Along with the completion of the commercialization of 5G and the popularization of the basic construction of communication base stations, more and more 5G cell phones are appearing in the sales market, which are quickly stepping into thousands of homes due to their low latency time, high-speed transmission, intelligent systems and other advantages. The automotive industry,gnss module which is pursuing perfect information technology, is certainly not lacking. 5G cars once became a hot topic, and more and more automotive companies are gradually using 5G communication technology in their new cars.

5G car revolution coming

Recently, according to foreign media reports, General Motors and the American Telephone and Telegraph Company (AmericanTelephoneandTelegraph, commonly known as AT&T) has strategic cooperation, from 2024 gradually the group's car line will be equipped with 5G cellular mobile network. After the car is equipped with 5G some roles will be enhanced on the original premise, such as the network speed of the application software in the car, colorful information content in the car, games and entertainment and other multimedia system role, improve the ground full coverage, navigation map quality, etc.

In the future, 5G in V2X (vehicle networking platform), enhance the feeling of safe driving and driverless level will show their talents, today's motor vehicles are more intelligent, set intelligent interconnection, information content game entertainment integration, this all depends on the cellular mobile network process development trend. Unmanned driving is attributed to the exploratory use of V2X, the vehicle network platform according to wireless communication technology, global positioning site navigation, remote control magnetic induction technicality to carry out the car to the external information exchange, to complete the manual type of safe driving and driverless compatibility.

Along with the use of 5G communication, its low latency time, high-speed transmission, intelligent system advantages, may further promote the car to external information content interchange, give the car safety factor; 5G can complete the shared resources instant communication, instant grasp of highway traffic situation, intelligent travel; car information content game entertainment role to improve, enhance safe driving feeling, 5G car history time revolution has gone Come.

The dream future of car-road interconnection

Every public transportation participant individual, all a digital divide, 5G car networking platform is not only C-V2X (C means cellular mobile network), the X in V2X refers to all the road public transportation natural environment, including cars, people, public transportation facilities, etc., create network communication between each other to complete the sharing of resources to communicate.

V2X can turn the car into a second pair of "eyes" for the driver, but at this stage, V2X technology has just been developed, and the security rate that can be applied is relatively limited, so it is difficult to reach the daily complicated public transportation natural environment, and the arrival of 5G period can give a smooth and fast Internet, and give a strong backbone for driverless. Therefore C and V2X are indispensable to complete the dream of vehicle-road interconnection in the future, and 5G is there for all to see.

What does GNSS stand for?

The abbreviation GNSS, which stands for Global Navigation Satellite System, is used to refer to all satellite navigation systems that offer global coverage and autonomous geospatial placement. This phrase refers to systems such the GPS, GLONASS, Galileo, Beidou, and other local ones.

What kinds of codes are employed by GPS?

The two different GPS code types are listed below.
C/A code stands for coarse acquisition code. P code, or precise code.

What distinguishes GPS from other GPS?

Both the A-GPS and GPS navigational aids use data from satellites to pinpoint their precise locations on Earth.
...
Comparison table. An A-GPS GPS
Reliability A-GPS location determination is marginally less precise than GPS GPS devices have a 1 meter accuracy limit for determining location coordinates.

The GNSS signal measurement method

The word "GNSS" (Global Navigation Satellite System) refers to a group of satellites that transmit signals from orbit. By utilizing the timing and positioning information included in the signals originating from space, GNSS receivers pinpoint their exact location.

How is distance measured using GNSS?

The code measurement principle

Therefore, the distance between the receiver and the satellite can be computed as the product of the measured time difference and the speed of light. The position of the GNSS receiver can theoretically be found by simultaneously measuring against three satellites.
