Conventional Measurements with StepDrive
Motor System
This chapter describes the following instrument operational methods for the Spectra Precision
FOCUS 35 Total Station:
•
When combined with the application software:
–
When setting/staking out, the instrument calculates and automatically aims towards the
calculated position of the selected point.
–
The instrument will automatically point towards a selected reference target to check for
instrument movement during measurements.
•
Instrument software corrects the collimation / trunnion axis tilt errors in real time.
•
The StepDrive motor system are continuous and endless allowing for rapid repeat manual
pointing of the instrument with no end stops.
Note –
To obtain the correct point location with the instrument, you must aim correctly to the target.
LockNGo Measurement
Combining the StepDrive motor capability with the image based tracking system provides the ability
to carry out LockNGo measurements. LockNGo enables the instrument to automatically lock on to a
prism, and then follow it precisely as it moves. This means that the instrument is taking care of the
pointing, and that position can be continuously updated as the target moves around the jobsite.
LockNGo is especially useful for carrying out rapid site topo measurements and during stakeout using
a conventional two person crew. It is also exceptionally useful for working in poor visibility and
darkness conditions, and for automatically checking to reference targets during measurements.
GeoLock Technology
GeoLock™ technology is a feature of the Spectra Precision Survey Pro software that allows a robotic
total station to perform an aided search for an optical target using an initial GPS position. The
technology greatly reduces the time to locate and lock onto a target.
