“…Global navigation satellite systems (GNSS) provide global services to both civilian and military users under all-weather conditions and anywhere worldwide (Parkinson et al, 1996;Liu et al, 2012;Krasuski et al, 2019;Sabatini et al, 2015). Global positioning system (GPS) and GLObal NAvigation Satellite System (GLONASS), operating at full capability, are considered to be the fundamental satellite-based navigation systems used for calculating position, time and velocity of the user when four or more satellites are available in view (Chien et al, 1975;Ahmadi, 2011). With the technological advancement, various satellite-based systems, composed of Galileo and BeiDou operated by the European Union and China, respectively, have emerged over the past years, which will offer great opportunities for applications in both scientific and engineering areas (Ogutcu, 2020).…”

Purpose The main aim of this study is to elaborately examine the error correction technology for global navigation satellite system (GNSS) navigation messages and to draw a conceptual decision support framework related to the modernization of the GNSS and other systems. Design/methodology/approach The extensive simulation model developed in Matrix Laboratory (MATLAB) is used to evaluate the performance of forward error correction (FEC) codes such as Hamming, Bose–Chaudhuri–Hocquenghem, convolutional, turbo, low-density parity check (LDPC) and polar codes under different levels of noise. Findings The performance and robustness of the aforementioned algorithms are compared based on the bit length, complexity and execution time of the GNSS navigation message. In terms of bit error rate, LDPC coding exhibits more ability in the robustness of the navigation message, while polar code gives better results according to the execution time. Practical implications In view of future new GNSS signals and message design, the findings of this paper may provide significant insight into navigation message modernization and design as an important part of GNSS modernization. Originality/value To the best of the authors’ knowledge, this is the first study that conducts a direct comparison of various FEC algorithms on GNSS navigation message performance against noise, taking into consideration turbo and newly developed polar codes.
