DEVELOPING A REAL TIME ALGORITHM for HEAVE DETERMINATION BASED ON SINGLE FREQUENCY GPS DATA

Organisation: National Research Institute of Astronomy & Geophysics
One of the fastest emerging trends in hydrographic surveying is the use of the vertical component of RTK GPS to determine real-time water level corrections. Accurate heave measurements are a critical component of the measurement of a hydrographic survey vessel’s vertical motion. In the current research we submitte a new algorithm for computing the heave component in real time based on utilizing the ellipsoidal height produced by used single frequency GPS receiver positioning system in the bathymetry process. An evaluation process of the Heave-GPS based on a comparative study with the classical TSS-DMS05 heave compensator is discussed.
