长波长、弱电离层延迟、低噪声的线性组合观测值能够实现整周模糊度的快速确定,而组合的波长、电离层延迟系数及观测噪声都由组合系数决定。在用频率因子、电离层延迟因子和观测噪声因子表征组合波长、电离层延迟系数及观测噪声大小的基础上,利用搜索法得到了适合于整周模糊度解算的BDS/GPS B1、B2、L1、L2四频组合观测值系数,利用函数法得到了观测噪声最优时组合观测值系数和与频率因子及电离层延迟因子的函数关系,结果表明,(0,-1,0,1)、(-1,0,1,0)和(-1,-1,1,1)3组系数确定的组合观测值具有较长的组合波长,较小的电离层延迟误差和观测噪声,有利于整周模糊度的解算。

Long wavelength,weak ionospheric delay and low noise linear combination observational value can realize a quick determination of the integral ambiguity,and all the combined wavelength,the iono-spheric delay coefficient and observational noise are determined by the combination coefficients.On the ba-sis of the frequency factor,the ionospheric delay factor and the observational noise factor characterized by the combined wavelength,the ionospheric delay coefficient and the observational noise,the BDS/GPS B1、B2、L1、L2 four-frequency combination observation coefficients suitable for integral ambiguity resolution are obtained.The functional relationships of the combination observation coefficients,the frequency factor and the ionospheric delay factor are obtained under the condition that the observation noise is in the lowest by utilizing the function method.The results show that the combination observational values determined by the three groups,i.e.,and are comparatively long in the combination wavelength,comparatively weak in the ionospheric delay error and comparatively low in the observation noise,which are suitable for inte-gral ambiguity resolution.
