4. ON-DEMAND REMOTE CONTROL FUNCTIONS
The On-demand Remote Control System works as follows. A laser is emitted from the laser projection
port on the RC-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 RC-Controller. This operation is called
"Turning".
With the On-demand Remote Control System it is possible for a single operator to perform
measurements, unaided, at multiple measurement points.
The RC-Controller incorporates a
Bluetooth
unit which allows simultaneous communication with both
the total station and a data collector.
&
Electronic compass
The RC-Controller is equipped with an electronic compass. Using the Earth’s magnetism, this
compass can detect the RC-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 RC-Controller moved following the previous measurement. By then taking into
account the aspect of the telescope the RC-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 SRX/NET 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 On-demand Remote Control System allows you to quickly
resume operation where you left off.
