LASS-2 (Litton Auto Surveyor System-2) Rapid Geodetic Survey System (RGSS). Revision

Abstract

This report presents the progress on the conversion of a standard U. S. Army Position and Azimuth Determining System (PADS AN/USQ-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.
