Productivity with Trimble SX10/SX12 is the added value to our fieldwork. The use of robotics in underground work combined with cycle observations in a trisection to orient the equipment allows us to apply a technique for an accurate result. Subsequently, in Trimble Business Center, each of these trisections can consolidate a network adjustment, which results in a reality survey with the highest precision, rich in information applicable to obtaining products in the control of tunnel and underground space construction.
