The two most frustrating things about driving are getting lost and traffic jams. Although the computer revolution is unlikely to solve these problems, it will have a positive impact.
The sensor in your car can receive the radio signal from the orbiting satellite, accurately locate your car at any time, and give a warning of traffic jam. We already have 24 navigation satellites orbiting the earth, forming the so-called global positioning system.
They make it possible to determine your position on the earth within 100 feet. At any given time, there are several GPS satellites orbiting about 1 1 1,000 miles above our heads.
According to the laws of quantum theory, each satellite contains four "atomic clocks", which vibrate at precise frequencies.
The two biggest headaches in driving are getting lost and traffic jams. Although the computer revolution can't completely solve these two problems, it will bring positive effects.
The sensor in your car is tuned to the radio signal of the orbiting satellite, which can accurately determine the position of your car at any time and inform the traffic jam. We have 24 navigation satellites orbiting the earth, forming what people call the global positioning system. Through these satellites, it is possible for us to determine your position on the earth with an error of less than 100 feet.
At any given time, there are always several GPS satellites orbiting the earth at an altitude of 1 1000 miles. Each satellite is equipped with four "atomic clocks", which vibrate at a precise frequency according to the laws of quantum theory.
When the satellite flies overhead, it will send out a radio signal, which can be received by the receiver in the car computer. The computer in the car can calculate the distance of the satellite by measuring the arrival time of the signal.
Since the speed of light is well known, any delay in receiving satellite signals can be converted into distance.
When the satellite crosses the sky, it sends out a radio signal, which can be recognized by the receiver in the computer on the car. The computer in the car will calculate how far the satellite is according to the arrival time of the signal. Because the speed of light is well known, any time delay in receiving satellite signals can be converted into distance.
