GNSS GN80U series

The GN80U provides dead reckoning through an integrated Inertial Measurement Unit (IMU) to provide continuous, high-precision positioning. It integrates state-of-the-art algorithms that incorporate IMU data, GNSS measurements, wheel pressure sensor input, and vehicle dynamics to provide accurate lane positioning where GNSS alone is not possible. The module supports standard RTCM corrections from third-party base stations or calibration networks, enabling centimeter-level positioning in seconds, making it excellent in challenging conditions such as urban canyons. The GN80U is a dual-band GNSS module that complies with the AEC-Q100 standard and integrates multi-band RTK technology to achieve centimeter-level accuracy. The module uses the stmicroelectronics ® fifth generation positioning receiver platform with 80 tracking channels and 4 fast acquisition channels, compatible with up to 4 constellations (GPS, GLONASS, Galileo and BDS) as well as QZSS. The GN80U design electronic bom is minimal and easy to integrate, making it ideal for mass market adoption. Due to its compact design, light weight and low power consumption, it is ideal for vehicle markets such as automotive navigation, ADAS and V2X, as well as precision intelligent agricultural applications.

The standard positioning module is only for common precision needs, which is generally single frequency band, without RTK algorithm prebuilt; While high-precision and inertial navigation positioning can be used to have higher requirements for positioning accuracy and scene. High-precision positioning requires the collarboration of differential reference stations, which can generally reach sub-meter or even centimeter accuracy. The positioning principle is that the terminal receives the navigation satellite as a receiver to obtain the basic positioning, and sends the positioning data to the differential reference station. The differential reference station returns the corrected original positioning data according to this positioning data. After receiving the corrected data, the terminal will calculate the corrected positioning coordinates through differential decomposition. According to the positioning accuracy, it can be listed with "single point solution", "differential solution", "floating point solution" and "fixed solution", and the positioning accuracy is gradually improved. gnss_modules001

Taking the railway construction scene as an example, railway construction often faces complex and changeable terrain and geology, and the traditional surveying methods are difficult to meet the construction requirements in terms of efficiency and accuracy. The support of GNSS surveying and mapping technology has greatly shortened the time required for surveying and mapping in railway construction, effectively improved the working efficiency, and improved the quality of railway engineering surveying. Another scenario in railway is maintenance. The maintenance personnel with high-precision terminal need to be able to accurately locate on which rail to avoid affecting the operation of trains on the near rail or unnecessary safety hazards. When the personnel close to the running train rail, they will give a real-time warning of danger. Once the personnel walk on the rail for maintenance, the position can be displayed on the high-precision map in real time for the convenience of the back-end personnel to view.
