Test with RTKTEST.com
RTKTEST.com runs correction services on receivers at surveyed reference stations and compares each solution with the station's known coordinates. One 15-minute session compares up to three services, so you can put RTK Premium next to the service you run today before you switch.

Correction services in Australia
Australian crews choose between state government CORS networks, the national positioning programme, commercial network RTK, crowd-sourced base stations, satellite-delivered corrections and their own base. They differ in coverage, in what they commit to on availability, and in what happens when the stream stops.
| Type | Typical operator | What to check |
|---|---|---|
| State government CORS network | A state government, often as a subscription sold through value-added resellers. | Coverage near your sites, 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 whether one account works in every state you cover. |
| 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
Australian survey and GIS work runs in GDA2020. RTK Premium delivers GDA2020, epoch 2020.0, on every Australian connection. The Map Grid of Australia projects GDA2020 into 6-degree UTM zones, MGA2020 zones 49 to 56 from west to east, so project coordinates into the zone your site or project specifies. Convert ellipsoidal heights to the Australian Height Datum (AHD) with AUSGeoid2020, the national geoid model. GDA94 coordinates sit about 1.8 m from GDA2020, so convert legacy GDA94 data with the national conformal plus distortion grid before you compare it with new work. Set the project, the controller and the correction service to the same datum and zone before the job starts.

Industries using precise positioning or RTK corrections in Australia
Broadacre crops: The ABS shows 61.1 million tonnes of winter broadacre crops sold in Australia in 2024-25, and wheat makes up 34.8 million tonnes of it. Sowing, spraying and harvest across those paddocks run on guidance that has to hold pass after pass. (Australian Bureau of Statistics, Australian Agriculture: Broadacre Crops, 2024-25)
Beef cattle: Australia had an estimated 27.6 million beef cattle at 30 June 2025, and Queensland held 13.5 million of them. Fencing, water points and yards on large properties are laid out and checked by position. (Australian Bureau of Statistics, Australian Agriculture: Livestock, 2024-25)
Construction: Total construction work done in Australia reached A$82,515.9 million in the June quarter of 2026, in seasonally adjusted terms. Earthworks, setout and as-built checks on that work run to centimetres. (Australian Bureau of Statistics, Construction Work Done, Australia, Preliminary, 2026)
