GPS is the abbreviation of English Global Positioning System. Compared with other navigation and positioning technologies, GPS-specific positioning device technology has the following characteristics.
Continuous coverage on a global scale. Due to the large number of GPS satellites, the spatial distribution and operation cycle have been carefully designed to allow at least 4 satellites to be observed at any time on any part of the globe, thus ensuring a global scale. Continuous three-dimensional positioning throughout the day.
Realize real-time positioning. The GPS-specific positioning device can determine the three-dimensional coordinates and speed loss of the motion carrier in real time, so that the motion direction of the carrier can be monitored and corrected in real time, avoiding various adverse environments, and selecting the best route, which is difficult for many navigation and positioning technologies.

The vehicle positioning terminal is applied to a plurality of vehicle fields, and can perform real-time positioning on the vehicle, query driving trajectory, remote video, power cut control, and record whether the driver has an irregularity such as an offset route or an overload overspeed.
However, in practical applications, the vehicle positioning terminal also has its shortcomings, such as drift error, which is one of the most common problems. Although the drift error is not particularly large, it also causes a lot of trouble for the customer's management work. . Therefore, Huizhou Great-will Industrial Co., Ltd combines years of industry experience and the technology accumulated in overcoming this problem to briefly talk about the factors that affect the drift of positioning.

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...
At present, there are two main types of GPS vehicle positioning systems available on the market. One is a self-contained battery, which does not require external power supply, and the other is a self-contained backup battery. It mainly relies on the vehicle power supply.
The benefits of the self-contained battery are self-evident, that is, no wiring is required, can be placed anywhere in the car, and can be used for personal or valuable positioning. The disadvantage is that there is no continuous power supply, so the standby time is passed. It needs to be recharged for continued use, and because it needs to be recharged, it is inconvenient to be placed in a more complicated place inside the vehicle, so that each disassembly and assembly is very time-consuming and laborious.
The wiring type needs to be connected to the vehicle's power supply line, so the person who steals the vehicle can find the GPS vehicle positioning system along the power supply line and remove it. If oth...
