Geospatial GNSS augmentation to improve vehicle navigation & reliability

GNSS is crucial in mining. Vehicles that operate in open-pit mines must be navigated with precision for both safety and efficiency. GNSS satellite signals can be blocked by the walls and topography of a mine. This reduces the reliability and accuracy, and, therefore, the overall useability of GNSS and automated vehicles. Geospatial GNSS Augmentation and forecasting provide comprehensive predictions of GNSS performance considering the topography of the mine, buildings, and line-of-sight determination of satellites as they orbit. Prediction of GNSS performance enables automated trucking, mining, survey, and fleet tracking to avoid areas of poor coverage or augment to improve performance.
