Spectra Precision FOCUS 35 Series: Datasheet User Guide

OVERVIEW

The FOCUS 35 is a 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. The FOCUS 35 includes a tracking sensor that uses LockNGo™ FastTrack tracking technology, enabling the instrument to constantly lock onto the prism.The FOCUS 35 RX extended operation models feature market-leading battery life.

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

All robotic instruments include:

• A motorized drive system at the instrument
• A tracking sensor to track the range pole and prism
• A communication connection between the instrument and range pole and prism

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 Robotic, RX and LockNGo™ FOCUS 35 models include a tracking sensor that uses LockNGo technology enabling the instrument to constantly lock onto the prism. The benefit of LockNGo technology is the ability to follow the prism at all times and reduces downtime from not having to re-point the instrument on every observation.

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 Ranger™ 3 data collector. The 2.4 GHz radio modems provide interference free robotic data communications.

Once your robotic communications have been established you can control all the functions of the FOCUS 35 from the range pole as you move through the job site making measurements. This makes it possible for a single surveyor to perform high accuracy stakeout, layout or topographic surveys by themselves. From high-order control surveys to topographic data collection or fast-paced construction layout, you can rely on a FOCUS 35, even in harsh outdoor conditions.

The FOCUS 35 total station is combined with 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 Geospatial GeoLock ™ technology to keep locked on target.

The 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.

The FOCUS 35 robotic solution is best described as Simply More Powerful. Packaged in a modern, sleek, and streamlined design, it is easy-to-use, affordable and tough. FOCUS 35 Total Stations are designed to meet all your surveying needs.
