GPS positioning system has become more and more a helper for fleet management. Its powerful functions bring great convenience to managers, save time and effort, and at the same time save costs to a certain extent, improve business level and efficiency, mainly Effective management of the fleet is achieved through the following functions:
Vehicle positioning function: After selecting the vehicle that the enterprise needs to view, the GPS positioning system automatically maximizes the vehicle position on the map. The vehicle icon flashes rapidly to indicate that the vehicle is running, and the vehicle icon flashes slowly to indicate that the vehicle is stopped.
Real-time tracking function: When the enterprise needs to track a certain vehicle in real time, the GPS positioning system automatically maximizes the current location of the vehicle and the driving trajectory of the first two minutes. The map continuously describes the vehicle to be monitored with blue lines. R...
First of all, it is necessary to understand the working principle of GPS speed measurement and speedometer: After receiving the radio waves of more than 4 satellites and above, the GPS terminal can determine the position of the vehicle and calculate the driving time through the change of position in a very short time. The distance is obtained to obtain the driving speed; the signal of the speedometer comes from the speed sensor on the gearbox or the output shaft, which is synchronized with the rotational speed of the wheel. After the signal is processed, it is sent to the stepping motor pointed by the control pointer in the speedometer to display the current speed to the user.
According to the principle of the speedometer, there are two main reasons for the difference between the speedometer and the actual speed:
The tire pressure of the automobile tire is insufficient or due to wear during use.Its radius gradually decreases. The speedometer's signal is synchronized w...
There are many manufacturers of GPS positioning devices, but not all of them are "a man with professional training". Therefore, we must know how to distinguish between true and false when purchasing GPS positioning device. There are several common senses to know.
1. Civil GPS positioning device with a maximum accuracy of less than 10 meters
The GPS positioning devices we are using now belong to the civilian-grade GPS. (We don't discuss it at the military level for the time being). In the case of good signal (under ideal conditions such as open ground and sunny weather), the positioning accuracy is generally around 10 meters. If it is LBS (base station) positioning, the positioning accuracy is generally between 100 meters and 1000 meters.
GPS positioning accuracy is achieved by a certain algorithm. For the environment at that time, if there are high-rise buildings, interference signal sources, and cloudy weather, the positioning accuracy error will definitely be relatively large. The...
Today's increasingly developed, whether enterprises or individuals want to control the car at any time, many people are uncertain when buying a car GPS location tracker, because it is not sure which type of wired car GPS tracker and wireless GPS tracker is good? In fact, "every coin has two sides", the focus of choosing a GPS tracker is whether it is suitable, how to avoid weaknesses. I am here to give you a detailed introduction to the advantages and disadvantages of the wired car GPS tracker, as follows:
wired car GPS tracker
The "line" of the wired car GPS tracker is used to connect the vehicle's power line, ACC line, etc. The wired car GPS tracker working power is provided by the vehicle. Generally, the built-in miniature battery can make the device work from 0.5 hours to 1.5 hours after the power is cut off. It can prevent the device line from being maliciously cut off and unable to continue working.
Because the working power of the wired GPS t...

For part of the best car tracking device, as long as the locator is well maintained, properly installed, the use is more regular, want to use to 5-6 years really no problem. When I first bought car location tracker, I believe many friends have asked the same question. That is: how long will the locator last? Or how often does the best car tracking device have to be replaced?
Probably the most common thing consumers hear is that the average locator will last 5-6 years. So, a constantly updated electronic products, it really can be used for 5-6 years so long?
Some of the more elegant businesses may be from the potentiate power protection and so on, the use of better and more durable chip, so the best car tracking device naturally life is longer.
But the ordinary car location tracker, not to mention can do waterproof and dustproof and high temperature, if the use of ordinary chip, material is also very common material, even if consumers carefully protect good attempt to use three, fiv...
GPS tracking device tracker constituent elements
GPS tracking device trackeris also known as the car positioning tracker, mainly anti-theft GPS positioning products. The functions of the car location tracker generally include SMS location, timing location, network query, remote monitoring and remote locking, etc.
The world's smallest gps tracking device tracker, volume only matchbox size, avoid the car down the line, just pick up the car battery plus or minus two wires, can locate, reserved for real-time vehicle tracking vehicles in the three months to the route, the vehicle automatic real-time positioning, it can locate interval timing track record car conform, no need professional technicians to install, fool. If the target gps tracking device tracker is stolen, stolen, robbed and other emergencies, you can use a mobile phone or computer, query the location of the vehicle, and real-time tracking location of the vehicle moving route, so that you can easily find your car.
