Is GPS really powerful?

　　With the advancement of technology and the development of society, GPS positioning demand has become a well -sprayed growth. Automobiles have gradually become the most important mobility tools for ordinary people; let alone the city, even on the streets of rural areas, it is also leaked by the water gambling, which shows that the popularity of the car is high. Followed by the demand for the anti -theft and the car location of the car, most people use the car GPS positioner. Children, elderly people, car rental companies, etc. also use different types of locations. Not everyone is a professional background, and many people's knowledge about GPS positioner is one -sided. So let's talk about the topic of GPS positioning,

　　1. The maximum accuracy of the civil GPS positioner is less than ten meters. The global positioning system we use is a civil -level GPS. For GPS and Beidou, if the signal is good, the positioning accuracy is generally about 10 meters. Then if it is a base station positioning, the positioning accuracy is generally between 100 meters and 1000 meters.

　　GPS positioning accuracy can be achieved through some algorithm. However, the environmental requirements at that time were very high. If there were high -rise buildings nearby, interference signal sources and weather effects, the positioning accuracy error would definitely be relatively large. The high precision mentioned in the market can only be achieved under ideal conditions. Even if the same machine, the same place, the positioning accuracy of different time periods is different.

　　2. Not all batteries can be used as a long -term spare GPS positioner.

　　For the ultra -long standby GPS positioner, the battery capacity and characteristics determine the length of its standby time.

　　As we all know, the standby time is proportional to the battery capacity. The larger the capacity, the longer the battery life. Therefore, the battery capacity can be roughly used as a method of judgment.

　　Then, not all large -capacity batteries are suitable for such positioning. There are many types of batteries. We will also have natural discharge during use, that is, the battery consumes its own power. If the self -discharge of the battery itself is high, a large -capacity battery is a long standby in this case, but it is actually a pseudo -concept.

　　The polymer battery battery is a very obvious battery that cannot be used for long standby. Under normal circumstances, the self -discharge rate of this battery is very high, and you can imagine your own mobile phone battery. Our technology GPS positioning terminal uses lithium -Asian batteries compared to polymer batteries. Its working voltage is high and stable, with a wide range of temperature range, good structure reliability, etc. Therefore At least these basic knowledge can also say some professional terms, and it is still possible to install it.

　　3. WIFI positioning is not necessarily the most accurate. Many people think that the triple positioning and the quadruple positioner is very powerful. Especially Wi-Fi positioning is very high-tech, and can even be positioned accurately indoors. In fact, it's just a gimmick. If you understand the principle of WiFi positioning, you may not have such great hope for wifi positioning.

　　In layman's terms, the WiFi position only uses the WiFi signal source to determine the IP address of the signal and resolve it to your position. This is the address you register to the leader when pulling the line. But now almost everyone around them has wifi, and no one knows which one of these signals will be obtained, so the accuracy of the analysis is worth considering. WiFi positioning does have an auxiliary aspect, but don't rely too much.

　　The four -way positioning of our technology intelligent locator can choose the positioning mode according to the position environment intelligent to achieve the purpose of saving and accurate positioning.

　　4. The smaller the positioner, the higher the technical content, but it is not that the smaller it is, the better. Without reduction of component configuration, the smaller the volume of the positioner, the higher the technical content. Because for R & D personnel, there are so many lines and components in a limited range, testing your comprehensive control and coordination ability. But don't be too small.

　　The most important part of the positioner is the GPS module and the GSM antenna, and the space occupies is relatively large. If they ignore their space, the impact on the signal is quite large. There are no fixed GSM antennas, and even use small wire instead. This signal is not only bad, but also extremely unstable.

　　5. It is difficult for wireless positioner to stay at any time within five years. The wireless GPS positioner depends to a large extent on the battery, especially the battery capacity. If the battery is too small, it is destined not to be too large. If the battery capacity is not enough, the positioner can be paid for five years. If you want to wait for 5 years, the battery capacity must be at least 10,000 mAh or more. The smart container positioning terminal adopts a new generation of lithium battery, and the battery capacity is 10,000 mAh. Under certain conditions, it is used for 5 years and properly.
