Determination of the geopotential and orthometric height based on frequency shift equation
Natural Science, 2011 The orthometric height (OH) system plays a key role in geodesy, and it has broad applications in various fields and activities. Based on general relativity theory (GRT), on an arbitrary equi-geo- potential surface, there does not exist the gravity frequency shift of an electromagnetic wave signal.

Global geoid adjustment on local area for GIS applications using GNSS permanent station coordinates
Geodesy and Cartography, 2018 Orthometric heights, useful for many engineering and geoscience applications, can be obtained by GPS (Global Positioning System) surveys only when an accurate geoid undulation model (that supplies the vertical separation between the geoid and WGS84 ...

Selçuk Üniversitesi Mühendislik, Bilim ve Teknoloji Dergisi, 2004 Elipsoidal heights determined by GPS is different from orthometric heights used insurveying applications. Therefore, elipsoidal height determined by GPS is transformed to orthometricheight. It can be used several transformation methods to do this transformation.

International Journal of Advanced Geosciences, 2017 The Global navigation satellite systems (GNSS) has imparted positively on civilian positioning & surveying in the horizontal component in Nigeria for the past two decades. The GNSS receivers’ data are longitude, latitude & elevation. However, the vertical distance measurement have not been fully exploited by geodetic and land surveyors.
