Canadian Base Network

Description

With a new focus on positioning from space, Geodetic Survey has created a dynamic infrastructure to serve both present and future needs for positioning. The Canadian Base Network is designed to serve as the new ground segment of monumented survey control in the Canadian Spatial Reference System (CSRS). The Canadian Base Network is a network of pillar monuments with forced-centring plates, positioned three-dimensionally with GPS to centimetre-level accuracy with respect to the Canadian Active Control System (CACS). It provides the link between the existing framework and the CACS. The network consists of an array of pillars at an average spacing of 200 km in the built-up areas of southern Canada, 500 km in the middle regions of Canada, and 1000 km in the northern areas. As well as being a GPS control network, the Canadian Base Network can serve as a monitoring network for deformation studies of the Canadian landmass.
