GUI Development of IRNSS Receiver

Abstract

The satellite navigation system is the most important asset for any country in the world. Global navigation satellite system (GNSS) encompasses all global satellite positioning systems like global positioning system (GPS) from the USA, global navigation satellite system (GLONASS) from Russia, Galileo from Europe and BeiDou from China, regional Navigation systems like Quasi-Zenith Satellite System (QZSS) from Japan, and Indian Regional Navigation Satellite System (IRNSS) from India. The Indian Regional Navigation Satellite System (IRNSS) by Indian Space Research Organization (ISRO) consist of a group of seven satellites that cover the Indian boundary and 1500 km extended area near the border. The aim of this work is to develop graphical user interface (GUI) for IRNSS receiver that can use the navigation files in excel format, process it and provide position, velocity, time (PVT) information. It can also plot PVT data and display the coordinates on Google Maps. The GUI is developed with using Python 3.6 with Python Tkinter toolkit. Plot facility of the GUI takes navigation file as input and plots it into six kinds of information, i.e., ground track, position, velocity, altitude, clock bias, and intersystem bias. It also allows to save the plots at desirable locations in the computer. Google Maps facility provides the receiver location on Google Maps with the coordinates.
