DGPS for the localisation of the autonomous mobile robots

Abstract

The localisation of the autonomous mobile robot is one of the basic components for the navigation. Especially in case mobile robots are used outdoor the localisation is more difficult than indoor. For the navigation of the cars and bicycles Global Positioning System (GPS) is widely used. The major problem is the accuracy of the measurement. But the most of car navigation systems use the GPS in combination of odometry. The accuracy of the GPS measurement can be improved using additional techniques, like DGPS (Differential Global Positioning System), RTK (Real Time Kinematic) and others. In this paper a study with DGPS and RTK for the localisation of mobile robot in outdoor environment will be reported.
