Correction services in Slovakia
Slovak crews choose between the national mapping agency'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 mapping agency; real-time centimetre corrections are sold by the year or the month, and municipalities, regional authorities and other public budget bodies use them free of charge. | The terms for your sector, coverage near your sites, whether an availability commitment is published, and support hours. |
| Commercial network RTK | A private provider with stations across Slovakia and beyond. | 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. |
Coordinates and heights
RTK Premium delivers ETRS89 (ETRF2000, epoch 2010.0), with ellipsoidal heights. Slovak cadastral and survey data use S-JTSK in the Křovák projection on the Bessel 1841 ellipsoid, with normal heights in the Baltic height system after adjustment (Bpv). Transform ETRS89 to the JTSK03 realisation with the national mapping agency's published seven-parameter key, apply its national correction grid where data sit in the older JTSK realisation, and convert ellipsoidal heights to Bpv with its height reference model, DVRM05. The national realisation of ETRS89 is ETRF2000 at epoch 2008.5, which can differ slightly from the delivered frame, so check against a national control point before cadastral or control work.

Industries using precise positioning or RTK corrections in Slovakia
Farms: In 2023, farms of 50 hectares or more were 20.9% of Slovakia's farms but held 92% of its utilised agricultural area, one of the two highest shares in the EU. Drilling, spraying and harvest guidance across fields of that size depend on a correction that holds pass after pass. (Eurostat, Farms and farmland in the European Union, 2026)
Motorways: Stredné Slovensko, the central Slovak region, had the second-largest motorway expansion of any EU region between 2014 and 2024, with 214 km of new motorway. New carriageways, bridges and tunnel approaches on those routes are staked and checked against design. (Eurostat, 2026)
Rail freight: Rail carried at least 30.0% of Slovakia's freight transport performance in 2022, and transit made up 41.1% of its rail freight, the second-highest transit share in the EU. Track renewals on those freight corridors are measured against design to the centimetre. (Eurostat, Key figures on European transport, 2024)
Forestry: Woodland and shrubland covered 50.2% of Slovakia's total area in 2022, according to the EU land cover survey. Forest roads, timber extraction routes and boundary surveys on that land start from surveyed points. (Eurostat, Land cover statistics, 2025)
Questions about RTK in Slovakia
Which RTK correction service serves Slovakia?
RTK Premium covers Slovakia with 2+ networks in all eight regions and a 99.9% monthly service level in the Eligible Area, and the coverage map shows the networks at any site.
Is there a free RTK network in Slovakia?
The national mapping agency's positioning service sells real-time corrections by the year or the month, and municipalities, regional authorities and other public budget bodies use it free of charge. Community networks host free single base stations of varying quality, so check what each source commits to on availability and support.
Which frame and heights should RTK corrections use in Slovakia?
Use ETRS89, then transform to S-JTSK in the JTSK03 realisation with the national seven-parameter key, and convert to Bpv heights with the national height reference model, DVRM05.
What is the difference between JTSK and JTSK03?
JTSK03 is the realisation of S-JTSK tied to ETRS89 through the national key, while JTSK is the older realisation defined by the national trigonometric network. The national mapping agency's correction grid moves coordinates between the two, so apply it before you match GNSS points to data in JTSK.
How much does RTK Premium cost in Slovakia?
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.
How accurate is RTK in Slovakia?
In a fixed solution under good conditions, RTK Premium reaches under 1.5 cm horizontally and 2.5 cm vertically.
Can I try RTK Premium before I buy?
Yes. The trial runs for 14 days on your own receiver, with full access to the RTK Premium network.
