Correction services in Wisconsin
Wisconsin crews choose between the state DOT network, commercial network RTK, crowd-sourced base stations, satellite-delivered corrections and their own base.
| Type | Typical operator | What to check |
|---|---|---|
| State network | The state DOT, with access requested through its web application. | Who is eligible for an account, coverage near your sites, whether an availability commitment is published, and support hours. |
| Commercial network RTK | A private provider with stations across several states. | How many correction sources serve your area, the published service level and its remedy, and the term. |
| Crowd-sourced network | Independent owners hosting single base stations. | Distance to the nearest base, station uptime, and how each base was surveyed. |
| Satellite or state-space (PPP-RTK, SSR) | A provider broadcasting an error model without a local base. | Convergence time, accuracy and vertical performance. |
| Your own base | Your crew, on a surveyed point. | The survey of the base point, range, and the time spent setting it up and guarding it. |

RTK Premium delivers NAD83(2011), epoch 2010.0, on every Wisconsin connection, and ITRF on request. Wisconsin uses three State Plane zones under NAD83: North, Central and South. Wisconsin also has a county coordinate system, WISCRS, with its own parameters for each of the 72 counties. Set the project, the controller and the correction service to the same frame and zone before the job starts.
