摘要
用卡尔曼滤波算法综合来自单频 GPS 接收机的伪距、相位和伪距率的测量值,在数分钟内我们不仅可以得到标准偏差约5cm 的伪距估值,还可以得到同样精度的电离层延迟量,同时亦可以改正相位观测(综合多卜勒)中的初始偏差值。
When Karlman Filtering Algorithm is introduced to synthesize the
measuring value of pseudo range,phase and pseudo range rate from single
frequency GPS receiver,not only the estimate pseudo range with a stan-
dard deviation of 5cm will be obtained in several minutes,but the iono-
sphere delay of the same accuracy will be obtained as well.At the same
time,the initial deviation existing in the phase observation (integral
Doppler) will be corrected.
