Ordnance Survey

Ordnance Survey dates back to 1791, when the Government realised the South Coast of England needed to be comprehensively and accurately mapped. It instructed its Board of Ordnance – the defence ministry of the day – to carry out the necessary survey work. That historic decision led to the mapping of the whole country in detail, and is also the source of the intriguing name ‘Ordnance Survey’.

Today, to the general public, Ordnance Survey (OS) is best known for its paper-printed maps, however it is actually digital mapping data that accounts for around 90% of OS business. Both the public and private sectors need an accurate, reliable geographic framework to help them deliver effective and efficient services and make better decisions. In fact, there are around 650 different recreational and leisure maps alone, together covering every corner of Britain. And even in the internet age, they still sell around 2.5 million paper maps every year.

Leica Geosystems has a long established partnership with Ordnance Survey going back to the days when Leica Geosystems was operating under the Wild name.  Leica Geosystems is the premier supplier of GNSS network RTK corrections, based on the OSNet national reference station network. Leica Geosystems has 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. Since 2006, the correction service, known as SmartNet, has been available only from Leica Geosystems.  This service is live and available as a broadcast correction service to subscribers via GSM or GPRS technology in the UK and is a unique partnership between Leica Geosystems and Ordnance Survey.
