Embodiment Construction
[0040] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0041] combine figure 1 , provide the optimal embodiment of the dynamic determination method of the integer ambiguity in the RTK positioning of the present invention, comprising the following steps:
[0042] (1) Each epoch independently solves the floating-point solution and the corresponding covariance matrix of the integer ambiguity;
[0043] (2) Carry out the whole week ambiguity search to obtain a set of ambiguities of all satellites in the i-th epoch And an indicator that characterizes the reliability of the ambiguity of the i-th epoch——Ratio i value, j is t...
