Enabling Autolock, GeoLock

Spectra Geospatial instruments provide Autolock and GeoLock technology for locking onto and tracking remote moving targets. GeoLock technology is GNSS assisted Autolock.

Use:

  • Autolock in servo and robotic surveys or when measuring to other fixed targets. Autolock can also be useful when GNSS positions are of poor quality or unavailable, such as when working underground or in a building.

  • GeoLock in a robotic survey to use your GNSS location to help you lock back onto your prism when lock has been lost. For more information on using GeoLock, see GeoLock.

    TIP – A better GeoLock solution can be computed if the instrument is in TRK mode and locked to the target at the beginning of a survey while moving around for 10-20 seconds when more than 10m from the instrument.

  1. Tap the Instrument icon in the status bar to open the Instrument functions screen.

  2. Tap the Autolock, GeoLock button to enable it. The button is yellow when enabled. Tap the button again to disable the current method.

  3. To configure the target lock method and related settings, tap and hold the button to open the Target controls screen. You can also change the method in the target controls screen.

TIP – When operating in GeoLock mode, press the Toggle GeoLock/AutoLock Fn key to quickly switch to Autolock mode when you need to measure to a target that is not on your survey pole. Press the Fn key again to switch back to GeoLock to lock back to your roving pole. For more information on how to assign Functions keys, see Favorite screens and functions.
