“…A software-defined GNSS receiver platform, named as FGI-GSRx (Version 2), has been developed in Finnish Geodetic Institute for the analysis and validation of novel algorithms for an optimized GNSS navigation performance. The basic version of FGI-GSRx is based on an open-source software receiver platform [ 13 ], and it has been adapted to be BeiDou-compatible with a dual-frequency front-end from Nottingham Scientific Limited (NSL) [ 18 ]. The NSL front-end, ‘stereo v2’ is used to capture the BeiDou data.…”

“…Most of these receivers are capable of processing GPS, GLONASS and Galileo signals. Recently, a PC-based BeiDou software receiver was introduced in [ 18 ] albeit with limited algorithmic details on how to acquire, track and process a NH code modulated BeiDou signal. Therefore, in this paper, the authors discuss the implementation issues of a software-defined BeiDou receiver considering the challenges introduced by the existence of NH code modulation in case of BeiDou D1 signal and the higher data rate in case of BeiDou D2 signal.…”

Global Navigation Satellite System (GNSS)-based positioning is experiencing rapid changes. The existing GPS and the GLONASS systems are being modernized to better serve the current challenging applications under harsh signal conditions. These modernizations include increasing the number of transmission frequencies and changes to the signal components. In addition, the Chinese BeiDou Navigation Satellite system (BDS) and the European Galileo are currently under development for global operation. Therefore, in view of these new upcoming systems the research and development of GNSS receivers has been experiencing a new upsurge. In this article, the authors discuss the main functionalities of a GNSS receiver in view of BDS. While describing the main functionalities of a software-defined BeiDou receiver, the authors also highlight the similarities and differences between the signal characteristics of the BeiDou B1 open service signal and the legacy GPS L1 C/A signal, as in general they both exhibit similar characteristics. In addition, the authors implement a novel acquisition technique for long coherent integration in the presence of NH code modulation in BeiDou D1 signal. Furthermore, a simple phase-preserved coherent integration based acquisition scheme is implemented for BeiDou GEO satellite acquisition. Apart from the above BeiDou-specific implementations, a novel Carrier-to-Noise-density ratio estimation technique is also implemented in the software receiver, which does not necessarily require bit synchronization prior to estimation. Finally, the authors present a BeiDou-only position fix with the implemented software-defined BeiDou receiver considering all three satellite constellations from BDS. In addition, a true multi-GNSS position fix with GPS and BDS systems is also presented while comparing their performances for a static stand-alone code phase-based positioning.

“…The receiver was capable of receiving three GPS frequencies in L1, L2, and L5 bands in addition to the signals broadcasted from Galileo's test satellites GIOVE A and GIOVE B. Several groups also presented their contribution on the development of multi-frequency SDRs for GPS and Galileo during the last decade [17][18][19][20][21].…”

Global navigation satellite systems (GNSSs) have been experiencing a rapid growth in recent years with the inclusion of Galileo and BeiDou navigation satellite systems. The existing GPS and GLONASS systems are also being modernized to better serve the current challenging applications under harsh signal conditions. Therefore, the research and development of GNSS receivers have been experiencing a new upsurge in view of multi-GNSS constellations. In this article, a multi-GNSS receiver design is presented in various processing stages for three different GNSS systems, namely, GPS, Galileo, and the Chinese BeiDou navigation satellite system (BDS). The developed multi-GNSS software-defined receiver performance is analyzed with real static data and utilizing a hardware signal simulator. The performance analysis is carried out for each individual system, and it is then compared against each possible multi-GNSS combination. The true multi-GNSS benefits are also highlighted via an urban scenario test carried out with the hardware signal simulator. In open sky tests, the horizontal 50 % error is approximately 3 m for GPS only, 1.8 to 2.8 m for combinations of any two systems, and 1.4 m when using GPS, Galileo, and BDS satellites. The vertical 50 % error reduces from 4.6 to 3.9 when using all the three systems compared to GPS only. In severe urban canyons, the position error for GPS only can be more than ten times larger, and the solution availability can be less than half of the availability for a multi-GNSS solution.
