The Modernization of GPS: Plans, New Capabilities and the Future Relationship to Galileo, Keith McDonald (Navtech) 2002 is a useful and accessible program update. Details scenarios re the next 12-18 years and the expected EU program (GNSS/Galileo).
The Global Positioning System: A Shared National Asset, NRC 1995
The Global Positioning System: Assessing National Policies, Rand 1995.
Amy Paige Snyder discusses a number of Pacific Rim issues, and has a useful reference section.
"Raw data freaks" spend time testing GPS receivers and antenna and building a body of vendor-independent insights and characterizations for the rest of us interested in applications of these technologies. I learned a lot from Sam Storm van Leeuwen’s site. He in turn recommends David Martindale (awaiting link), Sam Wormley (awaiting link), Peter Bennett and Karen Nakamura. Karen has many further references.
A High Anitjam GPS-Based Navigator by Gustafson, et al from ION Tech meeting in 2000.
The National Research Council has recommended that the development and operational use of GPS receivers with enhanced antijam (A/J) capability be accelerated.[3] The transmitted GPS signal may be attenuated by trees, buildings, etc., resulting in reduced signal/noise ratio, even without jamming. This loss of signal results in an increase in effective J/S level.
Current Global Positioning System (GPS)-based navigation system performance is marginal in high-interference environments in both civilian and military applications. This paper presents a new approach to solving these problems using a design that may be implemented at low cost in software in existing and future GPS receivers.
