GPS positioning, GPS navigation, these GPS applications gradually make GPS technology known, and now many smart phones have a new trick to attract everyone's attention, mobile GPS came into being. Mobile phone GPS, as its name implies, is a GPS function implemented on a mobile phone. One is GPS navigation and one is GPS positioning and tracking. Mobile phone GPS and mobile phone positioning are no strangers to many friends who use smart phones. The following is a small series to share some knowledge about mobile phone GPS and mobile phone positioning system for everyone to better understand mobile phone GPS and mobile phone positioning system.

First of all, let's talk about mobile phone GPS, which is the GPS positioning and navigation function implemented on the mobile phone platform. With the development of technology, there will be more applications. This is easy to understand, that is, the mobile phone has a general mobile phone communication function such as texting, making a call, taking pictures, MP3 and other basic functions, and can also use the mobile phone to achieve GPS positioning and navigation. The current GPS mobile phone is also a mobile phone with navigation function, so the GPS mobile phone can also be called a GPS navigation mobile phone or a mobile phone with GPS navigation function.
Advances in science and technology have made people's demands for life higher and higher, and the quality of life has become higher and higher, assuming such a situation. A few friends have gathered at a certain location, but this location is not very familiar, and the terrain is relatively complicated. If you ask for directions, you may have to wait until halfway to reach the end. At this time, if your mobile phone is GPS. Mobile phone, all problems are solved, the advantages of mobile GPS reflect, open the GPS application of the mobile phone, enter the end point you want to go, use GPS search query, you can quickly find the best route, do not worry about the agreed place Asking for directions back and forth, but I don't know where it is. Let's assume a situation. If you and your friends accidentally get lost while going out to play, it is not easy to find someone. The function of GPS positioning tracking of mobile phones can be applied.
Multiple factors affect the popularity of mobile phone GPS
By integrating GPS in the mobile phone, it is very easy to realize the autonomous navigation of the vehicle, and the user will no longer be lost and lost his trip, which is convenient and practical. More and more GPS-enabled mobile phones will in turn drive the development of location services (LBS). Another factor that has led to the integration of GPS functionality in mobile phones is policy orientation, and national policies strongly support the development of mobile GPS.
The higher the receiving sensitivity of the GPS chip, the faster the search star speed, the lower the power consumption, the more convenient the use, and the wider the user's use. However, the GPS signal is very weak, and any interference will affect its reception and product performance. Therefore, the degree of design optimization of GPS products will have a great impact on the performance of the products, thus affecting the user's recognition and acceptance of GPS products. The cost of the GPS system includes the price of GPS modules, GPS processors and other related components and maps, resulting in a relatively high cost and price of the GPS system. Many users are still unable to bear this price. However, with the reduction of cost and advancement of technology, many terminal manufacturers and mobile phone design companies are launching corresponding programs and products. Mobile phone GPS chips and solutions are showing a dispute between soft and hard solutions, and power consumption and receiving sensitivity have become the focus of attention.
Let's talk about the mobile phone positioning system. We can understand the mobile phone positioning system in this way. It refers to the location information (latitude and longitude coordinates) of the mobile phone or terminal user through specific positioning technology, and the marked object is marked on the electronic map. Location technology or service.
Don't think that the mobile phone positioning system must be the GPS positioning of the mobile phone. This is not accurate. First, let's talk about the positioning technology. There are two kinds of positioning technologies, one is based on GPS positioning, and the other is based on the base station of the mobile operation network. Positioning. The GPS-based positioning method uses the GPS positioning module on the mobile phone to transmit its own position signal to the positioning background to realize the positioning of the mobile phone. The base station positioning is to determine the location of the mobile phone by using the measured distance of the base station to the distance of the mobile phone. The latter does not require the mobile phone to have GPS positioning capability, but the accuracy depends largely on the distribution and coverage of the base station, and sometimes the error will exceed one kilometer. The former has a higher positioning accuracy. There is also a way to use Wifi to locate in a small area.
Mobile phone location classification
The mobile phone positioning system can be divided into two types according to the way of providing services: a self-owned mobile phone positioning system and a public positioning system. According to the different functions of the mobile phone, there can be two types of positioning, the SMS version of the mobile phone positioning and the WAP version of the mobile phone positioning. Proper use of these positioning systems can provide us with a lot of convenience in our lives or work.
By analyzing the mobile phone GPS and mobile phone positioning system, we can see the difference and connection between the two. Although the mobile phone integrated GPS has been used, it is still not popular. With the development of GPS technology and the improvement of the performance of mobile phones, mobile phone GPS And mobile phone positioning system should be one of the basic functions of our mobile phone, let us wait and see.
