Heave compensation using time-differenced carrier observations from low cost GPS receivers
Blake, Stephen James (2008) Heave compensation using time-differenced carrier observations from low cost GPS receivers. PhD thesis, University of Nottingham.
Vertical reference for hydrographic survey can be provided in two ways: through the use of an expensive and very accurate GPS-aided INS system, or through the classical method of compensating for heave motion measured on board the vessel and tide data taken from a nearby tide gauge. Whilst the GPS-aided INS approach offers significant advantages in terms of accuracy their high cost has prohibited their widespread use within the hydrographic survey industry and the classical method is still prevalent.
