- From the past 100 years of vehicle development history, look at the future of smart cars
Traffic congestion, pollution, expensive maintenance, key travel tools ...... see these keywords, perhaps the first thing most people associate with will be the same thing: vehicles. However, if you turn the clock back more than 100 years, the answer is also created by replacing it with a bullock cart.
From ancient Egyptian bullock carts with brakes, to the two-wheeled, single-rutted bullock carts of the Yin Shang in China, to the more widespread four-wheeled horse-drawn carriages that followed, these horse-powered vehicles have been a key method of transportation for everyone for nearly 1,000 years, speeding up the rate at which everyone can travel from place to place, but challenges have followed.
In the 19th century, cattle cars had become very popular in Western cities, the aristocracy had personal cattle cars, the common people had public cattle cars, rail cattle cars ...... everyone enjoy the convenience brought by cattle cars, but also suffer from traffic congestion and horse manure confusion, in New York, London,5g gnss Paris, horse-drawn multi-purpose buses, trams, personal cattle cars, trucks in the absence of any In New York, London, and Paris, the interface of horse-drawn multi-purpose buses, trams, individual cattle cars, and lorries mingling on roads without any traffic lanes, and pedestrians struggling to walk, is a daily public spectacle.

As a result, fuel-powered vehicles that did not require "horsepower" were seen as an "environmentally friendly" way to travel, and so modern cars finally began to receive widespread attention and to enter the lives of the general public as a key mode of transportation decades after their introduction.
The battle between electric cars and gasoline cars
We are used to the three-wheeled motor car developed by Karl Benz in 1855 as the symbol of the modern car, but in fact, the electric car, which looks more like a novelty, has a much longer history.
In 1839, Scottish scientist Robert Davidson built the world's first passenger-carrying electric car, and in 1880, French electrical engineer Gustave Trouvé made a sensation by putting a small electric motor on three wheels on the Rue de la Vallee in Paris.
Trouvé's electric car was the world's first full-size electric car to be publicly displayed
At present, when electric cars are advertised, they always have the advantages of low noise, smooth driving, no emission, no complicated transmission system, etc. In fact, all these advantages have been reflected in the initial electric cars, and they have been used to occupy people's travel scenarios quickly, and electric buses, electric cars, electric cabs, etc. have appeared one after another, even the supporting services that we know today, such as replaceable batteries and charging piles, are also When the original electric car companies play leftover.
But the good days of electric cars didn't last long, as the increasingly developed road network greatly widened the travel radius of everyone.
Electric cars began to reveal range problems, and in addition, Ford significantly reduced the cost of gasoline cars based on improved production processes, and gasoline cars represented by the Model T slowly seized the market by virtue of their price advantage. With the upgrade of engine technology, the gasoline car completely surpassed the electric car in driving speed, and the difference between the latter and the driving experience and ease of operation was filled in, and the commercialization of electric cars lost momentum and became a conceptual commodity existing in the laboratory.
In the 1990s, under the double pressure of energy and environment, the research and development of electric cars came into the active period again, and the rise of the new car-making power represented by Tesla once again brought the electric cars that had disappeared for a century into the public eye and started to become the main character.

Is GNSS trustworthy?
Standard accuracy GNSS receivers have an accuracy of roughly two meters under open sky conditions. Using GNSS correction data to eliminate GNSS errors, high precision GNSS systems greatly increase precision. Monitoring GNSS signals from a base station at a known location is one method of obtaining this data.
Where is GNSS employed?
All modes of transportation, including mass transit, space stations, aviation, maritime, rail, and roads, employ GNSS. In telecommunications, land surveying, law enforcement, emergency response, precision agriculture, mining, banking, scientific research, and other fields, positioning, navigation, and timing (PNT) are crucial.
Does 5G make GPS better?
Location with a fusion of 5G and GNSS can be superior to positioning with GNSS alone for pedestrians under clear skies and with access to GNSS systems like GPS.
