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. The FOCUS 35 includes a tracking sensor that uses LockNGo™ FastTrack tracking technology, enabling the instrument to constantly lock onto the prism. 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.
To maintain contact between the FOCUS 35 instrument and the remote observer with the range pole and prism, the robotic solution must include a communication link. The FOCUS 35 uses an integrated 2.4 GHz radio modem as does the Spectra Precision Ranger™ 3 data collector. The 2.4 GHz radio modems provide interference free robotic data communications.
The 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 FOCUS 35 RX model is available in 2’’, 3’’ or 5’’ accuracies. Has a dual battery system hence offering 12hour extended operation through a unique dual battery system, eliminating any need to stop and change battery during a full day’s work. Key features include:
- StepDrive™ motion technology;
- LockNGo™ tracking technology;
- Choice of field software: Spectra Precision Survey Pro™ software on-board and Layout Pro on-board;
- Long-range, reflectorless distance measurement;
