GPS antenna principle
In the GPS antenna unit design, a high-frequency and low-noise amplifier is used to reduce the thermal noise of the GPS antenna and the influence of the previous unit circuits on the performance of the receiver; when the GPS satellite is used in the GPS antenna principle to achieve navigation and positioning, the user receiver.
The main task is to extract the pseudo-random noise code and data code from the satellite signal to further calculate the position, speed, and time (PVT) of the receiver carrier and other navigation information. Therefore, GPS receivers are essential user equipment.
The GPS receiver circuit currently in practical application is generally composed of four parts: antenna unit, radio frequency unit, communication unit, and solving unit. Based on the analysis of GPS satellite signal composition, this article gives the principle and application of radio frequency front-end GP2010.
1. The composition of GPS satellite signals
GPS satellite signals are synthesized using typical code division multiple access (CDMA) modulation technology. The complete signal mainly includes three components: carrier, pseudo-random code, and data code.
The signal carrier is in the L band, and the center frequencies of the two carriers are denoted as L1 and L2 respectively. The satellite signal reference clock frequency f0 is 10.23MHz, and the center frequency of the signal carrier L1 is 154 times f0, namely:
FL1=154&TImes;f0=1575.42MHz (1)
Its wavelength λ1=19.03cm; the center frequency of the signal carrier L2 is 120 times the frequency of f0, namely:
FL2=120&TImes;f0=1227.60MHz (2)
2. The principle of GPS antenna analysis
Its wavelength λ2=24.42cm. The frequency difference between the two carriers is 347.82MHz, which is approximately 28.3% of L2. This choice of carrier frequency is convenient for measuring or eliminating the propagation delay error caused by the ionospheric effect when the navigation signal propagates from the GPS satellite to the receiver.
Pseudo-random noise codes (PRN), namely ranging codes, mainly include fine ranging codes (P codes) and coarse ranging codes (C/A codes). The code rate of the P-code is 10.23MHz, and the code rate of the C/A code is 1.023MHz.
The data code is the navigation and positioning data sent by the GPS satellite to the user receiver in binary form, also called the navigation message or D code.
It mainly includes satellite almanac, satellite clock correction, ionospheric delay correction, working status information, and C/A code conversion to capture the information of the P-code and the approximate ephemeris of all satellites; the total message consists of 1500 bits, divided into 5 subframes, each subframe transmits 10 words within 6s, each word is 30 bits, a total of 300 bits, so the data The baud rate of the code is 50bps.
