Correction services in Iowa
Iowa 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 a free subscription renewed every two years. | 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. |

Iowa also has its own regional zones, the Iowa Regional Coordinate System (IaRCS), which the state DOT publishes. Set the project, the controller and the correction service to the same frame and zone before the job starts.
