1. Global positioning. The number of GPS satellites is large and evenly distributed, which ensures that at least four GPS satellites can be observed at any time anywhere on the earth, and ensures the realization of global all-weather continuous navigation and positioning services (except for thunder and lightning, which is not suitable for observation).2. High positioning accuracy. The relative positioning accuracy of GPS can reach 10-6m within 50km, 10-7m within 100-500km and 10-9m within 1000km. In the precision positioning of 300-1500m project, the plane position error is less than 1mm when observed for more than one hour.Compared with the side length measured by ME-5000 electromagnetic wave rangefinder, the maximum side length difference is 0.5mm, and the mean square error of calibration is 0.3mm.3. The observation time is short. With the continuous improvement of GPS system, the relative static positioning within 20km only takes 15-20 minutes. When the distance between...

When installing a wired GPS tracker, we sometimes find a "remote fuel cut-off" function. However, this is often followed by the text "This function is to be used in conjunction with a relay". So what is a relay? What does it do and how is it wired? This article will give you the answer. A. The role of automotive relays. Automotive relays can be divided into functional and control relays in terms of use. For example, there are flashing relays, water wiper relays, and so on. Relays that simply turn the circuit on and off and convert are all control relays. The remote oil/electricity cut-off relay described in this article is a control relay. It is the equivalent of a switch that draws the armature into the circuit by means of a magnetic field, thus driving the contacts to break the normally closed contacts. In this way, it plays the role of changing the control circuit. It is the key to controlling the circuit on and off. Vehicle Relays Appearance and Work Internally How to use the ca...

With the continuous improvement of everyone's living standards, cars have become a vital travel tool for everyone. Therefore, the GPS locator has become the most widely used machine in people's daily life. It has a wide range of applications and is suitable for different groups of people, such as the car rental industry. Many places have production locations for car gps tracker, so many people come to buy them. When you are ready to buy it, you must pay attention to the following knowledge points, otherwise you will not be able to buy your favorite product. A. Compare the quality of the GPS locator When we choose a GPS locator, we must learn to compare products. Many people who buy a new GPS tracker will say that the one I used before is better. But this is not correct, because each product is used at a different time and place, and the final result is different. It must be used for a long time to feel the difference between the two GPS locators. Choosing a trusted GPS tracker is a...
