GeoLock
GeoLock is a feature that uses a GPS receiver to calculate your
position so while working robotically, if the total station loses lock of
the prism, it can quickly turn to the location of the prism based on the
GPS position and then automatically perform a search to lock back
onto the prism.
GeoLock is available when using a Trimble or Geodimeter robotic
total station, along with a GPS receiver that outputs a NMEA signal.
Most inexpensive consumer handheld GPS receivers will output the
required signal.
Communication between the data collector and GPS receiver can take
place using a compatible data cable, Bluetooth, or a direct connection
such as with a CompactFlash GPS receiver.
All of the GeoLock features and settings are accessed
while in the Remote Control or Remote Shot screens.
Specifically, you will use the GeoLock button and the
satellite icon in the Command Bar, which changes
color to indicate different situations related to GeoLock,
as described below.
If you tap on the satellite icon , a list will open to
access other GeoLock-related screens. At the bottom of
this list is a message indicating the current GPS status,
which coincides with the color of the satellite icon as
follows:
(gray icon) Off: GeoLock is not enabled.
(yellow icon) On - Collecting Data: GeoLock is active
but a localization solution does not yet exist.
(red icon) No GPS Data or GeoLock requires Backsight set: No
NMEA data is available or the backsight has not yet been set.
(green icon) On - Ready: GeoLock is active and a localization
solution exists.
