Zusammenfassung: | PROBLEM TO BE SOLVED: To achieve a kinematic processing by obtaining the three-dimensional position of an object with a measurement density being at mm order or less and drastically reducing a measurement time. SOLUTION: When the actual position of a satellite is set to a point P and the apparent position is set to a point P1 , the point P1 can be obtained within a radius range of 30 to 200 m with the point P as a center. In this manner, when the two points P and P1 are close together, the position of the point P can be obtained with the point P1 as a reference. The reference includes a microwave propagation time between the point P1 and an observation point A, the total of the refractive index of a microwave path P1A, and a critical incidence angle with assuming that a microwave radiation source exists at the measurement point P1 . A concept of check point table is introduced to accurately obtain them. |
