THE EUROPEAN APPROACH TO AUGMENTED SATELLITE BASED POSITIONING SYSTEMS AND THEIR APPLICATION IN PRECISION FARMING

Precision farming is a management process, that involves the development and adaptation of knowledge – based technical management systems with the main goal of optimizing profit. Precision farming can be best understood as a cyclic optimization process, with control elements that measure both quantity and quality. This paper focuses on the GPS, the European Galileo and especially the methods used worldwide for the enhancement of satellite position fixes. To this end we examine the large-scale Satellite-Based Augmentation Systems (SBAS) alternatives, namely WAAS and EGNOS. The specific potential of augmentation systems in precision farming is evaluated against complexity and cost. The paper concludes with the assessment of alternative infrastructures for provision of differential corrections.
