LongLink™ tab of the Connections dialog

To discover available bases supporting LongLink™ communication with the connected rover; to connect, disconnect, or switch the base that transmit corrections; to remotely access a base receiver using rover's LongLink™.

This tab may have the name Long-Range BT when MAGNET Field is connected to a Sokkia branded GNSS receiver.

This tab is available when LongLink™ is selected as a base and rover receivers' internal radio for kinematic surveys in the Base radio / Rover radio dialog and MAGNET Field is connected to a rover receiver.

Note: LongLink™ technology provides the interference free base-rover communication on 1,000+ ft (300+ m) from the base station and doesn't require an FCC license to operate. LongLink™ communication is supported by the following Topcon GNSS receivers: HiPer SR, HiPer VR, HiPer HR.

The LongLink™ connection automatically establishes by the rover receiver if there is an available base with enabled LongLink™.


  1. To review the details of a connected LongLink™ base transmitting corrections and other available LongLink™ bases:

  2. To connect, disconnect, or switch to another LongLink™ base transmitting corrections to the connected rover:
  3. To remotely access and configure an available base using LongLink™:

Note: The LongLink™ connectivity is also useful to remotely connect MAGNET Field to a robotic total station (PS, DS, GT and GTL series are supported) through a LongLink™ enabled GNSS receiver. Learn more...
