AN APPROACH TO DETERMINE MAGNITUDE AND DIRECTION ERROR IN GPS SYSTEM.
Abstract
The Global Positioning System (GPS) allows locating an object in any part of the World with a certain degree of accuracy. Some precision farming activities need to operate with a sub-metric level of accuracy (Grewal et al. 2007). In this article, an approach is introduced to determine, by means of relative positioning, the magnitude and direction of error that the GPS presents. With this error vector it is possible to correct any low cost standard GPS receiver to improve the positional accuracy and to obtain thus more exact distances.Downloads
