Synopsis

Autonomous vehicles use global navigation satellite systems (GNSS) to provide a position within a few centimeters of truth. Centimeter positioning requires accurate measurement of each satellite's direct path propagation time. Multipath corrupts the propagation time estimate by creating a time-varying bias. A GNSS receiver model is developed and the effects of multipath are investigated. MATLABtm code is provided to enable readers to run simple GNSS receiver simulations. More specifically, GNSS signal models are presented and multipath mitigation techniques are described for various multipath conditions. Appendices are included in the booklet to derive some of the basics on early minus late code synchronization methods. Details on the numerically controlled oscillator and its properties are also given in the appendix.

About the Author

Steven Miller obtained his Bachelors degree of the University of Wisconsin and the Masters and Ph.D. degrees from Arizona State University. He is the founder and CEO of Aperio DSP. He works on the design of algorithms and software tools for GPS, MSK, PSK, AM and FM receivers. He served as a VP Engineering and Director of Technology at Hemisphere GPS. He previously worked at Sicom, Honeywell and Fairchild as a member of the engineering staff. His research interests are in DSP, Digital Communications, GPS systems and their implementations on various platforms including FPGAs. He co-developed advanced multi-frequency GNSS receiver including the analog frequency plan, digital baseband architecture, signal processing chip with hundreds of channels, and software based signal tracking algorithms. He has published in IEEE conferences and journals and he is the co-author of several patents.
