Spectra Precision 35-3 3" Robotic Total Station

The Spectra Precision FOCUS 35 Series is a new range of motorized total stations providing high speed, accuracy and precision in measurement. The FOCUS 35 robotic instrument moves the power of the observer from the instrument to the range pole, improving efficiency. The speed of observation and precise positioning of the FOCUS 35 Robotic Total Station is provided by patented StepDrive™ motion technology, which controls the horizontal and vertical motion of the motors, eliminating the need for traditional motion locks.

he FOCUS 35 is available in 1”, 2”, 3” or 5” accuracies and is controlled by the Spectra Precision Survey Pro™ field software using an onboard Windows CE touchscreen interface. The FOCUS 35 is also designed to be controlled externally by Spectra Precision Ranger™, Nomad™, or T41® data collectors running Spectra Precision Survey Pro field software,  Spectra Precision Layout Pro or Spectra Precision FAST Survey on the Ranger or Nomad.

The speed of observation and precise positioning of the FOCUS 35 robotic total station is provided by patented StepDrive ™ technology. StepDrive controls the horizontal and vertical motion of the motors, so there is no need for traditional motion locks. Using the motorized drives it is possible to precisely turn to, and repeat angle measurements. This results in quick and reliable measurements which substantially increases your staking productivity.

The FOCUS 35 total station is combined with Spectra Precision Survey Pro field software, providing you with world class software solutions for any surveying application. An example of these features includes a unique robotic software technology that can be used when associating the FOCUS 35 with a low-cost GPS receiver and Survey Pro software. This combination of technologies allows the user to take full advantage of the Spectra Precision GeoLock ™ technology to keep locked on target.

The Spectra Precision GeoLock technique allows a robotic total station to perform an aided search for an optical target using an initial GPS position. The remote instrument can then be directed towards the robotic roving operator using the GPS position and a subsequent search is quickly performed to re-acquire the target at the robotic rover. This technique greatly reduces wasted time, improving your field work efficiency.
