A new report describes the benefits growers can experience using NovAtel’s TerraStar-C and TerraStar-L precise point positioning (PPP) technology with a SMART6-L GNSS receiver for automatic steering.

The report, “DLG Test Report 6802, NovAtel SMART6L receiver PPP Automatic Steering Test,” was issued by the German Agricultural Society or Deutsche Landwirtschafts-Gesellschaft (DLG).

DLG promotes technical and scientific progress in the agriculture and food sectors. Set up to test equipment and machinery, the DLG Test Center Machinery and Farm Inputs provide impartial information for practitioners.

DLG awards a DLG-APPROVED quality mark to farm machinery that passes a limited test programme within a DLG usability test. Using a Fendt 828 Vario tractor, combined with the Fendt “VarioGuide RTK” steering system and the NovAtel SMART6-L receiver, steering accuracy was tested using both TerraStar-C and TerraStar-L correction services.

NovAtel’s TerraStar-C correction service provides a 5 cm or less (95%) position accuracy, and TerraStar-L provides a 50 cm or less (95%) position accuracy with a 15-cm pass-to-pass accuracy. The DLG test is designed to measure steering accuracy under various conditions as part of the criteria to receive the DLG-APPROVED quality mark.

The DLG test reported that NovAtel’s TerraStar-C correction service achieved 2-3 cm system steering accuracy on an A-B run on an even track at 8 km/h, and a 3.4 cm accuracy at 15 km/h. The long-term accuracy was reported at 3-4 cm over a 24-hour period. Also, the pass-to-pass error was less than 3 cm over the duration of an hour.

The DLG test reported NovAtel’s TerraStar-L correction service at 17-18 cm accuracy during an hour A-B run on an even track at 8 km/h, and 10-11 cm accuracy on a contour run at 5 km/h. The pass-to-pass error remained below 15 cm for the duration of the tests.

NovAtel’s SMART6-L was awarded the DLG-APPROVED quality mark after successfully completing the PPP autosteering test.
