Influence of electric power lines on the reception of GNSS-signals in automatic steering systems

Abstract

Global Navigation Satellite Systems (GNSS) are widely applied for positioning and navigation. They play a vital role in the realm of precision farming. As an integral part of automatic steering systems they relieve the driver and reduce costs by increasing efficiency and saving input material such as diesel, fertilizer and chemicals. For some applications the highest achievable accuracy of 2 cm must be maintained permanently. Related to the renovation of the German power grid the influence of underground and above-ground power lines on the performance of GNSS receivers in agricultural applications has been investigated.
