Tracking the target at short range or in areas where the rate of angular change is high always creates a challenge. Having fast servos allows the instrument to track more reliably. The Trimble SPS610 Total Station uses patented Trimble MagDrive fourth generation servo technology, which uses electro-magnets to eliminate direct drive and friction from the servo system. Combined with the USB communications network for the fastest command response time, the system delivers the fastest tracking, fastest turning, most responsive instrument available. Total stations depend on being level to deliver accurate results. When an instrument is knocked, buffeted by wind, or subjected to ground vibration, its level is affected. Dual-axis compensation corrects the angle measurement system for mislevelment.
