On May 17, the 56th satellite of Beidou satellite navigation system was successfully launched. What kind of services can the 56 Beidou satellites in the sky provide for our daily life? Recently, CCTV News contacted Chance Location to find Beidou.
Bicycle Sharing Fitted with High-Precision Positioning Chips
If you travel often use the shared bicycle, you will find that the original parking of the chaotic bicycle, has now become orderly.
In the past, due to the shared bicycle operation managers can not grasp the real-time accurate location of the vehicle, standardized management can not begin. "Nowadays, the shared bicycles have basically been equipped with our Beidou Space-Time Intelligence's high-precision positioning chip, and we make the positioning chip very small and put it inside the shared bicycle lock." Feng Weiguo, industry business director of Beidou Space-Time Intelligence at Thousand Position, said.
Chance Location Space-Time Intelligence chip Chance Buguang BG1101 adopts domestic CPU processor, adopts dual-frequency RF baseband integration design, built-in RTK high-precision positioning algorithms and DR combination navigation algorithms, power consumption is greatly reduced to hundred milliwatts, and it adopts high sensitivity design to stably output centimeter-level positioning results.
After implanting the chip, the shared bicycle then integrates the centimeter-level positioning capability of Thousandsearch ZhiZhou FindCM, which, in collaboration with the cloud of spatial and temporal intelligent services, can improve the real-time positioning accuracy of the vehicle from 10 meters to within 1 meter. By real-time matching the precise positioning of the bicycle with the location data of highly accurate parking frames provided by the competent authorities, it is possible to grasp whether the vehicle is parked in the designated location in time, thus realizing the optimized management of picking up and returning the vehicle at the designated location and standardized parking, and enhancing the user's experience of using the vehicle.
At present, Qianxun location has assisted the accumulated millions of shared bicycles under Hello and Meituan to realize the sub-meter positioning of the whole scene, and the high concurrent request processing capability of space-time intelligent service of millions of data per second provides technical guarantee for the urban scale operation of shared bicycles.
Road inspection with Beidou high-precision positioning
The total mileage of China's highways is as high as 5.28 million kilometers, and the maintenance task is very arduous. The daily inspection work is usually done by one driver and one inspector partner, and the inspection is more than ten kilometers in one hour at most, which is inefficient and leads to the disease can not be found and repaired in time.
To address this industry pain point, Chance Location makes road inspection realize fully automated collection, and its self-developed road inspection system "Chance Chikan" integrates cameras with BeiDou high-precision positioning capability, high-performance edge computing platform, AI recognition algorithms, and digital twin capability, which can give all kinds of collection elements high-precision location and time labels, and thus accurately identify road surface diseases and so on. Highway surface diseases and other precise identification and location calculation, the recognition accuracy rate reaches 90%.
"In high-speed movement, the inspection vehicle obtains its own positioning through the Beidou system, and then accurately determines the location and type of road damage points through the vision algorithm and location algorithm on the vehicle, and the inspection efficiency is 40 times that of traditional manual inspection." He Zheqing, road inspection solution engineer of Chance Location, introduced.
High precision is a major feature that distinguishes China's Beidou from other global satellite navigation systems, bringing more diversified applications and services. In addition to shared travel and road inspection, Chance Position applies BeiDou high-precision positioning services to every aspect of life, from the operation of an airplane, intelligent driving of ground vehicles, lane-level navigation of cell phones, to road construction, bridge construction, and prevention and treatment of geologic hazards, etc. BeiDou's presence is present.
Behind this, thanks to the more than 3,700 BeiDou ground-based augmentation stations constructed and operated by Chance Position globally, they collaborate with BeiDou satellites in heaven and earth to meet the demand for BeiDou's high-precision positioning in many fields, such as land surveying and mapping and autonomous driving.
Chen Jinpei, CEO of Chance Position, introduced that the BeiDou ground-based augmentation system constructed and operated by Chance Position receives signals from BeiDou satellites in the sky in real time, and it can more accurately deduce the precise data of the satellites in the sky through the reception of these signals, so that the positioning accuracy can be improved from 3-5 meters to centimeter level.
