The SANDUSTER program required a pod instrumented to measure changes in aircraft altitude, attitude, airspeed, and vertical acceleration with respect to time during low-altitude flight. The report describes the pod and its operation. Accuracies of the measurements are as follows Altitude Radar altimeter, Differential pressure transducer, 5 per cent of servo setting, and 100 feet at flight altitudes below 2,000 feet Airspeed, 20 knots Yaw, pitch, and roll rate, 1 degree per second and Vertical acceleration, 5 per cent. Measurement accuracy and reliability could be improved by 1 replacing the existing radar altimeter with a more modern version, and 2 replacing the airspeed and altitude measurement transducers with more modern versions. The use of batteries would make the power system independent of the aircraft carrying the pod. Author
