Abstract
Presents an overview of how satellite‐based positioning techniques could be used to develop novel navigational methods for use on mobile robotic platforms. Details are given of the major terrestrial techniques, both internal and external to the robot, which have been traditionally used to meet positioning requirements. A descriptive summary of the global positioning system of navigation satellites (GPS) is followed by an introduction to Galileo, the European project on the development of a comparable system. A small number of examples, either near to market or in use now, are used to illustrate the use of robotic systems that use GPS as a source of 3D absolute position information, but also velocity, attitude and time. Concludes that GPS is likely to become the universal positioning standard for outdoor applications, with future augmentations and developments enhancing the reliability, integrity and accuracy of the system. Nevertheless, in most cases it will still be necessary to use GPS in combination with alternative positioning sensors.
