution for intelligent networked vehicles, and further improves the overall availability and safety through the integration of relative positioning technologies such as lidar positioning and visual positioning, and provides core basic services for all aspects of the supply chain. Beidou precision spatio-temporal service system, coupled with the automotive application ecosystem, has built a complete ecology of intelligent networked vehicle Beidou high-precision services.
Focus on Beidou chip design, high-precision position services
Mengxin technology products are widely used in many fields
Mengxin Technology is a high-tech enterprise specializing in Beidou chip design and high-precision location services. The company is located in the national high-tech industrial development zone, Wuhan Optics Valley. The company's products have won the first prize of China's satellite navigation and positioning science and technology progress award for many times, and the company's innovative application in the field of shared bicycles has also won the gold award of China's satellite navigation and positioning innovative application.

Fang Ting, deputy general manager of Mengxin Technology, shared that the early GNSS high-precision positioning solutions were all based on FPGA boards, mainly due to the high demand for hardware resources for high-precision positioning algorithms. Based on its unique advantages in low-power chip architecture and the team's deep accumulation in the field of RTK high-precision technology, Moncore Technology provides a strong technical support for the integration and innovation of low-power chips and high-precision algorithms.
Taking the module products developed by the company's core chips as an example, compared with the traditional board solution, there is a qualitative leap in terms of volume, power consumption and price. The emerging technology has spawned an emerging market, and between the traditional surveying, mapping, monitoring and other fields and the consumer market, Mengxin Technology has opened up an emerging high-precision application market. The traditional high-precision market, which was previously at the level of 100,000 per year, has been upgraded to the level of one million. In the future, with the continuous outbreak of demand for the Internet of Things, this will be a large-scale market of tens of millions and billions of levels.
At present, the products of Mengxin Technology have been widely used in many fields such as shared travel, automatic driving of agricultural machinery, deformation monitoring, industrial robots, intelligent transportation, construction machinery, surveying and mapping. It is believed that with the continuous iterative progress of technology and the improvement of positioning stability, in the near future, all things will have a unified accurate spatio-temporal attribute, and the intelligent society will eventually come.
Centimeter-level high-precision combination navigation module
Ensure intelligent driving high-precision continuous positioning
Back to the automotive market, with the rapid development of urbanization, our smart cars are not only facing the upgrading of centimeter-level high-precision positioning needs, but also taking into account more complex driving environments. For example, in the urban canyon, under the viaduct, half of the sky occlusion, urban patio, urban tunnel and other weak signal or short-term signalless environment, because the navigation and positioning system can not accept the satellite signal of low elevation angle, the quality of the carrier phase, pseudo-distance and other observation measurements will decline, the continuity will become worse, directly affecting the vehicle positioning performance, reducing the reliability of the system, which puts forward higher requirements for the continuous high-precision position service demand of intelligent driving.
In view of the above-mentioned urban complex environment, Monxin Technology has launched a centimeter-level high-precision combined navigation module, which provides a reliable guarantee for the high-precision continuous positioning of intelligent driving.
This module has many advantages:
The product supports multi-system and multi-frequency points to fully ensure the completeness of satellite signals
Dual-frequency RTK high-precision algorithm, dynamic positioning accuracy reaches the centimeter level
Built-in combined navigation algorithm to meet the needs of high-precision continuous positioning in various signal occlusion environments
The product is small in size, 17× 22mm in a small package size, so that the module has a small body with great energy
From the measured data in the underground garage and tunnel environment on the right, it can be seen that the product not only ensures continuous high-precision positioning in the environment without satellite signals, but also has a smooth positioning trajectory without jump points.
At present, this product of Mengxin Technology has been verified in the field of ADAS and automatic driving, and has begun to be shipped in large quantities on a large scale, providing technical solutions from Wuhan Mengxin for the technological innovation and development of smart cars.
With the wide application of accurate spatio-temporal information in the field of intelligent vehicles, the integration of GNSS positioning technology and other technologies ensures that even in harsh environments, non-line-of-sight scenarios and weak satellite signal coverage of other on-board sensors, it can still provide accurate, stable and reliable positioning information for intelligent vehicles, helping vehicles to determine the current location, so as to make an overall understanding of the current environment and facilitate the vehicle to make the next decision. With the rapid development of GNSS fusion positioning technology, the positioning accuracy and its high reliability have been further improved, ensuring that smart cars can achieve centimeter-level positioning accuracy anytime and anywhere. In addition, chip-level multi-technology integration solutions will also become a common means of intelligent management of automobiles.
Fang Ting, deputy general manager of Mengxin Technology, said that Mengxin Technology will always be committed to providing accurate and reliable high-precision location services for the smart society, and also welcomes industry experts to guide and exchange, jointly promote Beidou high-precision technology to empower all walks of life and promote the development of smart society.
