Linking a GPS Tag to an Asset

If you got your GPS Tag at hand, do the following steps to activate and combine it with your physical asset.

  1. Remove the orange label from the back of the device to turn it on.

  2. Observe that the LED starts to light up for activation and then turns off and remains off.

  3. After a few minutes, the GPS location add-on can be ready to pair with your asset in SFx Asset Management.


    Usually, the LED will turn off after a few minutes. But sometimes it may take up to 1-2 hours depending on the location and cellular connectivity.

Proceed with the following steps to link your asset with a GPS tag.


You need to be an asset administrator to do this.

  1. Log into the SFx Asset Management Portal: https://login.hexagonsfx.com/Account/Login.

  2. Go to the Asset Dashboard and select the laser tracker you want to link to.

  3. Click on the drop-down menu next to the tracker name, then select and click on the GPS item.

  4. Click the Link Your GPS Tag link under Geo-Location.

  5. Type the serial number (SN) printed on the GPS Tag into the input box, and click Confirm.


    A valid serial number contains 13 numeric digits.



    • If the serial number entered is invalid, an error message prompts, “Invalid serial number”.

    • If the GPS Tag has already been linked to another asset, an error message says, “This tag is linked to another asset.”

  6. To unlink a GPS tag, click Unlink next to the entered serial number, and then click Yes, Unlink.

    An unlinked GPS tag can be used to link to another asset for geo-location tracking.



    The battery icon indicates the current battery level of the GPS Tag. You can read the accurate value by hovering over the icon. This value will be automatically updated every hour.

After linking a GPS Tag to a tracker successfully, you’ll see the current geo-location of the asset and its route history within the last 24 hours are both displayed on the map, and the detailed address is also presented under the Serial Number. See the figure below.



When the Geo-location data is older than 2 hours ago, you can find the GPS Tag Last Update time, along with a yellow warning icon (YellowWarningIcon.PNG). This indicates that the current GPS location is not up-to-date. Hover over the icon to see the tooltip. In this case, you can click the Refresh icon at the end of the Geo-Location to get the latest data. See the figure below.


A GPS Tag can also be linked to a tracker probe, which is a type of auxiliary instrument for laser trackers, including Scanners, T-MACs, and T-Probes.

  1. Similarly, activate your GPS Tag first as described above.

  2. Log into the SFx Asset Management Portal: https://login.hexagonsfx.com/Account/Login.

  3. Go to the Asset Dashboard, select the laser tracker that the probe is attached to currently, and click Probes from the asset dropdown menu.

  4. Select and click on the Probes item under the Asset Probes tab.



    ONLY AT930 and AT960 Series are compatible with probes, such as Scanners, T-MACs, and T-Probes. ATS600 series does not provide support for probes.

  5. Select a probe that you want to link your GPS Tag to from the Probe Dashboard.

  6. Scroll down to the Probe Details pane, click on the dropdown icon next to the probe name, and click Geo-Location.

  7. In the Geo-Location dialog, follow the steps described above and link your GPS Tag to the probe.

After linking a GPS Tag to a probe successfully, you’ll see the current geo-location of the probe, and its route history within the last 24 hours are both displayed on the map. In the meantime, its detailed location is also shown in the Probe Details.

In addition, in the Asset Detail View of the tracker that is associated with the probe with a GPS Tag attached, the geo-location of the tracker is displayed, too. You can set up geofences, track route history, and subscribe to GPS Tag notifications for the tracker just like linking the GPS Tag to the tracker.


Only when a probe has not been linked to any tracker with a Lite subscription (you can check the list of trackers that used to link to this probe from the Associated Trackers pane), the route history within a month would be displayed for the GPS Tag. Otherwise, only the last 24 hours of data will be shown on the map.
