GNSS module is an all-in-one digital receiver based on the GNSS satellite positioning and navigation system, which receives signals transmitted from satellites and calculates them to provide real-time position and time data. Devices equipped with GNSS modules can be used for many applications, such as navigation and positioning.
GNSS module can receive satellite signal data from various countries, not only limited to GPS, BDS, GALILEO, GLONASS and other single satellites, according to the different algorithms and configurations, the GNSS module can be made to meet the different needs of the satellite signal receiver. It can be used in navigation, positioning and other fields. And GNSS module with ultra-low power consumption, high precision and other characteristics, can also be widely used in unmanned, intelligent industry, unmanned operation and other application scenarios.
GNSS global satellite navigation system, although it can be accurate positioning, but its own will have a certain error, even penetrate the ionosphere and troposphere and satellite high-speed movement may cause errors, harsh natural environment, towering city buildings and so on may also affect the accuracy of the GNSS system. In order to improve the accuracy of the system, some technical factors are introduced into the system to help improve the performance of the GNSS system, and these technical means are integrated into a compact and easy to apply module, which is the GNSS module.
Currently the more commonly used technologies are: PTK technology and inertial guidance technology and dual-frequency technology.
PTK technology is mainly to solve the stability and accuracy of the system, the control center will firstly reject the roughness of the received data, and then after solving the problem, the correct information will be sent to the user after correction. The full name of inertial guidance technology is inertial navigation technology, which mainly solves the problem of easy interruption of GNSS signals. In places such as tunnels and underground garages where the signals are blocked, the GNSS star search is slow and easy to be unconnected, and the GNSS module equipped with the inertial guidance technology can deduce the high-precision navigation data for the blind spot location where the terminal is located based on the device's initial positional information as well as the basic information obtained. Dual-frequency technology, on the other hand, carries different frequency band receivers on the same GNSS module, so that it can receive different frequency bands of multiple GNSS systems at the same time, thus improving the signal reception capability.
