ANALYSIS OF COMMON QUALITY PROBLEMS IN COORDINATE TRANSFORMATION BETWEEN REFERENCE COORDINATE SYSTEM AND GEOCENTRIC COORDINATE SYSTEM [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
In the working of the existing reference coordinate system transformed into the coordinate system of the geocentric coordinate system, many experts and scholars have in-depth research on the transformation methods such as geodetic control point results ...

ALGORITHM AND APPLICATION DEVELOPMENT FOR PRECISE AND ACCURATE TRANSFORMATION OF LIDAR POINT CLOUDS INTO NATIONAL COORDINATE SYSTEMS OF ROMANIA USING OFFICIAL EQUATIONS AND QUASIGEOID MODEL [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
The LiDAR point clouds are usually processed in Universal Transvers Mercator projection. The transformation to a national coordinate system is frequently made with low accuracy with the help of the generic transformation implemented in the actual ...

WTLS iterative algorithm of 3D similarity coordinate transformation based on Gibbs vectors

open access: yesEarth, Planets and Space, 2020
The 3D similarity coordinate transformation is fundamental and frequently encountered in many areas of work such as geodesy, engineering surveying, LIDAR, terrestrial laser scanning, photogrammetry, machine vision, etc.

Določitev položajev cerkvenih zvonikov v koordinatnem sistemu D96/TM ( = Position determination of church belfries in the D96/TM coordinate system) [PDF]

open access: yesGeodetski Vestnik, 2018
In the old coordinate system, church belfries often served as reference points in detail surveying. Consequently, their coordinates were regularly maintained in the geodetic databases of the old coordinate system.

Coordinate systems, geodetic datums and coordinate transformation

open access: yesVojnotehnički Glasnik, 1999
This article makes an effort to define some types of coordinate systems and geodetic datums. Also it points out the importance of making connection between the local datum in which all state maps are prepared and the geocentric datum in which GPS works.

Analysis and optimal individual pitch control decoupling by inclusion of an azimuth offset in the multi-blade coordinate transformation [PDF]

open access: yesWind Energy, 2018
With the trend of increasing wind turbine rotor diameters, the mitigation of blade fatigue loadings is of special interest to extend the turbine lifetime. Fatigue load reductions can be partly accomplished using Individual Pitch Control (IPC) facilitated

Induction Motor Hybrid Coordinate Transformation Model and Its Application

open access: yesJournal of Harbin University of Science and Technology, 2018
For the strong coupling problem between the rotor current and the air gap flux in the expression of the electromagnetic torque expression of the induction motor,the hybrid coordinate transformation is adopted by the αβ0 transformation and the MT0 ...

Misconceptions About General Relativity in Theoretical Black Hole Astrophysics [PDF]

open access: yes, 2010
The fundamental role played by black holes in our study of microquasars, gamma ray bursts, and the outflows from active galactic nuclei requires an appreciation for, and at times some in-depth analysis of, curved spacetime.

Are Simple Real Pole Solutions Physical? [PDF]

open access: yes, 2000
We consider exact solutions generated by the inverse scattering technique, also known as the soliton transformation. In particular, we study the class of simple real pole solutions. For quite some time, those solutions have been considered interesting as
