GPS第三频载波及民用码的信号质量分析
QUALITY ANALYSIS OF GPS L5 SIGNAL
【摘要】 介绍了L5载波的特点,分析了L5载波对GPS测量的影响,用实测数据分析了三频载波的信噪比及各个民用码的噪声水平。
【Abstract】 We describe the characteristics and impacts of L5 signal.A detailed analysis of the signal-to-noise ratio(SNR) on three frequencies and the noise level of three civilian codes are presented.The SNR of L2 signal is a little higher than that of L5 signal.The standard deviations of multipath and noise values of C/A,L2C and C5-codes are at the same level.
