Abstract:

The Loran-C navigation system operates in a complex signal environment that contributes significantly to the systems reduced accuracy and reliability for ground position determination. The paper discusses a hybrid simulation that has been conceived to study this problem. The method used was to develop a signal-processing technique that would recognize and discard corrupt data. The analog computer was used to generate timing pulses and perform 5 mirosecs in-phase and quadrature integrations of the Loran-C signal. The results of the integration were stored in the digital computer for processing. The goal was to achieve a positioning accuracy of 10 ns, an order of magnitude improvement over that of equipment presently available. Author
