Radionavigation Systems Evaluation Program for the 1990 Census

Dan Harding, Maurice J. Moroney, Albert D. Frost

Abstract:	Radionavigation systems are being investigated by the Bureau of the Census for possible inclusion in the 1990 Decennial Census procedures. A program has been initiated by the Census Bureau in conjunction with the Transportation Systems Center or the u.s. Department of Transportation to study and evaluate available position location systems which could satisfy Census Bureau requirements for rural residence location and geocoding applications. A study has been completed documenting the strengths and weaknesses of various radionavigation systems in the context of the Census Bureau requirements. The study indicates that LORAN-C and NAVSTAR GPS may be the leading candidates, at this time, for possible use in the 1990 census. Results are presented from a test program conducted in the Georgetown Massachusetts locale to measure the repeatable and absolute accuracy of LORAN-e in a rural environment and develop a data base for the assessment or advanced geocoding processes. A second phase terrestrial test program will be discussed in which it is proposed to make simultaneous measurements of NAVSTAR GPS and LORAN-C performance.
