In-vehicle navigation is embedded GNSS receives and demodulates satellite broadcast module C/A code signals. The receiver's longitude, latitude, altitude and time correction amount is obtained by calculating the pseudo-distance with each satellite.GPS through the serial communication port continuous output module NMEA receiver can choose the format positioning information and auxiliary information. This SKYLAB Jun Jun take you to the inventory of car navigation in the common things GNSS module use.
Car navigation
SKYLAB's GNSS module according to support the frequency band of satellite signals, is divided into single-frequency GPS positioning module, single-frequency BeiDou positioning module, single-frequency BeiDou multi-mode positioning module, dual-frequency BeiDou multi-mode positioning module; GNSS positioning module and RTK high-precision GNSS positioning module; according to the different methods of use is divided into embedded built-in type GNSS positioning module with external antenna integration GNSS G The finished products are divided into standard high-precision GNSS positioning module, RTK high-precision GNSS positioning module, weak-signal GNSS INS navigation module and inertial combination GNSS timing module according to the performance of the module.
GNSS Module
Standard high-precision positioning and navigation: From the mobile Internet to the Internet of Things, location is the indispensable basic information. When a car is traveling on the road, it needs to judge its position in real time, and the position information obtained by using the built-in standard high-precision GNSS positioning module can conveniently and accurately tell the driver the shortest or fastest path to reach the destination through the electronic map.SKYLAB standard high-precision positioning module (single-frequency GPS, single-frequency BDS, single-frequency BeiDou multi-mode, dual-frequency BeiDou multi-mode, antenna integration module, G-mouse), can be used for automobiles, cars, and other vehicles, and can be used for the navigation of the Internet of Things. mouse), can provide high sensitivity, high precision, low cost positioning and navigation solutions for the manufacture of automotive, portable handheld and other positioning terminal products, meeting the strict professional positioning requirements and personal consumption needs.
RTK high-precision positioning and navigation: with the help of 5G east wind, unmanned driving, autonomous driving and other new infrastructure technologies are being gradually improved. For smart driving cars, the lanes are narrow and the distance to roadside obstacles is short. This means that the car needs a positioning accuracy of 10 to 30 cm.The RTK built-in high-precision positioning module RTK developed and launched by SKYLAB simultaneously supports the algorithm BDS, GPS dual-satellite positioning system, and with the high-precision positioning service of the national BeiDou augmentation network, it can realize real-time cm positioning accuracy, which can satisfy the high-precision positioning needs of intelligent driving cars.
Weak signal inertial combination navigation: when the car is traveling on the road, the field of vision may be covered by the surrounding trees, trucks and urban buildings. Satellite navigation systems are susceptible to the influence of the surrounding environment, such as trees and buildings, resulting in multipath effects that reduce or even lose the accuracy of the positioning results, especially in tunnels or indoor environments.SKYLAB's weak-signal inertial combined navigation module provides real-time high-precision vehicle positioning, speed measurement, and posture measurement information GNSS When the system's signal accuracy is reduced or even the satellite signal is lost, there is no need for an odometer. information and pure inertial navigation technology, can also be long-term individual positioning, speed measurement and measurement of the car carrier, to solve the problem of vehicle positioning drift or in a weak signal environment can not receive satellite signals.
GNSS high-precision timing module: in order to achieve automation and intelligence, any application scenario involving various sub-systems working in concert requires time synchronization power, rail transportation, communications, base stations, finance, etc. The market capacity is about 10 billion yuan. Extremely low latency scenarios, such as autonomous driving and telemedicine, have higher requirements for time synchronization accuracy.SKYLAB composite GNSS timing module and high precision GNSS timing module can meet the time synchronization requirements in Telematics.
