Superior Instrument offers a wide selection of GPS products for Surveying, from static receiver packages, to full RTK systems, and now Network RTK!

SUPERIOR RTK Network Rovers are truly "one-man" systems. With a SUPERIOR RTK Network Rover you no longer need to pay someone to "watch" the base station. Save time and money every time you use one of our rovers, and benefit from a lower initial investment too!

It has never been easier to work with RTK GPS. Whether you work in local coordinates, or State Plane coordinates, the setup is as easy as:

  1. Put the receiver on the pole and turn it on
  2. Turn on your data collector and start job file
  3. "Dial-in" and start working

You can survey monuments all over town, or the state, as easy as getting out of the vehicle and occupying the point. Or use the Rover just like a total station by "localizing" to your assumed coordinates. Setup can be as easy as OCC/BS, or tie into multiple control points for a best-fit solution.

You can reduce your traverse time from DAYS to HOURS!

The farther apart the points are, the more time saved using one of our rovers.
