Although satellite-based navigation systems are the preferred means for establishing location in “open” terrain, they do suffer shortcomings in areas where the satellites are obscured from the receiver, particularly by man-made structures such as buildings. In short, the performance of GNSS receivers cannot be guaranteed indoors or in densely populated “urban canyon” environments. Wi-Fi positioning is a technique that has been developed to overcome these limitations and augment GNSS-based positioning systems in just such areas.

Topics covered include:

• GPS Update and Industry Developments for GLONASS, Galileo, QZSS, Compass
• GNSS Simulation Fundamentals and Simulation Techniques
• Building a Realistic Test Environment – Including Multipath, Terrain Obscuration & Antenna Patterns
• Capturing and Post Processing Data
• Utilizing Remote Control & Motion
• Differential GPS and Augmentation Systems

Spirent offers an eBook about everything you need to know about record and playback of GNNS RF signals that is available for download on the Spirent website.

The Spirent website offers information, case studies and a video about the new GSS6400 Record and Playback system.

The GSS6400 Record Playback System (RPS) from Spirent is a simple and efficient way to capture real world GNSS signals and replay them in the laboratory. Spirent’s GSS6400 represents the best value and easiest to use solution on the market.
