LOCALIZATION USING FILTERED DGPS

Arun Kumar G C, Varalakshmi K R

Abstract: In this paper, localization of the robot is achieved by considering two Global Positioning Systems (GPS) or DGPS. Differential Global Positioning System (DGPS) is interfaced with MBED with the help of Zigbee protocol. For accurate localization of mobile robot DGPS is preferred. Filters are used to remove the erroneous noise from the data obtained from GPS. Low pass IIR filter for DGPS is realized. The project work discusses each of these approaches for localization in Outdoor environment. The above algorithm is implemented on MBED Platform. Simulation results are extracted using Matlab.

Keywords: localization, Outdoor environment, Low pass IIR filter, DGPS, MBED
