Characterization of a low cost GPS RTK system

Abstract

In recent decades, the robotic community has increasingly adopted the use of GPS-RTK sensors to accurately estimate the location of mobile robots in outdoor environments. In this work, the characterization of a low-cost GPS-RTK system is presented. From the assembly of the base and mobile units, corrected position data was acquired in real time by the same RTK system under different physical dispositions, update rates and environmental conditions, and a statistical study of the results obtained was subsequently presented.
