Using the GNSS receiver

The TDC6 handheld contain an integrated GNSS receiver, which is set to ensure the best possible performance in the field for data collection and full compatibility with Trimble field and office software.

The receiver supports GPS, GLONASS, Galileo, BeiDou, QZSS, SBAS satellites with 2 - 4 meter positioning accuracy in real time.

To receive signals from GNSS satellites, the handheld must have a clear view of the sky. GNSS positions may not always be available, particularly in or near buildings, in vehicles, or under tree canopy.

For optimal GNSS reception, hold the handheld at 15° from horizontal allowing it visibility of the sky. When collecting point data with a TDC6 handheld, it is recommended that you remain stationary at the point for at least 10 seconds before beginning to log GNSS positions. This allows the GNSS receiver’s internal algorithms to stabilize, and ensures the best possible point feature accuracy.

Using GNSS enables the handheld to determine your location with 2 - 4 meter accuracy in open sky, and enables geo-tagging of photos you take using the handheld's integrated camera (see Using the camera for more information on enabling geotagging and taking photos).

To use the GNSS receiver:

  1. Tap Settings / Location.

  2. If Use location" is Off, tap the slider to turn it On.

A wide range of application software is compatible with the Android 12 operating system and spatial data available through the Google Location Services API, including many GNSS navigation and data collection applications. To access spatial data from the internal GNSS receiver of the TDC6 handheld, third-party applications must support Android Location Services API.

You can use a higher accuracy receiver with the TDC6 handheld. The connection is supported using Bluetooth wireless technology; if you are not using Trimble supported software you will need to enable developer options and Mock locations on the handheld and use Trimble Mobile Manager to configure the external Trimble receiver and feed location services. Trimble Mobile Manager is included in the TDC6 handheld operating system.

The TDC6 handheld also supports the Trimble Catalyst™ service and a Trimble DA2 antenna.

Refer to the documentation for the supported receiver that you are using for more information.
