A phase measurement radio positioning system for indoor use

Abstract

I present here the detailed design for a low frequency radio navigation system called the Building Positioning System (BPS). This system is designed to work indoors, where the microwave radio signals of the Global Positioning System (OPS) cannot be received. Potential applications for this system range from asset tracking, security, and human-computer interface, to robot navigation and the management of services as diverse as medical care and postal delivery. I first present the issues surrounding its conceptual design and then describe in detail the component level implementation of the prototype BPS system, which I have designed and built but not yet tested as a whole. I also discuss the test procedures which will accompany the deployment of that prototype system in its initial configuration in its test building, as well as further research that is required to make the system scalable and manufacturable.
