摘要:Abstract(#br)Rigorous modelling of the spherical gravitational potential spectra from the volumetric density and geometry of an attracting body is discussed. Firstly, we derive mathematical formulas for the spatial analysis of spherical harmonic coefficients. Secondly, we present...

摘要:Abstract(#br)A one arc-minute resolution gravimetric quasigeoid model has been computed for New Zealand, covering the region $$25^{\circ }\hbox {S}$$ 25 ∘ S – $$60^{\circ }\hbox {S}$$ 60 ∘ S and $$160^{\circ }\hbox {E}$$ 160 ∘ E – $$170^{\circ }\hbox {W}$$ 170 ∘ W ...

摘要:Abstract(#br)Molodensky G terms are used in the computation of the quasigeoid. We derive error propagation formulas that take into account uncertainties in both the free air gravity anomaly and a digital elevation model. These are applied to generate G 1 terms and their erro...

摘要:Abstract(#br)Variance component estimation (VCE) is used to update the stochastic model in least-squares adjustments, but the uncertainty associated with the VCE-derived weights is rarely considered. Unbalanced data is where there is an unequal number of observations in each...

摘要:Abstract(#br)Global Navigation Satellite System positioning of gravity surveys permits geoid computation via Hotine’s integral. A suite of modifications is presented so that the user can tune the relative contributions of truncation and data errors in a combined solution for...

摘要:Abstract(#br)Present-day continental mass variation as observed by space gravimetry reveals secular mass decline and accumulation. Whereas the former contributes to sea-level rise, the latter results in sea-level fall. As such, consideration of mass accumulation (rather than...

摘要:Abstract.(#br) The AUSGeoid98 gravimetric geoid model of Australia has been computed using data from the EGM96 global geopotential model, the 1996 release of the Australian gravity database, a nationwide digital elevation model, and satellite altimeter-derived marine gravity...

摘要:Abstract(#br)AUSGeoid09 is the new Australia-wide gravimetric quasigeoid model that has been a posteriori fitted to the Australian Height Datum (AHD) so as to provide a product that is practically useful for the more direct determination of AHD heights from Global Navigation...
