Correction services in New South Wales
Crews in New South Wales choose between the state government's CORS network, the national positioning programme, commercial network RTK, crowd-sourced base stations, satellite-delivered corrections and their own base.
| Type | Typical operator | What to check |
|---|---|---|
| State government CORS network | The state government, through industry resellers; direct subscriptions go only to station hosts, education and research. | Coverage near your sites, the datum on each port, whether an availability commitment is published, and support hours. |
| National positioning programme | The national geodetic agency, with free single-base real-time and archive data across the country. | Distance to the nearest base, 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 GDA2020, epoch 2020.0, on every New South Wales connection. Mainland New South Wales spans MGA2020 zones 54, 55 and 56, the Map Grid of Australia's 6-degree UTM zones on GDA2020, and the state also endorses a GDA Lambert projection for state-wide GIS and mapping. Convert ellipsoidal heights to the Australian Height Datum (AHD) with AUSGeoid2020, the national geoid model. GDA94 coordinates sit about 1.8 m south-west of GDA2020, so convert legacy GDA94 data with the NTv2 conformal plus distortion grid the state recommends. Set the project, the controller and the correction service to the same datum and zone before the job starts.
