With the rapid development of intelligent transportation, autonomous driving, smart city and other fields, high-precision positioning technology is becoming an indispensable key support. As a leading enterprise in China's satellite navigation industry, BDStar has continuously innovated in this field and launched the UM981 series of full-system full-frequency high-precision RTK/INS combined positioning modules. This new product not only represents BDStar's technological progress, but also shows the prospect of wide application in multiple industries.
Technological innovation: the perfect combination of satellite navigation and inertial navigation
The biggest highlight of the UM981 series module is that it integrates satellite navigation and inertial navigation technology, and can simultaneously receive and process signals from various global satellite navigation systems such as BDS, GPS, GLONASS, Galileo, etc. This full-system full-frequency coverage greatly improves positioning accuracy, especially in complex environments such as dense urban high-rise buildings, which can ensure signal stability and accuracy. By fusing inertial navigation data, the module can continue to provide high-precision positioning services in scenarios with limited signals, especially in tunnels, forests and other places with serious occlusion.
High-precision positioning: accurate positioning within 10cm, convergence in 10 minutes
One of the most striking features of the UM981 series is its ability to achieve positioning with an accuracy of 10 cm in less than 10 minutes. Thanks to PPP (Precision Single Point Positioning) technology and high-frequency processing capabilities, the module can quickly complete the fusion and calculation of satellite and inertial navigation data, ensuring that high-precision data is provided in a real-time dynamic environment. This is especially important for scenarios that require precise control and operation, such as autonomous driving and precision agriculture. The module supports 50Hz frequency single point positioning + RTK positioning data output, as well as 100Hz integrated navigation data output, ensuring that the data is still accurate and reliable even in high-speed movement or complex terrain.
Wide range of applications: from autonomous driving to full support for smart cities
The UM981 series modules can not only provide services for traditional surveying and mapping, precision agriculture and other industries, but also show strong applicability in emerging fields such as autonomous driving, intelligent transportation, and unmanned aerial vehicles. Especially in autonomous driving, the RTK function of the module can greatly improve the real-time positioning accuracy of the vehicle and ensure the safe driving of the vehicle in complex urban environments. The UM981S module even supports tilt measurement to achieve accurate sampling and lofting without the need for complex equipment calibration, which simplifies the complex operation of traditional RTK systems and brings great convenience to the surveying and mapping industry.
For example, in practical applications, BDStar UM981 series modules have been used in an autonomous driving project. The project required vehicles to drive in the downtown area with many high-rise buildings, and the traditional GPS system could not provide sufficient accuracy due to signal reflection and occlusion problems. The UM981 module ensures that the vehicle can still achieve 10cm accurate positioning in this environment through its powerful multi-frequency receiving capability and inertial navigation technology, which greatly improves the navigation safety of the vehicle.
Market prospects: the rapid development of the Beidou navigation industry
With the completion of the Beidou-3 system, China's satellite navigation industry has entered a golden period of rapid development. According to the data released by the China Satellite Navigation and Positioning Association, in 2023, the output value of core industries related to Beidou navigation has reached 128.9 billion yuan, showing a steady upward trend compared with previous years. As an important participant in this industry, BDStar has launched the UM981 series module, which will further promote the expansion of the Beidou navigation industry in the global market. Especially in the context of China's vigorous development of new energy vehicles and intelligent transportation infrastructure, the UM981 module will undoubtedly play an important role.
Competitiveness and challenges: the key factors for the implementation of marketization
Although the UM981 series modules have significant technical advantages, there are some real-world challenges that need to be addressed for their widespread use in the market. The first is the issue of price. The cost of high-precision positioning modules is relatively high, especially in large-scale applications, how to balance technical performance and cost control is a problem that enterprises must solve. The second is the coordinated development of the industrial chain, and the promotion of the UM981 series needs to be jointly promoted with partners in intelligent transportation systems, autonomous driving and other industries in order to realize the commercialization of the technology.
Taking autonomous driving as an example, the application of BDStar UM981 module not only depends on the technical performance of the module itself, but also requires in-depth cooperation with automobile manufacturers, intelligent transportation platforms and other parties to ensure the seamless connection and optimization of the module and the vehicle system. This cross-industry collaboration will be one of the key factors for the success of the UM981 family of modules in the future market.
Conclusion: Driving a new future of intelligent transportation
BDStar UM981 series full-system full-frequency high-precision RTK/INS combined positioning module not only demonstrates the innovation ability of Chinese enterprises in the field of global high-precision positioning technology, but also provides strong technical support for the digital transformation of multiple industries. With the vigorous development of emerging industries such as intelligent transportation and autonomous driving, the UM981 series modules will become an important cornerstone in these fields. Its precise positioning, reliable performance and wide range of application scenarios will promote the Beidou navigation industry to a new peak in the future.
As a new generation of BDStar, UM981 series modules will undoubtedly bring more opportunities and challenges to the intelligent transportation industry in China and the world.
