Abstract

The Geodetic Survey Division (GSD)'s primary role is to maintain the Canadian Spatial Reference System (CSRS), ensure its compatibility with current positioning technology, and to facilitate efficient access to it. For over 80 years, GSD has been providing a system for referencing horizontal and vertical coordinates for Canadians. With the advent of GPS and the subsequent demands of a rapidly expanding positioning and navigation community, GSD has upgraded the traditional reference service by developing and operating the Canadian Active Control System (CACS) in collaboration with Geological Survey of Canada. Current plans allow for the Canadian Active Control System to play a key role in the delivery of integrated GPS services across Canada through efficient access to the Canadian Spatial Reference System and by improving the effectiveness and accuracy of GPS applications.
