Real-Time GIPSY (RTG) and Real-Time Kinematics (RTK): An Integration Approach on Naval Oceanographic Office (NAVOCEANO) Survey Ships and Hydrographic Survey Launches (HSLs)

Abstract:	The demand for three-dimensional position accuracy in the hydrographic community is ever increasing with technology evolutions in the area of Global Positioning System (GPS). The application of Real-Time GIPSY (RTG) and Real-Time Kinematics (RTK) techniques have made it possible for the Naval Oceanographic Office (NAVOCEANO) to meet International Hydrographic Organization (IHO) horizontal and vertical position requirements for Order 1 and Special Order hydrographic surveys. NAVOCEANO has integrated a combined RTG/RTK receiver into its Mission Survey Systems on survey ships and hydrographic survey launches (HSLs). The NAVOCEANO system consists of a Shipboard RTG/RTK Subsystem and a Land-Based Station Subsystem. This system has been deployed on NAVOCEANO’s fleet of survey ships and HSLs and is integrated with the onboard Position and Orientation System for Marine Vessels (POS/MV) and Integrated Survey System (ISS-60) as a primary source of horizontal and vertical position data. This paper describes the integration approach taken for the Shipboard and Land-Based RTG/RTK subsystems and discusses “real world” performance.
