This book presents fundmentals of orbit determination--from weighted least squares approaches (Gauss) to today's high-speed computer algorithms that provide accuracy within a few centimeters. Numerous examples and problems are provided to enhance readers' understanding of the material.
Covers such topics as coordinate and time systems, square root filters, process noise techniques, and the use of fictitious parameters for absorbing un-modeled and incorrectly modeled forces acting on a satellite. Examples and exercises serve to illustrate the principles throughout each chapter. *Detailed solutions to end-of-chapter exercises available to instructors.
Graduate students and researchers in aerospace engineering, astrodynamics, geodesy, and oceanography.
Researchers in the aerospace industry and related research laboratories interested in satellite navigation and control.
