Opis

Radar Systems are quite expensive for tracking mobile targets requiring high precision. In addition, if the target is experiencing high dynamics, there can be substantial uncertainties relating to the tracking capabilities and positioning accuracies. As a cost effective alternative, C/A based GPS receiver can be integrated into the target for tracking and positioning. However, integrating such a low cost C/A GPS receiver into a high dynamic target like the sounding rockets can be challenging. This book gives an in depth analysis into integrating a C/A GPS receiver into sounding rockets. The book starts with a background in C/A GPS technology and sounding rockets. Then it reviews theoretical aspects relating to PLL, DLL, GPS, DGPS, atmospheric models and extended Kalman filter. Next, tracking capabilities of the loops and the changes required are specified. Positional accuracies both in vertical and horizontal directions are simulated by using trajectories from two different rockets (Minidusty and bb12).This guide should be very helpful for the graduate students, practicing electronic engineers, researcher and anyone interested in integrating GPS into high dynamic environment.
