Turn Your UAV into a Professional-Grade Mapping Solution with
DG (Direct Georeferencing) from Applanix!
Our GNSS-Inertial technology is designed to reduce the cost and improve the efficiency of aerial survey from UAVs by directly georeferencing each point of sensor data without extensive GCPs (Ground Control Points) or flight line overlap. DG significantly increases the area that can be mapped while reducing flight-time, resulting in much improved productivity.
DG for UAVs – designed and built for unmanned aircraft.
Applanix has brought together its decades of experience in multi-frequency, multi-constellation Differential GNSS and inertial based positioning and orientation with the very best in small-form factor hardware and powerful software, to produce a DG solution for professional aerial mapping on UAVs:
- built for the unmanned aerial environment
- rugged yet lightweight
- powerful but not power-hungry
- custom designed components engineered to tightly integrate all of the enabling technologies
- proven accuracy
- global support
To compute the position and orientation of an imaging payload to a very high degree of accuracy and precision, our DG solutions use multi-frequency, multi-constellation RTK and post-processed carrier phase Differential GNSS tightly integrated with calibrated inertial sensors. For Photogrammetric applications, the Exterior Orientation (EO) of each image is pre-computed before any point-matching or adjustment phase. Unlike a PPK position only DGNSS solution, having the full position and orientation eliminates all issues associated with automatic project set-up, failed point matching and reduced sidelap.
Our DG solutions work with all airborne mapping sensors, including RGB cameras, NIR cameras, Thermal cameras, LiDAR, SAR, Multispectral and Hyperspectral cameras. The georeferencing can be done in real-time, or for highest accuracy in post-mission using the included Applanix POSPac UAV Software.
