Correction services in Arizona
Arizona crews choose between a state agency's CORS network, commercial network RTK, crowd-sourced base stations, satellite-delivered corrections and their own base.
| Type | Typical operator | What to check |
|---|---|---|
| State CORS network | A state agency, which distributes a real-time stream in NAD83(2011), epoch 2010.0, to public agencies, private users and the public after registration. | Registration terms, 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. |
Coordinates and heights
RTK Premium delivers NAD83(2011), epoch 2010.0, on every Arizona connection, and ITRF on request. Arizona uses three State Plane zones under NAD83: East, Central and West. The state agency's CORS network uses the same frame and epoch for its station coordinates, which helps when a job ties into its stations. Set the project, the controller and the correction service to the same frame and zone before the job starts.
