BCACS-providing geo-spatial reference through GPS network
Al Barwani, Tariq
The 21st century has started out with a very positive outlook for the GPS community and its applications around the world. There has been great progress; from the elimination of selective availability in 2000 to a combination of modernizing of GPS signals, by implementing L2C and L5, through planned launches of new GPS satellites and a new GNSS from coming out of Europe called Galileo. It is an important for all nations to develop and update their current geo-spatial referencing infrastructure in order to be compatible with these changes and support and utilize them to develop their nation as a whole. This can be achieved by implementing a network of continuously operating reference systems (CORS) across a country to provide reliable, accurate and compatible GPS data. In the Province of British Columbia in Canada, that CORS system is called the British Columbia Active Control System (BCACS). The BCACS is operated by Base Mapping and Geomatic Services (BMGS) and a few municipal agencies. The BCACS is extensively used through out the urban and rural areas of the province; users range from municipal bodies and industries to land surveyors, all requiring access to accurate and reliable geospatial data. The network is and ever improving and expanding entity that provide quality geospatial services to the industries that drive and shape the provinces economy as a whole. This paper discusses the elements of a successful GPS network and how to utilize it in order to satisfy users and to further improve services to keep up to date with the ever-changing technologies.
