In-vehicle navigation is to receive and demodulate the broadcast C/A code signals from satellites with the help of embedded GNSS module. Through the operation and each satellite pseudo-distance, using the distance rendezvous method to derive the receiver's longitude, latitude, altitude and time correction amount of the four parameters.GPS module through the serial communication port constantly output NMEA format positioning information and auxiliary information for the receiver to choose the application. I bring you together to inventory the common use of GNSS module in car navigation.
Car Navigation
JUNODA's GNSS module is divided into single-frequency GPS positioning module, single-frequency BeiDou positioning module, single-frequency BeiDou multi-mode positioning module and dual-frequency BeiDou multi-mode positioning module according to the frequency band of the supported satellite signals; it is divided into standard high-precision GNSS positioning module and RTK high-precision GNSS positioning module according to the difference in the way of use; it is divided into embedded built-in GNSS positioning module and external antenna integrated GNSS positioning module. GNSS modules are divided into embedded built-in GNSS positioning modules and external antenna integrated GNSS G-mouse products; according to the different performance of the modules, they are divided into standard high-precision GNSS positioning modules, RTK high-precision GNSS positioning modules, weak-signal GNSS + INS inertial combination navigation modules and GNSS timing modules, and so on.
GNSS Module
Standard high-precision positioning and navigation: from mobile Internet to Internet of Things, location is a basic indispensable information, the car driving on the road, you need to judge your own position in real time, and use the built-in standard high-precision GNSS positioning module to obtain the location information, with the electronic map to realize the navigation, which can conveniently and accurately tell the driver to go to the destination of the shortest or the fastest path.SKYLAB SKYLAB's standard high-precision positioning modules (single-frequency GPS, single-frequency BDS, single-frequency BeiDou multi-mode, dual-frequency BeiDou multi-mode, antenna integration module, G-mouse) can provide high-sensitivity, high-precision, low-cost positioning, navigation and other solutions for the manufacture of vehicle-mounted and portable hand-held and other positioning terminals, and can satisfy the stringent requirements of professional positioning and personal consumption needs.
RTK high-precision positioning and navigation: with the arrival of the new infrastructure boom, with the east wind of 5G + new infrastructure, driverless, autonomous driving and other technologies are gradually improving, for intelligent driving cars, the lanes are very narrow, and the distance between the obstacles on the side of the road is also shorter. This means that the car's requirement for positioning accuracy is 10 to 30 centimeters.
Weak Signal Inertial Combination Navigation: When the car is driving on the road, the vision may be blocked by the surrounding trees, peer trucks, and urban buildings, the satellite navigation system is easily affected by the surrounding environment, such as trees and buildings, resulting in a multi-path effect, which reduces or even loses the accuracy of the positioning results, especially in the tunnels or indoor environments, where the satellite navigation system is basically unavailable. JUNODA weak-signal inertial combination navigation module provides real-time high-precision vehicle positioning, speed and posture information, in the GNSS system signal accuracy is reduced or even the loss of satellite signals, without the help of odometer information, the use of pure inertial navigation technology, but also in a longer period of time alone on the car carrier for high-precision positioning, speed and posture, to solve the problem of weak-signal environment, the vehicle positioning drift or can not receive satellite signals. GNSS Timing Module
GNSS timing module high-precision timing: in order to realize automation and intelligence, any application scenario involving the collaborative work of various sub-systems requires time synchronization, and the market capacity of electric power, rail transportation, communications, base stations, and finance, etc. is about 10 billion. Extremely low-latency scenarios such as automatic driving and remote medical care require even higher time synchronization accuracy.
