RTK Premium delivers network RTK corrections in Greece in ETRS89 (ETRF2000, epoch 2010.0) over standard NTRIP. In a fixed solution it reaches under 1.5 cm horizontally and 2.5 cm vertically. 2+ networks serve most of Greece, including the mainland and most of the Peloponnese, so smart failover takes over when a network drops there, and the 99.9% monthly service level applies in the Eligible Area the coverage map shows. The map shows fewer networks on Crete and the eastern Aegean islands, so check those sites first, and run the 14-day free trial before you commit.

RTKTEST.com compares up to three correction services against a surveyed point in one 15-minute session, and the 14-day trial runs on your own receiver at your own sites.
Greek crews choose between the national cadastre's positioning service, commercial network RTK, crowd-sourced base stations, satellite-delivered corrections and their own base.
| Type | Typical operator | What to check |
|---|---|---|
| National positioning service | The national cadastre; users pay a one-off registration fee per licence, and real-time corrections are charged by connection time. | The cost for your expected hours, coverage near your sites, whether an availability commitment is published, and support hours. |
| Commercial network RTK | A private provider with stations across Greece. | How many correction sources serve your area, the published service level and its remedy, the term, and whether a trial is offered. |
| 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. |
RTK Premium delivers ETRS89 (ETRF2000, epoch 2010.0), with ellipsoidal heights. Greek cadastral and survey data use GGRS87 coordinates on the national TM87 grid, and the national cadastre's positioning service works in HTRS07, its own realisation of ETRS89. Transform to GGRS87 with the cadastre's official transformation model, which applies a seven-parameter transformation and then a grid of residual corrections, rather than with a seven-parameter set alone. HTRS07 and ETRF2000 can differ slightly, so check against a national control point before cadastral or control work, and convert ellipsoidal heights to orthometric heights with the geoid model your project specifies.
Orchards: Greece had 14% of the EU's olive tree area and 8% of its 426,000 hectares of citrus plantations in 2023. New groves are set out from surveyed lines before planting, and their irrigation follows the same lines. (Eurostat, Agricultural production: orchards, 2023)
Vineyards: Greece was the only EU member state with vines grown for raisins in 2020, and those vines made up 37.4% of all vines in the country. Vine rows are planted and wired along surveyed lines. (Eurostat, Vineyards in the EU, 2020)
Forestry: Woodland and shrubland covered 60.0% of Greece's total area in 2022, and only Finland, Sweden, Slovenia and Croatia had a larger share in the EU. Forest roads, firebreaks and boundary surveys on that land start from surveyed points. (Eurostat, Land cover statistics, 2022)
Renewables: Renewable sources generated 60.9% of the electricity consumed in Greece in 2025, by provisional figures, one of six EU countries above 60%. Solar parks, wind farms and their grid connections are laid out and piled from surveyed points. (Eurostat, Renewable energy statistics, 2025)
RTK Premium covers most of Greece with 2+ networks and a 99.9% monthly service level in the Eligible Area, and the map shows fewer networks on Crete and the eastern Aegean islands. The coverage map shows the networks at any site.
The national cadastre's positioning service takes a one-off registration fee per licence and bills real-time corrections by connection time. Community networks host free single base stations of varying quality, so check what each source commits to on availability and support.
Use ETRS89, then transform to GGRS87 coordinates on the TM87 grid with the national cadastre's official transformation model. Convert ellipsoidal heights to orthometric heights with the geoid model your project specifies.
A single set of national parameters between ETRS89 and GGRS87 leaves residual errors that the official correction grid removes. Use the official model for cadastral and control work, and check against a national control point.
Prices depend on the number of devices, the term and the product, and we quote them after a short call. The 14-day trial needs no payment.
In a fixed solution under good conditions, RTK Premium reaches under 1.5 cm horizontally and 2.5 cm vertically.
Yes. The trial runs for 14 days on your own receiver, with full access to the RTK Premium network.
