What is the positional accuracy of OS Net?
Ordnance Survey achieves an RTK rmse accuracy of 1-2 cm in plan and 3 cm in height (though this is dependent on the user’s equipment and refers to a real-time ‘RTK’ service). The dGPS service will provide from 20 cm to sub-metre positioning (again depending on the user’s equipment). A choice of positional accuracy levels will be available for different applications and for different costs via partner GPS correction services.
