The Implementation of Modern Geocentric Datum: A Review

Abstract

Abstract. A dynamic datum denotes a coordinate datum in real-time linked with the International Terrestrial Reference Frame (ITRF) in order to provide a dynamic ITRF-like datum to the users. The ITRF is dynamic and updating every few years as its stations’ coordinates consider the motion of earth’s tectonic plate and other deformations. This paper is an effort to review the implementation of dynamic geocentric datum techniques from a few countries. An overview of dynamic geocentric datum implements Malaysia, Australia, New Zealand, Uzbekistan, Israel and Brunei will be summarized to support the future application. Thus, a review consists of a type of datum; datum parameters, reference frame and epoch will be discussed and outlined. This initiative is the significance for the advancement of the future datum development.

A New Redefinition of Geodetic and Plane Coordinates on UTM Geodetic Markers

“…The bigger average magnitude in this study can be explained by the bigger time differences between PMGSN94 and GDM2000 (2016) as compared to that between GDM2000 (2009) and ITRF2014. Nevertheless, this study proved that UTM geodetic markers have displaced as the same things happened on MyRTKNet (DSMM, 2009b;Yazid et al, 2019). Coordinate revision is absolutely required.…”
