GPS/IMU Processing

• Airborne acquired data requires a processing step to relate the data sets to a real world coordinate system
• A time-efficient method utilizes a sensor combination of GPS receiver and IMU (Inertial Measurement Unit)
• Post-processing the GPS/IMU data results in the final orientation parameters that consist of X,Y,Z coordinates and three orientation angles for every point (LiDAR) or every exposure (aerial photography)
• The orientation parameters are used to relate the image or point to a location on the ground
