How to determine whether the car is equipped with a GPS positioner?trailer gps tracker Manufacturing

　　At present, the car GPS positioner has been widely used, especially in the car rental market. The owner is worried that his car will drive to an unknown place, so he often installs a GPS positioner on the car, and the car rental person does not want his whereabouts to be supervised every day. What about the positioner?

　　To determine the GPS locator on the car, we must first know the type of GPS locator. At present, there are two GPS locors on the market. The wireless vehicle GPS positioner is basically composed of built -in batteries and strong magnets or magic stickers. It has the advantages of convenient installation and anywhere in the body shell. The disadvantage is that the battery is limited and requires charging. Another cable car GPS positioner is to connect the locator directly to the vehicle power supply to provide permanent power supply. The disadvantage is that installation is a bit troublesome. Only a certain understanding of the vehicle circuit can be installed.

　　At present, the GPS positioner detector is mainly to detect the wireless vehicle GPS positioner. It can only send signals when encountering magnets. Its limitations are relatively large. If the thickness is relatively large, the detection effect is not obvious. If the GPS positioner is wired, the detection effect is not ideal.

　　We can use the radio to detect the GPS locator and adjust the radio to a clear channel. If the radio is close to the GPS positioner, there will be some harsh sounds. When the GPS positioner works, it has instructions. It is not always working and issuing signals, but manually set working hours. Generally, the positioning information is sent every tens of seconds or a few minutes. The frequency is 900MHz-1800MHz, the signal frequency of the mobile phone.
