1. The mobile phone positioning requires the opening of traffic or wireless, but the car is not needed. Why?
We know that the working principle of the GPS positioning of the vehicle is that the GPS module receives the satellite signal, and then combines it with the electronic map in the memory to display the set position on the electronic map, that is, the location of your vehicle.
Mobile GPS positioning principle is similar to the principle of car GPS positioning. If the GPS positioning function of the mobile phone is turned on, the GPS module in the mobile phone can be used to receive satellite signals.
But the difference is that the car GPS map is built and offline, and the merchant will update the content of the electronic map in real time, so users do not need to download and resettle themselves, so that the map can be displayed correctly without networking. The online map commonly used by mobile phones needs to be downloaded online and then displayed. If it is not connected to the network, it cannot be displayed. In fact, as long as the offline navigation data is downloaded in advance, the mobile phone can achieve the same effect.
2. The mobile phone positioning signal is greatly affected by the environment, but the vehicle positioning signal is relatively stable
This is because the structure of these two antennas is different. We know that the mobile phone is very small, so its antenna will be compared with less, causing a huge loss of signals. The internal device is closely set together, and the antenna signal will be disturbed by the mobile phone, camera, memory, etc. In addition, sometimes the user holds the mobile phone and the antenna will be blocked. Therefore, the GPS positioning signal of the mobile phone is poor and unstable.
The GPS space of the car is naturally much larger. The antenna is not a type, so the experience is better. In addition, the positioning of the car is the front car navigation, or the navigation equipment outside the roof, which has doubled the effect.
3. Why are mobile phone positioning more inaccurate and sensitive than car positioning?
Because the airborne GPS is mainly used for navigation, the signal is strong, and the satellite receiving signal is stable, the merchant will update the electronic map content in real time. Of course, you will also download and place it in real time. However, because the antenna space of the mobile phone is too small, the efficiency will not be too high. Generally speaking, mobile phones have a narrow frequency -conducting antenna band, low gain, and great influence due to external environment. In many cases, the GPS antenna cannot receive signals, so it needs to locate the network, and the temporary mobile base station required for large -scale sports will affect the accuracy of the base station positioning. In addition, if the position of the router changes and the location in the wireless database is not updated in real time, there may be problems with wireless positions.
