Inside the Trimble X7: Deep Dive into Trimble X-Drive Technology 3 3 Trimble X7 Center Unit The center unit mechanical design drives the technical innovations of the Trimble® X7. The protected center unit integrates a survey-grade servo drive with high speed scanning, internal tilt sensors for self-leveling, a calibrated coaxial camera system for fast image acquisition and a laser pointer to facilitate geo-referencing and single point measurements. Figure 1: Trimble X7 protected center unit X-Drive Dual Vertical Deflection System X-Drive is the world's first dual vertical deflection drive system designed by integrating a survey-grade servo drive with a high speed scanning mirror. The concept of using a Total Station's well known vertical servo system on top of a high speed deflection unit for scanning opens new features like auto-calibration, tilt measurements and laser pointer. A total station vertical drive and angle encoder system is still integrated inside the alidade so the complete center unit including the deflection unit and EDM source can be rotated around the trunnion axis in a traditional way like total stations.
