Mobile GPS positioning and best hidden gps tracker for car are essentially the same, both through the GPS module, the use of global satellite positioning system to locate, both do not need traffic in positioning, but the signal strength is different. The difference between mobile GPS positioning and best hidden gps tracker for car See here, it is estimated that many people will have questions in their minds, since the principle is similar, why mobile GPS positioning and best hidden gps tracker for car there are so many differences? Such as these: 1, mobile phone positioning needs to open traffic or WiFi to locate, but the car does not need, which is why? A: We know that the working principle of car GPS positioning is that the GPS module receives satellite signals, and then the electronic map in the memory is combined to show the location of the setting on the electronic map, which is the location of your car. Mobile phone GPS positioning principle is similar to the car, open the GPS positioning function of the mobile phone, you can use the GPS module in the mobile phone to receive satellite signals to locate. The difference is that the car GPS map is built offline, the business will update the content of the electronic map in time, the owner does not need to download and install themselves, so the Internet does not need to be able to correctly display the map. The online map generally used by mobile phones needs to be downloaded online and then displayed, if it is not connected to the Internet, it cannot be displayed. In fact, as long as the mobile phone downloads the offline navigation data in advance, it can achieve the same effect. In addition, some people use mobile phone positioning, in fact, the use is not GPS positioning function, but WiFi positioning or base station positioning, that is, your mobile phone and the mobile tower or WiFi hotspot to obtain data exchange to locate, this is definitely the need for networking. 2, the mobile phone positioning signal is greatly affected by the environment, the car positioning signal is more stable? This is because the antennas are constructed differently. We know that the mobile phone is very small, so its antenna must be smaller, which causes a large signal loss, internal devices are tightly stacked together, the antenna signal will be interfered by the phone, camera, memory, etc., plus sometimes when the user holds the mobile phone, it will block the antenna, so the mobile GPS positioning signal is very poor and unstable. The car GPS space is naturally much larger, and the antenna is not the same type, so the experience is better, and the car positioning is the front-loaded car navigation, or the antenna is the navigator outside the roof, the effect is another step. 3. Why is mobile phone positioning less accurate and less sensitive than car positioning? Because the car GPS is mainly dedicated to navigation, the signal is strong satellite reception signal is stable, and the business will update the electronic map content in time, of course, you also download and install in time, otherwise there may be no new road repair on your device, which will cause unnecessary trouble. The mobile phone because the antenna space is too limited, resulting in its efficiency is not too high, the general mobile phone built-in navigation antenna is narrowband, gain is very low, so it is greatly affected by the external environment, in many cases will lead to GPS antenna can not receive signals, so it will need the network to locate. The temporary mobile base stations required for some large-scale activities will affect the accuracy of the base station positioning, in addition, if the location of the router has changed, and the location in the wifi database is not updated in time, it is likely to lead to wifi positioning errors. 4, mobile phone positioning is very fast, generally seconds fixed positioning, and car positioning takes a certain amount of time, a few seconds when fast, a few minutes when slow, why? This is also very well understood, because in addition to gps positioning, the mobile phone has a function called A-GPS assisted positioning, Agps uses the base station network (GPRS) to obtain the information of the communication operation base station where your mobile phone is located at this time (the location of the signal base station), you can quickly know where you are now, know the location, At this time, the satellite parameters (which several, frequency, position, elevation and other information) above your head will be known, the GPS on the device can be very purposeful to search for satellites, at this time your star search speed is greatly improved, A few seconds can be positioned, so the GPS module with A-GPS assisted positioning positioning time is much faster. When the car is positioned in the cold start and warm start, the search time is relatively long, and the 24 satellites in space need to be searched to find which satellites are above their heads to determine their position, so the time may reach a few minutes. The above is the difference between Heze Zhiren's mobile phone GPS and best hidden gps tracker for car, both of which have their own advantages in use, although they also have defects, but they can meet the needs of their own use in their own fields. Heze Zhiren is a high-tech enterprise specializing in car GPS positioning, and will contribute to the development of the best hidden gps tracker for car navigation in the future.
