Gps Automotive Antenna (GPS Automotive Antenna, technological Innovation leads a New era of Smart Travel)

With the rapid development of science and technology, Global Positioning system (GPS) technology has been widely used in the automobile field, which provides great convenience for people to travel. As a key component of receiving GPS signals, the performance of GPS vehicle antenna directly affects the accuracy and stability of GPS navigation, positioning and other functions. This paper will introduce the relevant knowledge of GPS automobile antenna, and discuss its application and development trend in the field of intelligent travel.

Overview of GPS Automobile Antenna

GPS automobile antenna is a device used to receive GPS satellite signals. By receiving GPS satellite signals in the sky, the real-time acquisition of vehicle position, speed, driving direction and other information is realized. Its working principle is that the antenna is used to receive the weak signal transmitted by GPS satellite. After amplification, processing and demodulation, useful positioning information is extracted.
