Leica Geosystems are the premier supplier of GNSS network RTK corrections, based on the OSNet national reference station network. We have worked with Ordnance Survey to install and maintain over one hundred reference stations, from which the OS Net data set is established.

Network RTK is now the method of choice for correcting GNSS positions down to centimetre accuracy where required. The correction service, known as SmartNet, is only available from Leica Geosystems and has been successfully operating since 2005, providing corrections for all users requiring high accuracy positioning. All GNSS systems can exploit the benefits of the SmartNet correction services.
