Abstract: The GNSS software receiver has evolved as a promising tool for researchers and developers because of its flexibility and reconfigurability. As modernized GNSS signals have been emerging day by day, the need to adapt the software receiver to address the upcoming challenges of GNSS navigation has become inevitable. The main aim of this work is to assess the existing Global Navigation Satellite System Software Defined Receiver (GNSS-SDR) tool for Indian Regional Navigation Satellite System (IRNSS) signals using a low-cost RTL-SDR front-end. The IRNSS software receiver chain is developed using GNSS-SDR code and framework. GNSS-SDR is an open-source tool developed by the Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) of Spain. This work is useful for carrying out various GNSS-related applications using IRNSS signals in the future and paves the way for further research and development of the IRNSS system by using it as a research/academic tool.
