Abstract

In this paper, the design considerations of Global Positioning System (GPS) is presented. Simulation issues related to implementing a GPS jamming signal in a laboratory test environment are introduced. These issues pertain to jamming accuracy requirements. Furthermore, important design parameters that may affect jamming system performance are discussed. In addition, an example of the Navigation Laboratory jamming system is given. It addresses fabrication issues, data requirements, error handling, local and remote operations, and how to attain high accuracy and repeatability during the generation and measurement of jamming. Moreover, a new approach for fast detection of GPS signal is presented. The entire data are collected together in a long vector and then tested as a one input pattern. Proposed fast time delay neural networks (FTDNNs) use cross correlation in the frequency domain between the tested data and the input weights of neural networks. It is proved mathematically and practically that the number of computation steps required for the presented time delay neural networks is less than that needed by conventional time delay neural networks (CTDNNs). Simulation results using MATLAB confirm the theoretical computations.
