The newest component of the Geospatial Reference framework is the BC Active Control System (BCACS) which integrates satellite based positioning, broadcast communication and computer technologies to create a precise and accurate referencing system for the province.
The system currently consists of a network of twenty Global Positioning System (GPS) based satellite receivers strategically located to provide coverage across the province. The BCACS enables post-mission positioning within metres or centimetres to a myriad of land, air and water based navigators.
Access to the BCACS system post-mission data is provided through ftp downloads operated by the Geospatial Reference Unit in Victoria.
