Embodiment Construction
[0046] The present invention will be further described below in conjunction with the accompanying drawings.
[0047] refer to figure 1 , the specific implementation steps of the present invention are as follows:
[0048] Step 1. Based on all GNSS horizontal velocity fields in the research area, establish an overall rotation and uniform strain model, and solve the model parameters and the corresponding least squares correction number vector V according to the least squares principle;
[0049] Wherein, the model of the overall rotation and uniform strain is:
[0050]
[0051] In the above formula, L is the observed velocity vector, including eastward and northward velocities; V e , V n Respectively represent eastward and northward speed; R earth Indicates the radius of the earth; Indicates the latitude and longitude position of the station; Indicates the geometric center of the study area; ε ee , ε en , ε nn Represents three principal strain parameters, which are e...
