Configuring GeoLock
Once you have setup your job and total station, you need to power on
your GPS receiver and establish communication.
1. Attach the communications cable.
2. Open the Remote Control or Remote Shot
screen.
3. Set your EDM mode to Track. This is
important for the localization process,
explained later.
4. Tap the satellite icon in the Command
Bar to open a list of GeoLock options.
5. Tap Settings from the list to open the
GeoLock Settings screen. (You can also
access this screen by tapping Job > Settings
> GeoLock…)
6. Make sure the Enable GeoLock checkbox is
checked. If not, tap it to enable it.
7. If you check the Use 3D GeoLock item, the
GPS elevation will also be used when
calculating your GPS position, resulting in
the vertical angle of the total station
changing accordingly when using the
GeoLock feature. Since uncorrected GPS
elevations are less precise than the
horizontal component, using this feature can result in less aiming
accuracy unless surveying in mountainous terrain.
8. Tap to save the settings and close the screen. You are now
ready to collect data and start the localizing process.
If the satellite icon is now red in color , tap the icon and read the
bottom line of the list that opens to see what the problem is. If the
message says No GPS Data, check your communication connection
between the data collector and GPS receiver. If the message says
GeoLock Requires Backsight set, you need to solve your backsight or no
localization solution can be calculated.
