Applications of HDK:

Unmanned Aerial Vehicles (UAVs): Perfect for drones that need to be positioned and navigated precisely, it guarantees precise waypoint following, steady hovering, and trustworthy georeferencing for LiDAR scanning and aerial photography. GNSS receivers improve flight efficiency, particularly in difficult conditions like crowded cities or rough terrain.

Precision Agriculture: allows for accurate tractor guidance, crop monitoring, and effective field mapping at the centimeter level. In order to reduce waste and increase crop yields, GNSS-powered systems make tasks like variable rate fertilizer application, seed planting, and irrigation management easier.

Surveying & Mapping: offers the high-accuracy positioning required for land surveys, construction site planning, and infrastructure development. GNSS receivers enable real-time corrections, faster data collection, and integration with GIS software to create complex maps and 3D models.

Robotics: ideal for robots that need to navigate in dynamic environments and track precise locations. Robotic systems, such as delivery, warehouse, and search-and-rescue robots, can move consistently and effectively even in environments with few visual cues thanks to GNSS data.

Geospatial Data Collection: Perfect for asset tracking applications, environmental monitoring projects, and GIS specialists. Even in difficult or remote locations, GNSS receivers guarantee precise data collection for tasks like infrastructure maintenance, urban planning, disaster response, and natural resource management.
