摘要
研究了GLAONASS三种频率载波相位组合方法,以模糊度保持整数为前提,通过分析电离层延迟和观测噪声对三频组合观测值的影响,依据线性组合的长波长标准、弱电离层延迟标准、弱观测噪声标准,得出了一些新的线性组合,这些组合可以提高定位精度与定位速度。
The third carrier will be provided by modernized GLONASS satellites frequency program. With the GLONASS carrier phase observation model as a prerequisite, three frequency carrier phase combination of GLO- NASS method was researched. The effects of ionospheric delay and observation noise on the observations combined from three frequency were analyzed. According to long wavelength standard, weak ionospheric delay standards, weak observation noise standards, some useful linear combination was put forward to improve the positioning accu- racy and speed.
