WISCONSIN / GNSS CORRECTIONS

WISCORS field guide

Start with WisDOT’s account and network information, then verify the settings against your job control.

Checked September 11, 2026. The linked FAQ is dated February 27, 2023; verify current settings with WisDOT. Independent guide, not an official WisDOT manual.

Get set up

  1. Request access through the WISCORS web application. Use the connection details supplied after approval, including the account name, address, port and available mountpoints.
  2. Have your equipment provider match the correction format and receiver configuration. A mountpoint is the named correction stream selected in the rover’s connection settings.
  3. Arrange separate logins for rovers used simultaneously. Keep the organization’s contact email current.
  4. The 2023 FAQ describes alignment to NAD83(2011), epoch 2010.00. Check the current station information and your project reference before relying on that description.

If a connection fails

For account or network questions: wiscors@dot.wi.gov (official contacts). Send error text and equipment details; omit passwords.

Before accepting the points

Use the common control-check and CSV/LandXML handoff checklist. WISCORS corrections do not automatically put an imported design into your job’s WISCRS county grid or establish the required elevation reference.

A connection or fixed solution is not an acceptance test. Compare observations to trusted project control using the project’s tolerances.
