Compact Gamma-Ray Imager for In-Vivo Gene Imaging
Not Available This proposal describes a plan to design and develop a robust dual frequency GPS receiver for measuring amplitude and phase scintillation under high dynamic conditions. The GPS receiver will also produce navigation solutions at a very high rate and the effects of scintillation on navigation solution may be studied using the proposed system. While the immediate application is in monitoring the equatorial and polar scintillation, the proposed technique, which ensures robust performance in the presence of severe amplitude and phase scintillations, will find numerous applications in providing reliable performance of GPS receivers. The technique can be scaled down to single frequency receivers as well. The novel multiresolution based technique has been proposed to achieve robustness in presence of severe scintillation. During Phase I we propose to perform numerical simulation and demonstrate the feasibility of the technique. We also provide limited hardware based demonstration of the use of GPS receiver for faster data acquisition during scintillation. Further analysis of the hardware/software requirements leading to the development of a complete system is also provided during Phase I.
