DATA ACQUISITION DEVICE AND METHOD FOR MEASUREMENT AND MEDIUM STORING DATA ACQUISITION PROGRAM FOR MEASUREMENT

摘要

PROBLEM TO BE SOLVED: To provide a data acquisition device for measurement facilitating setting. ;SOLUTION: For a record control part 5, conditions to be fulfilled for analyzing a base line is set. These conditions are angle of elevation, number, PDOP (position dilution of precision), etc., of a satellite for recording signal. Data acquisition devices for GPS measurement having set these conditions are placed at both ends of the baseline to be measured. The devices automatically collect data only in the time zone filling these conditions. By analyzing this record offline later, the distance of the baseline can be obtained. Without troublesome setting considering satellite conditions, necessary data can be easily collected.;COPYRIGHT: (C)1998,JPO
