Accuracy analysis of real-time kinematic positioning applications with continuously operating reference station in the urban and forested areas

The positioning process is determined by GPS+GLONASS+GALILEO and other satellite systems that help in processing and analyzing by using transmitted signals from space and which comes to mind as the positioning system at the present time. More precise and higly accuracy positioning can be achieved with the increase of satellite based systems in the space. Moreover, the positioning operations are taken place economic, fast, real time and cm-level accuracy with continuously operating reference stations and is played an important role in various fields of usage such as civil, scientific and military. In this thesis, accuracy of real time kinematic positioning applications using reference stations is analyzed in both urban and forested areas which are satellite views are not or less, multipath effect is intence. Six points has assigned in the study area. These points have been determined two points in the built-up areas, other two points in the forestland and others two points are that little far in the built-up areas and forestland. These six points were measured on November 2th 2017, on November 3th 2017, on November 4th 2017 and on November 5th 2017 with CORS-VRS and CORS-FKP techniques. Static measurements were made 2 hours for points in the forestland and built-up area and 1 hour for other points. Horizontal, vertical angle, horizontal distance, tool height and mark height were measured with total station. Later, in these measurements coordinate differences, distance differences, satellite numbers and RMS values have analyzed and evaluated. It has been noted that the integer ambiguity has been resolved in this evaluation. The obtained horizontal differences between CORS-VRS and Static survey are 1 mm-4.5 cm and the height differences obtained 5-30 cm. And this differences determined that an error can be made with effects of GPS+GLONASS satellites and GNSS receicer's Z-Blade signal processing technology.
