Blended GPS/DR Position Determination System

S. M. Bennett, D. E. Allen, W. Acker and R. Kidwell

Abstract:	In urban core areas blockage by buildings and severe multipath compromise position location systems based on GPS alone. Dead reckoning navigation, based on a gyroscope and the vehicle odometer, provides continuous position information, but these sensors have calibration uncertainties. Andrew has developed a system which blends the two navigation techniques resulting in a stable, accurate and continuous solution. It consists of a GPS receiver, the Andrew AUTOGYRO@ fiber-optic gyroscope, and an embedded computer. Data from a field trials in Washington, DC and Tampa- St. Petersburg, FL are presented.
