Abstract
As the Beidou System (BDS) and Galilei Positioning system gradually improve, people intend to make use of more satellites to offer location service for vehicle and other mobile terminal. A kind of multi-mode vehicular positioning system is proposed, the whole framework can be divided into three parts as XN647-8 positioning module, signal processing module and the antenna. XN647-8 is a high-performance, low-cost single-chip GNSS receiver module. Its signal processing module includes a high gain, low noise amplifier chip XN114 and surface acoustic wave (SAW) filter circuit. Through a oscilloscope and analyzer, BDS/GPS antenna is measured and calibrated. So multimode receiver can actually receive satellite signal strength indication close to the theoretical value. The experimental results show that the receiver have a so good performance that it can achieve real-time location tracking well.
