The RASANT service has provided a valuable service improving the GPS positioning in Catalonia for 15 years. It has made possible to reduce the autonomous GPS positioning error from hundred meters to a metric precision in real time throughout the territory. The discontinuation of selective availability (SA) in May 2000 and the entry of the EGNOS service in October 2009 have made the availavility of the RASANT service a not significant improvement for the autonomous GPS positioning. Taking into account these assessments, we inform that RASANT service will be disconnected next January 1st 2011.
