1. The time for mobile positioning and car positioning is different
In addition to GPS positioning, mobile phones also have a function called a-GPS assisted positioning. Agps uses the base station network (GPRS) to obtain information about the communication and operation base station where your phone is currently located (the position of the signal base station), which can quickly determine your current location. Once you know the location, you can also know the parameters of the satellites above your head (which ones, frequency, position, elevation, etc.), The GPS on the device can purposefully search for satellites, and your search speed is greatly improved. You can locate in just a few seconds, so the GPS module with A-GPS assistance can locate much faster.
When positioning a car during both cold and warm starts, the time for searching for satellites is relatively long. It takes 24 satellites in space to find which satellites are above your head and determine your position, so the time may reach several minutes.
2. Mobile positioning requires traffic or WiFi to be enabled, but cars do not require it
Answer: We know that the working principle of in car GPS positioning is to use the GPS module to receive satellite signals, and then combine them with an electronic map in memory to display the set position on the electronic map, which is the position of your car.
3. The accuracy and sensitivity of mobile positioning are different from those of car positioning
Because in car GPS is mainly used for navigation, with strong signals and stable satellite reception, and merchants will update the electronic map content in a timely manner. Of course, you can also download and install it in a timely manner, otherwise some new roads may not be available on your device, which will cause unnecessary trouble.
Due to limited antenna space, the efficiency of mobile phones is not very high. Generally, the built-in navigation antenna of mobile phones is narrowband and the gain is very low, so it is greatly affected by the external environment. In many cases, it will cause the GPS antenna to not receive the signal, so it will need the network to locate, and some temporary mobile base stations required for large-scale activities will affect the accuracy of base station positioning, In addition, if the location of the router changes and the location in the WiFi database is not updated in a timely manner, it is likely to cause WiFi positioning errors.
4. Mobile positioning and car positioning signals are not affected by the same environment
This is because the two antennas have different structures.
We know that mobile phones are very small, so their antennas need to be made smaller, which results in significant signal loss. The internal components are tightly stacked together, and the antenna signal is also affected by interference from the phone, camera, memory, and other factors. In addition, sometimes users may block the antenna when holding the phone, resulting in poor and unstable GPS positioning signals.
