Gps differential Antenna (GPS differential Antenna, the core component of positioning technology)

With the rapid development of Global Positioning system (GPS) technology, it is more and more widely used in various fields. As an important part of GPS technology, the performance of GPS differential antenna plays an important role in positioning accuracy. This paper will introduce the concept, working principle, application scene and future development trend of GPS differential antenna in detail.

Overview of GPS differential Antenna

GPS differential antenna is a kind of special equipment for receiving GPS satellite signal. It calculates the longitude, latitude, height and other information of the receiver by receiving the signal sent by GPS satellite. GPS differential antenna is composed of antenna part and receiving part, in which the antenna part is responsible for receiving satellite signal, and the receiving part is responsible for processing the signal and solving the position information.

Working principle of GPS differential Antenna

The working principle of GPS differential antenna is mainly based on the characteristics of GPS satellite signals. GPS satellite sends out radio signals, which arrive at the ground receiver after propagation delay. The GPS differential antenna calculates the position of the receiver by measuring the propagation time of these signals and combining with the known position of the satellite. In order to improve the positioning accuracy, GPS differential antenna uses differential technology to compare satellite signals at different positions. The common error is eliminated so as to improve the positioning accuracy.
