Radionavigation/location requirements for surface users in Canada: present and forecasted equipment uses

摘要

Summary form only given, as follows. The authors estimate the present extent of uses of radionavigation/location equipment and forecast the extent of use by the year 2000. Systems included in this report were grouped into three major types: active satellite systems represented by the GEOSTAR example; passive satellite systems represented by the Global Positioning System example; and ground based systems represented by the Loran-C example. The methodology comprised five phases: documentation review and expert interviews; development of interview guidelines; development of alternative radionavigation-systems-evolution scenarios; interviews with current and potential ground surface users; and data synthesis. Radionavigation systems development scenarios were the object of a number of in-depth interviews with experts. Estimates and forecasts were grouped as follows: public service, goods movements, private, military, agriculture, and other ground surface users.
