Abstract:	The success of US Global Positioning System (GPS) energized the development of other Global Navigation Satellite Systems (GNSS) and triggered a broad research on extending the coverage of satellite positioning systems to indoor, urban canyon, underground, deep space and other areas where GPS signals are weak and/or distorted by various phenomena such as propagation loss, signal blockages from buildings and foliage, multipath effects and jamming. To operate the GNSS receivers in such complicated environments one should employ flexible multimode receivers which adapt to signal variations and availability. Such an advanced research may not be conducted without convenient development kits and testing platforms which significantly facilitate researcher efforts. Recently software defined GPS/GNSS receiver concept gained popularity as such a development tool because it permits a complete access to algorithmic library for experimenting with various approaches and continuously upgrading receivers without hardware updates. While software receiver is a very flexible and versatile platform, the development cycle for real-time systems can be long and platform dependent. This paper proposes Labview-based real-time receiver platform which may reduce the development time and facilitate testing by exploiting a standard development environment.
