GNSS GN40V series

The GN40V series is a dual-band multi-structure GNSS module that can simultaneously receive all four global GNSS constellations: GPS, BDS, Galileo and GLONASS. The GN40V series adopts the receiver chip of 12nm technology, advanced power management and good support for low-power GNSS sensing and positioning. It is an ideal solution for power-sensitive and battery-powered systems. With high-precision positioning and low power consumption, the GN40V series is very suitable for real-time tracking and sharing economy-related services and other applications. Compared with the GNSS module that tracks only L1 signals, the GN40V series can receive and track more visible satellites in multiple bands, thus significantly reducing the multipath effect in the depths of urban canyons and improving the positioning accuracy. Through the built-in LNA and SAW filters, the module achieves better sensitivity and anti-interference ability. This module has dual-band support, can provide 1m CEP accuracy value in autonomous mode, and provide centimeter-level positioning in RTK functional variants. The extended optional DR function can ensure excellent positioning performance even in weak signal areas or when GNSS signal is unavailable.

gnss_modules003 Runbo provides a series of low-power, small-scale GNSS modules, covering standard positioning, high-precision (RTK), inertial navigation positioning and other scenarios, which can meet various industry requirements. 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.

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.
