A Tactical GPS Guidance System

International Telemetering Conference Proceedings / November 14-16, 1978 / Hyatt House Hotel, Los Angeles, CaliforniaThe paper presents results of a design study that defined an optimal (cost vs performance) guidance system that uses the NAVSTAR system. The paper will describe the trades that led to the system configuration. A sequencing receiver (receiver that listens to one satellite at a time) was chosen. This required the navigation system to position the code and frequency of the receiver tracking loops where the receiver switches satellites. Receiver measurements are processed in a U-D formulation of a Kalman filter to update the navigation equations to perform in-flight alignment and parameter estimation of the strapdown gyro biases. Receiver and guidance system performance are presented.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
