I know that most GPS jammers are also in the car, but will it affect the GPS positioning of the phone?

GPS jammers are actually GPS signal jammers, which are mainly used in cars to shield GPS positioning devices on cars. After the device is turned on, the GPS positioning on the car fails. Of course, the GPS positioning on the mobile phone cannot be used normally. However, mobile phones can still be positioned by taking data traffic. Generally, GPS jammer can be used for less than one hundred dollars.
