Web19 jan. 2024 · In general, a DGPS can achieve accuracies of 1-3 meters, depending on a variety of factors. This means that survey measurements can be conducted with greater precision and reliability. This makes DGPS ideal for applications such as surveying, construction, navigation, mapping, and engineering. Web1 sep. 2024 · The Global Gravitational Models (GGMs) are geopotential models of the Earth consisting of spherical harmonic coefficients published by the Office of Geomatics at National Geospatial-Intelligence Agency (NGA). Three models of EGM are used to calculate geoid undulation of an area. First version is EGM84 with n=m=180.
