Book excerpt: Biezard's pioneering work on the Global Positioning System (GPS) is reflected in the chapters on two types of navigation: GPS and Inertial Navigation System (INS), augmented by discussions of Newton's laws applied to navigation, uncertainty in navigation, and the role of Kalman filters in the integration of aircraft avionics systems. He applies the American Institute of Aeronautics and Astronautics' approach to aeronautical engineering courses by combining interrelated disciplines with computer exercises. The Aided Inertial Navigation Systems software (Windows and DOS) supports the final chapter exercises on error analysis and Kalman filter simulation. Appends discussion questions and web sites.
