The China Academy of Information and Communications Technology (CAICT) announced on October 14 its high-precision positioning service platform, which, based on its ability to support BeiDou's fast positioning service, is capable of achieving high-precision positioning targets.
According to Science and Technology Daily, the BeiDou High Accuracy Positioning Service Platform 2.0 improves mobile phone positioning accuracy to 1.2 meters for civilian applications.
Based on the BeiDou 2 and BeiDou 3 global satellite navigation systems, the platform is able to achieve second-level positioning and improve positioning accuracy to 1.2 meters, meaning that lane level positioning can be achieved.
The accuracy can reach sub-meter level when fitted with an on-board antenna.
On July 31, China's BeiDou III global satellite navigation system was fully completed, opening up high-quality services to the world and allowing ordinary users to use BeiDou's high-precision positioning through their mobile phones.
"The release of version 2.0 of BeiDou's positioning service means that lane level high-precision positioning using mobile phones has entered into formal commercial use,"CAICT researcher Liu Xu said, "Lane level positioning can be achieved by simply upgrading the firmware and software version, without the need for additional hardware."
BeiDou Positioning Version 2.0's ability to achieve high-precision positioning services is based on a more three-dimensional presentation of data.
Based on the layout of the BeiDou 3 system, the positioning platform is able to provide not only ephemeris data, but also more parameters such as high-precision orbital difference and high-precision ionospheric models, thanks to the layout and data acquisition of the BeiDou 3 global satellite navigation system.
It is worth noting that Apple's latest iPhone 12 series and the new iPhone 11/XR and iPad Pro cellular versions have added support for BeiDou navigation and positioning system services.
