This report considers a mobile vehicle equipped with both an inertial positioning system IPS and a gradiometer. For suitable gradiometer-aiding configurations, the following variables are determined 1 Real-Time vs Post-Mission Data Processing, 2 Presence or absence of Terminal Calibration Data, 3 Continuous Time vs Halted Vehicle Gradiometer Operation, 4 Gradiometer Errors, 5 Zero Velocity and Gradiometer Calibration Stops, and 6 Gyro and accelerometer Errors. This report concluded that one sec or better gradiometer-aided RGSS performance in open traverse is unlikely without vertical deflection end calibration. In addition, the keynote of successful RGSSGradiometer integration will be control and compensation of system bias and low frequency error sources. Author
