A LOW COST AUTOMATIC SATELLITE NAVIGATION SYSTEM

The recent evaluation of the TRANSIM low cost satellite navigation system showed that it meets the high seas navigation requirements of the U.S. Merchant Marine through the 1980's and beyond as outlined in the Department of Transportation National Plan for Navigation. When the system was evaluated, it was neither continuous nor automatic. Recent development of a similar system for Antarctic use has shown that the TRANSIM system can be implemented as an automatic, continuously Dead Reckoned system for an increase of less than $5000 in hardware costs, giving a total cost of approximately $15,000. Fully automatic satellite navigation systems are easily within the state of the art of today's technology at production costs of well under $5000 if a data processor is available aboard ship, or available ashore through an appropriate communications link. Thus, use of the low cost approach for navigation with the Navy Navigation Satellite System and a single communications satellite is significantly less expensive than a communications/ navigation system in which the same satellites provide both navigation and communication.
