Correction services in Connecticut
Connecticut 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 and the state university, currently free and open to the public with a registered 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. |
