Roadway Pavement Condition Sensor

Not Available The purpose of this proposed effort is to provide a design for a new generation of GPS CRPA antennas which will have superior anti-am performance against a larger number of intentional or unintentional interfering sources than is presently possible. At the same time, this new antenna system (including electronics) will be designed for minimum cost in commercially production quantities. This proposal demonstrates in-depth understanding of the GPS system as it relates and responds to jamming and interfacing signals, and will highlight experience in antenna design, measurement, and fabrication. MRC, allied with Compton Research Corporation and the University of Michigan, provides a unique capability to analyze, design, and (in later phases of this work) fabricate and measure new integrated GPS hardware. MRC is well known for its unique special purpose antenna design and fabrication, but MRC has also designed and built Large Scale Integrated electronics which are actually GPS anti-jam filters. This effort is proposed to investigate antenna configurations, given the satellite, GPS receiver, and interfering signal spatial envelopes. Antenna performance will be predicted by the most advanced computational methods available. An array of designs and cost trade-offs will be delivered.
