Start Date 1: 08/10/2020 8:30 am
Location Course 1: Columbia, Maryland
In this highly structured 4-day short course – specifically tailored to the needs of busy engineers, scientists, managers, and aerospace professionals – Thomas S. Logsdon will provide you with new insights into the modern guidance, navigation, and control techniques now being perfected at key research centers around the globe.
The various topics are illustrated with powerful analogies, full-color sketches, block diagrams, simple one-page derivations highlighting their salient features, and numerical examples that employ inputs from today’s battlefield rockets, orbiting satellites, and deep-space missions. These lessons are carefully laid out to help you design and implement practical performance-optimal missions and test procedures.
