伪距差分定位

伪距差分定位

$$\begin{array}{rl}测站r：P_r^s& =({\rho }_r^s+I_r^s+T_r)+c(d{t}_r-d{t}^s)+{\epsilon }_P\\ 测站b：P_b^s& =({\rho }_b^s+I_b^s+T_b)+c(d{t}_b-d{t}^s)+{\epsilon }_P\end{array}\text{\hspace{1em}(1)}$$
星间单差消除卫星钟差，对流层和电离层延迟可得：
$$\begin{array}{rl}{P}_{rb}^s& ={\rho }_{rb}^s+cd{t}_{rb}+\sqrt{2}{\epsilon }_P\end{array}\text{\hspace{1em}(2)}$$
