Title:
OBSERVATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/195649
Kind Code:
A1
Abstract:
The objective of the invention of the present application is to resolve the problems faced by the prior art, in other words to provide an observation system capable of reducing calculation time and calculation cost by directly processing measured data without performing filtering or smoothing processes. The observation system of the invention according to the present application is a system for obtaining the displacement of an observed point by satellite positioning, and is provided with a positioning means (110), a positioning data storage means (121), a positioning data reading means (128), a reference value computing means (129), a displacement vector computing means (126), and a movement determining means (127). Of these, the reference value computing means (129) computes reference values for each observed point on the basis of a plurality of items of historical positioning data measured at the same positioning time, and the displacement vector computing means (128) computes an observed point displacement vector on the basis of the positioning data and a reference value corresponding to the positioning data.
