METEOROLOGICAL INFLUENCE AND A CORRECTION METHOD FOR GPS DISPLACEMENT MEASUREMENTS

Abstract

In order to improve the reliability of displacement measurements, using the Global Positioning System, it is an essential task to detect the exact displacements from measurement data scattered among various types of errors. This paper discusses the atmospheric delay caused by changes in weather conditions as an important factor in the measurement errors, and proposes an error correction method for it. A computer program is developed, and it is applied to practical measurement results in order to verify the proposed method.
