4. ON-DEMAND REMOTE CONTROL FUNCTIONS
The Remote Control System works as follows. A laser is emitted from the laser projection port on the
Remote Controller. The total station rotates until its beam detector receives this beam. In this way the
total station is able to detect the position of the Remote Controller. This operation is called "Turning".
With the Remote Control System it is possible for a single operator to perform measurements,
unaided, at multiple measurement points.
The Remote Controller incorporates a Bluetooth unit which allows simultaneous communication with
both the total station and a data collector.
Electronic compass
The Remote Controller is equipped with an electronic compass. Using the Earth’s magnetism,
this compass can detect the Remote Controller’s horizontal angle from magnetic north.
The current angle is compared with that for the previous measurement to estimate the direction
in which the Remote Controller moved following the previous measurement. By then taking into
account the aspect of the telescope the Remote Controller can instruct the total station regarding
the quickest rotation direction to the prism.
The onboard electronic compass was calibrated before being shipped from the factory. A
function within the compass will automatically perform any necessary calibration in response to
changes in the magnetic field.
Auto Pointing and Auto Tracking
When Auto Pointing is performed, the total station analyses the image of the prism in the field of
view and moves the telescope to sight the center of this prism. When used in conjunction with
the Auto Tracking function, the total station will then "track" the prism as it is moved to the next
measurement point. When the prism has been "lost" due to an obstacle in the line-of-sight or
operation has been interrupted, the Remote Control System allows you to quickly resume
operation where you left off.
