To configure MAGNET Field for use with Skybridge, follow the steps in this article. Note that this configuration shows the use of Skybridge with a non-Topcon network. It will work equally as well with Topnet Live.
From the Main menu, select and press Configure.
Select and press Survey.
Press Select from Library.
Press Add.
Enter the Name for the configuration.
Select Network RTK for the Type.
Select VRS for the Corrections.
Select NTRIP 2.0/1.0 for the Protocol.
Press Next.
Select the Manufacturer of your receiver. Press Next.
Select the type of connection.
Select the Receiver Model.
Enter the Elevation Mask. If you are using an external antenna, make sure that you select it. If not, make sure it matches the Receiver Model.
Enter the H.I. of the antenna.
Press the blue M button in the upper left corner.
Select Receiver Settings.
Check the Enable Skybridge box, and select Lband for the Skybridge delivery.

- Controller
Then determine how the corrections will get to the device. Press Next.
Select the network that you wish to work from. Press Next.
Check the Automatic Rover Pos box.
Press Next.
Configure the TILT Settings to your liking. Press Next.
Select Fixed, PPPF and PPPN as the Solution type for both Precise and Quick. This selection allows the use of the RTK Fixed solution when it is available. After the Precise Point Positioning (PPP) solution converges, if you lose connection to the network, the PPPF (PPP Full) and PPPN (PPP Normal) solutions become available and allow collection of data to continue.
Press Next.
Select Fixed, PPPF and PPPN as the solution type for Auto Topo. Press Next.
Set the Stake Settings tolerances to your liking. Press Next.
Select Fixed, PPPF and PPPN as the Solution type for both Precise and Quick on the Stake Settings screen.
Press Next.
Configure the Grade Stake Marking settings to your liking. Press Next.
Set the Staked Point Icon to your liking. Press Next.
Configure the Point Naming settings to your liking. Press Next.
Enable all constellations and tracking. Tracking is subject to OAF authorizations. Tracking may be affected by the version of Skybridge that you have purchased. Skybridge is GPS and GLONASS only. Skybridge Pro is all constellations.
Press Next.
Configure the Advanced screen. Choose Extrapolation for the RTK Position, and check the Multipath Reduction box.
Press Next.
Configure the Miscellaneous screen to your preferences. Press the green check mark.
Press the green check mark. Press Home.
Select and press Connect.
Select the rover receiver you wish to connect to. Press Select.
Enter the PIN if your receiver requires it. Press Connect.
Select and press Connect.
You are connected to the receiver, and the receiver icon will show up beside the Home button.
Wait as the controller contacts the network you selected.
Select the mount point that you use on your network. Please note that this works equally well with Topnet as well as non-Topcon networks.
Press Connect.
A message will display: Base station data was updated from corrections.
Press Close.
Press Home.
Select and press Survey.
Select and press Topo.
The Topo screen will show a fixed solution with good residuals.
Press the blue M button.
Select Status.
On the Status screen, select the System tab.
Scroll to the bottom of the screen, and note the Skybridge Status reads Base Estimation.
You can collect topo shots using the network RTK while the PPP solution converges.
In about 25 to 30 minutes, the Skybridge Status will change to Ready.
At that point, if the network connection is lost, your topo screen will show a PPPN or PPPF solution.
You can continue to TOPO at a reduced precision for 20 minutes.
When the connection to the RTK network is restored, the base station data will be updated.
You can then resume your network RTK survey.
It will take a few minutes for the Skybridge Status to show Ready again. It is a good practice to stay in the area where the network came back until the Skybridge is ready. You should be able to switch back and forth freely once base estimation is complete as long as you don’t power down the receiver or go far enough away from your VRS base station.
When Skybridge is ready, you can lose your network connection and work with the PPPF or PPPN solutions.
