A graphical user interface application for evaluation of the gravitational tensor components generated by a level ellipsoid of revolution

A graphical user interface software for evaluation of the second order normal gravitational tensor is introduced. Explicit and singularity-free series expansion formulae have been implemented in the software. The normal gravitational tensor components defined in three reference frames may be evaluated with respect to four geodetic reference systems in a regular grid or at arbitrarily located points. The software is primarily developed for applications in satellite gravitational gradiometry.
