Correction services in Alabama
Alabama 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 DOT network | The state DOT, with reference stations in Alabama. | The account and subscription terms, coverage near your sites, and what it commits to on availability and support. |
| 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. |

Farmland: Alabama had 37,000 farm operations on 8,600,000 acres operated in 2025, and its farms produced 1,183,600,000 broilers. Land leveling, poultry house pads and auto-steer on those farms depend on a correction that holds pass after pass. (USDA NASS, State Agriculture Overview, 2025)
Cotton and peanuts: Alabama farmers had 290,000 acres of upland cotton and 195,000 acres of peanuts planted in 2025. Strip-till, planting and digging on those rows need a line that repeats from one pass to the next. (USDA NASS, State Agriculture Overview, 2025)
Roads: Alabama had 98,632 miles of public road in 2022, 68,170 of them rural. Grading, paving and drainage work on those roads is staked and checked against design. (FHWA, Highway Statistics, Table HM-10, 2022)
