How to Add Satellite Navigational Accuracy and Stability to Existing Offshore NAV Systems

This paper describes how to employ the accuracy and reliability of the NNSS (TRANSIT) satellite receiver data, as an input to improve the accuracy of a "NAV" SYSTEM which has multiple input data ports. The multiple sensor data from ten or more inputs are accepted by the covariance matrix computational microprocessor, along with the position fix signals from the JMR-2 Doppler Survey Receiving Sub-system. These data are processed to provide multiple outputs for navigation, survey, control and data logging. The helmsperson is provided with a display and the data are recorded on tape. Since different applications require different sensors, this universal design is capable of accepting signals from many sensors with different characteristics.
