5 Instrument Operational Methods
Conventional Measurements with StepDrive Motor
System
This chapter describes the following instrument operational methods for the FOCUS 35 Total Station:
l
When combined with the application software:
l
When setting/staking out, the instrument calculates and automatically aims towards the
calculated position of the selected point.
l
The instrument will automatically point towards a selected reference target to check for
instrument movement during measurements.
l
Instrument software corrects the collimation / trunnion axis tilt errors in real time.
l
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 Survey Pro software that allows a robotic total station to
perform an aided search for an optical target using an initial GNSS position. The technology greatly
reduces the time to locate and lock onto a target.
The GeoLock technique combines a GNSS position with the FOCUS 35 robotic total station and the
robotic roving operator. The remote instrument can then be directed towards the robotic roving
operator using the GNSS position and a subsequent search is quickly performed to reacquire the target
at the robotic rover.
Robotic Measurement
Combining the StepDrive motor capability with the image-based tracking system and the radio capability
enables the instrument to carry out measurements robotically. This enables a single operator to control
the instrument and carry out measurements or set/stakeout from the rod at the point.
