Abstract:

This report presents the progress on the conversion of a standard U. S. Army Position and Azimuth Determining System PADS ANUSQ-70 to an Auto Surveyor System Dash II LASS-II to a Rapid Geodetic Survey System RGSS. Multiple efforts have been initiated for this contract requirement as follows 1 Perform the non-recurring engineering design for conversion of a LASS-II to an RGSS. 2 Perform the necessary real-time software mechanization changes to enable an RGSS to attain the following performance goals a. Interim Goal Map the gravity disturbance vector to 0.3 sec RMS for the deflection components and 0.5 milligal RMS for the gravity anomaly. b. Long Term goal 0.1 sec RMS for the deflection component and 0.1 milligal RMS for the gravity anomaly as the ultimate goal. 3 In depth investigation of RGSS real-time software definitions, output parameters expansion, and computer simulations for validation of the on-line software mechanization. Hardware changes, real-time software modifications and definitions are contained herein to attain the interim and ultimate performance goals.
