Now that the car has entered the era of interconnection, the demand for the Internet and GPS is increasing. Many car buyers realize that the GPS data signal of their own car has been very weak, so they want to modify a set of GPS antennas to improve the such situation. So do you know where the GPS antenna is installed?

　　The installation part of the GPS antenna can directly affect the signal level of the GPS, so it is very important to choose an accurate installation part. It is recommended to install the GPS antenna in the navigation bar under the rear cover on the upper end of the center console. If the antenna volume is relatively small, it can still have a good secret practical effect, and it is not harmful to the car interior. Although it can be installed on the A-pillar or on the windshield, the antenna is directional, and the actual effect of the transmission between the A-pillar and the windshield is significantly inferior to that under the rear cover at the upper end of the center console.

　　How much does it cost to retrofit a GPS in a car

　　This can only be distinguished by looking at the car and the well-known brand of GPS installed. Generally speaking, installing a GPS system on the market requires about 1500-3000 yuan. If you want to use a lot, the price will be higher. In fact, it is no longer necessary to install a GPS system in the car. Up to now, the upgrade rate of the in-vehicle all-in-one is relatively slow, and the traffic conditions can be seen on the mobile phone.

　　Beidou positioning system and GPS which high precision

　　At the global level at this stage, the accuracy of the GPS communication satellite navigation system is higher. If it is only for Chinese civilian use, the accuracy of the Beidou navigation satellite navigation system and the GPS communication satellite navigation system is similar. However, because there are very few road monitoring stations built in China now, the accuracy of the comprehensive specific situation or the GPS communication satellite navigation system is higher. But in the future, the level of Beidou navigation satellite navigation system in my country will definitely be greatly improved.
