A note on frame transformations with applications to geodetic datums

چکیده
Abstract. Rigorous equations in compact symbolic matrix notation are introduced to transform coordinates and velocities between ITRF frames and modern GPS-based geocentric geodetic datums. The theory is general but after neglecting higher than second-order terms it is shown that the equations revert to the formulation currently applied in most major continental datums. We discuss several examples: the North American Datum of 1983 (NAD 83), European Terrestrial Reference System of 1989 (ETRS89), Geodetic Datum of Australia of 1994 (GDA94), and the South American Geocentric Reference System (SIRGAS).

Dynamic Datum Transformations in Australia and New Zealand
Dynamic datums, which account for crustal dynamics, are widely used in Australia and New Zealand, although in many cases users may not be aware that they are using such a datum. The most widely-used global dynamic datums in Australia and New Zealand are the International Terrestrial Reference Frame (ITRF) and the World Geodetic System 1984 (WGS84). The use of WGS84 presents particular challenge...
متن کاملUnderstanding Coordinate Reference Systems, Datums and Transformations
Spatial professionals are required to deal with an increasingly wide range of positioning information obtained from various sources including terrestrial surveying, Global Navigation Satellite System (GNSS) observations and online GNSS processing services. These positions refer to a multitude of local, national and global datums. A clear understanding of the different coordinate reference syste...

In this paper the earth’s magnetic field is simulated precisely while the intensity and direction of the field are verified with one of the standard references for selected points on the earth and the results are compared with some low-order models. In another simulation, the complete model is compared with a common approximate model. The magnetic field in orbital frame is described and to empl...

The Problem: Since the advent of satellite positioning users have been faced with the need to transform coordinates delivered by the satellite based systems to those based on the national geodetic system of the country or area concerned. Transformations between Co-ordinate Reference Systems based on different geodetic datums (sometimes colloquially referred to as “datum shifts”) used within oil...
