GPS-derived Geoid using Artificial Neural Network and Least Squares Collocation

Abstract: The geoid heights are needed for determining the orthometric heights from the Global Positioning System (GPS) ellipsoidal heights. There are several methods for geoid height determination. The paper presents a method employing the Artificial Neural Network (ANN) approximation together with the Least Squares Collocation (LSC). The surface obtained by the ANN approximation is used as a trend surface in the least squares collocation. In numerical examples four surfaces were compared: the global geopotential model… Show more

“…This assertion is well documented in literature. For example, ANN has been applied to solve most coordinate transformation problems between global and local datums (Gullu 2010;Gullu et al 2011;Lin and Wang 2006;Mihalache 2012;Tierra et al 2008Tierra et al , 2009Tierra and Romero 2014;Turgut 2010;Yilmaz and Gullu 2012;Zaletnyik 2004), for GPS height conversion (Fu and Liu 2014;Liu et al 2011;Lei and Qi 2010;Tieding et al 2010;Wu et al 2012a), in geodetic deformation modelling (Bao et al 2011;Du et al 2014a, b;Gao et al 2014;Pantazis and Eleni-Georgia 2013;Yilmaz and Gullu 2014;Yilmaz 2013), earth orientation parameters determination (Liao et al 2012;Schuh et al 2002;Yu et al 2015), precise orbital prediction (He-Sheng 2006;Li et al 2014), gravity anomaly estimation (Hajian et al 2011;Hamid and Mohammad 2013;Tierra and De Freitas 2005), geoid determination (Kavzoglu and Saka 2005;Pikridas et al 2011;Stopar et al 2006;Sorkhabi 2015;Veronez et al 2006Veronez et al , 2011, transforming from cartesian coordinates to geodetic coordinates (Civicioglu 2012) and many others.…”

“…It has been a method for local geoid determinations. A number of studies carried out to determine a local geoid (KAVZAOGLU and SAKA, 2005;STOPAR, et al, 2006;VERONEZ, et al, 2006;GULLU, et al, 2011). However, the geoid determined has not been compared with the one approximated by Kriging method.…”
