SANSA's Navigation unit completed three Satellite Based Augmentation System (SBAS) trials during the months of February and March 2013. Together with the trials, a Lead User Group meeting was held at Hartebeesthoek to confirm user requirements and illustrate the importance of this development to Treasury.
The first trial was held in Heidelberg from 26-28 February 2013 and was based on Precision Farming. Following that, the second took place in Gauteng together with Tracker; and the final GIS trial took place at the Kruger National Park in March 2013. The trials objectives were to illustrate the necessity of an improved navigation system, by comparing the results of a normal GPS to that of the SBAS.
For the Precision Farming trial, a tractor equipped with both the standard GPS as well as the SBAS was driven along specified lines on the farm. To test their accuracy, breaks were taken in between and the 'same' positions resumed – simulating a typical farming pattern. Results from the trial prove that the SBAS unit is indeed more accurate than the current GPS being used; and that the system could potentially eliminate several challenges faced by farmers.
