ABSTRACT

In this study, a GPS receiver module LEA-6 was deployed to measure the longitude and latitude of a static point on the ground in the open air. These measurement values are stored in 1-dimensional arrays in computer memory. Additionally, a top-grade GPS position recorder called iP90Pro with a very high-level positioning accuracy was employed to be used as a reference for LEA-6 module measurements. Various software techniques such as regression analysis, moving averaging algorithms, (MA), offsetting, and polynomial curve fitting was deployed on the measured raw longitude and latitude values of the LEA-6 module. As a result, the accuracy levels of these values are improved to the levels of the iP90Pro device. A mathematical analysis was carried out and formulas were developed for longitude and latitude values to bring the accuracy levels of a commercial average-grade GPS module to the accuracy levels of a top-grade GPS module.
