Situation
A large number of markers have to be placed and many components positioned. Control points exist but often get damaged or are covered by equipment, material, vehicles etc. There is a GNSS reference station but, due to obstructions and the type of construction, most points cannot be set out with RTK.
The conventional way
Stakeout with a total station is possible but difficult and time consuming.Traversing is needed to get around obstructions. Temporary points, which can be used for stakeout, have to be established. The work plan has to be revised constantly. Equipment and material have to be moved, which slows down both the survey and construction work.
The SmartStation way
Control points are not required. Simply set up SmartStation wherever it’s convenient. Set up at a first point and fix the position with RTK. Set up at a second point, fix the position, use the first point for orientation, and stake out from the second point. Work in this way establishing pairs or groups of points from which to stake out. As RTK determines the positions, the groups do not have to be connected by total station measurements.
