Modern harvest trials place the highest demands on precision and data security. WINTERSTEIGER's GNSS solutions ensure that weighing and measurement data is clearly assigned to the correct plot at all times. The combine harvester automatically recognizes its current position in the field - regardless of predefined harvesting sequences or changing starting points. Even scenarios such as core threshing in maize are mapped reliably and comprehensibly. The result: maximum flexibility in the harvesting process, significantly reduced operator intervention and a reliable data basis for downstream evaluations. The solution consists of a hardware component for precise positioning and a software component that is seamlessly integrated into our EasyHarvest harvesting software. If required, harvesting positions can also be precisely documented without georeferenced field plans.
