This paper introduces the International Terrestrial Reference Frame (ITRF) transformation software for stations’ three-dimensional coordinates and velocities. The software allow to 14-parameter transformation. The software is written in MATLAB programming language. The software consist of source codes and graphical user interface (GUI) for convenient usage. ITRF versions between 2014 and 1988 can be selected for transformation. Multiple coordinates and velocities of stations can be inputted by the users. There is no restriction for the number of input. The transformation algorithm includes the all necessity terms (most rigorous approach), in this way, high accuracy is maintained. The transformed coordinates and velocities can be saved in word format for desired location.
