Measurements in the coastal zone are carried out using various methods, including Global Navigation Satellite Systems (GNSS), hydroacoustic and optoelectronic methods. Therefore, it is necessary to develop coordinate transformation models that will enable conversion of data from land marine parts one system. The article presents selected issues related integration geodetic hydrographic data. ai...

Coordinate transformation plays an indispensable role in industrial measurements, including photogrammetry, geodesy, laser 3-D measurement and robotics. The widely applied methods of coordinate transformation are generally based on solving the equations of point clouds. Despite the high accuracy, this might result in no solution due to the use of ill conditioned matrices. In this paper, a novel...

A method of computing the 3D viewing transformation which transforms the right-hand world coordinate system to left-hand eye coordinate system is presented. Subject Areas: Computer Graphics.

This article describes currently used analysis strategy and data analysis software for geodetic VLBI. Today’s geodetic observing strategies are shortly presented, and the geodetic VLBI observables and data modeling are briefly discussed. A short overview is given on existing geodetic VLBI software packages and the statistical approaches that are applied. Necessary improvements of today’s analys...

A subset S of vertices in a graph G is a called a geodetic dominating set if S is both a geodetic set and a (standard) dominating set. In this paper, we study geodetic domination on graphs.

The bright stars in the clear night sky with weak background lights should be observed traditional deflection of vertical (DOV) measurement so that DOV cannot under all-weather conditions, which limits its wide applications. An method combining three-dimensional (3D) laser tracking free-fall and multi-GNSS baselines is proposed this paper. In a vacuum environment, 3D technique used to continuou...

Abstract The number of satellites equipped with retroreflectors dedicated to Satellite Laser Ranging (SLR) increases simultaneously the development and invention spherical geodetic satellites, low Earth orbiters (LEOs), Galileo other components Global Navigational System (GNSS). SLR GNSS techniques onboard LEO create possibility widening use observations for deriving station coordinates, which ...

We consider the rational linear relations between real numbers whose squared trigonometric functions have rational values, angles we call " geodetic ". We construct a convenient basis for the vector space over Q generated by these angles. Geodetic angles and rational linear combinations of geodetic angles appear naturally in Euclidean geometry; for illustration we apply our results to equidecom...
