This paper demonstrates how NovAtel’s GPS/INS technology, SPAN (Synchronized Position Attitude Navigation), can be integrated into an aerial photogrammetry application, with the Inertial Explorer® software package, providing post-processing capability. Flight tests were conducted using a Northrop Grumman LN200 IMU, which is one of four IMU types available for use with SPAN. Attitude accuracy is derived by comparison to an aerotriangulation (AT). Accuracy of ground points is verified by comparison to ground control points. Although this paper is primarily concerned with a photogrammetric application, LiDAR users can expect similar attitude accuracies
