Last updated: April 14, 2026. GPSnet.dk, HxGN SmartNet, and Trimble VRS Now do not publish pricing. Contact each provider for current rates. GPSnet has the densest station network in Denmark. SmartNet stations are controlled and approved by SDFI, the Danish geodetic authority. RTKdata's 28 stations produce longer average baselines than either GPSnet or SmartNet, which may affect accuracy in areas far from a station.

How to Connect to RTKdata in Denmark

Three steps from signup to centimeter positioning on any Danish job site.

Choose a Plan

Select a subscription or start the 30-day free trial. No credit card is needed. Test corrections on your Jutland farm fields, Zealand construction sites, or Funen survey projects before choosing a paid plan.

Enter NTRIP Credentials

Add the server address, port, and AUTO mountpoint to your rover or field controller, and set coordinate output to ETRS89/UTM Zone 32N. Setup takes under five minutes on any RTCM3-compatible device.

Verify FIX

Check your receiver display for a fixed RTK solution. Denmark’s flat, open terrain produces a fix within seconds across most of the country. Centimeter-level accuracy applies from the northern tip of Jutland to the islands of Zealand and Bornholm.

Industries Using RTK Corrections in Denmark

Danish agriculture, offshore energy, and infrastructure construction each depend on centimeter-level GNSS positioning for different reasons.

Agriculture

Denmark is the world's largest pork exporter, shipping 90% of production to 140+ countries (Agriculture & Food Council, 2024). Precision technology already covers 81% of Danish farmland. EU CAP eco-schemes and Action Plans for the Aquatic Environment mandate GPS-documented manure and fertilizer application, and the EU's 2030 pesticide reduction target will make RTK spray guidance near-mandatory.

Offshore Wind

Denmark operates 16 offshore wind farms with 2.7 GW of installed capacity and 700+ turbines (DEA, 2025). Kriegers Flak generates 604 MW in the Baltic Sea, and the 1 GW Thor project in the North Sea commissions in 2027. GNSS supports turbine foundation staking, cable route surveys, and marine vessel positioning during installation campaigns.

Construction

Denmark plans to invest DKK 157.6 billion ($22.8B) in transport infrastructure by 2035 . As the first country to mandate BIM on public projects (2007), digital delivery is required for all regional work above EUR 2.7M. RTK-guided machine control for excavators, graders, and pavers delivers centimeter tolerances on megaprojects like the 18 km Femern Belt tunnel.

Land Surveying

Denmark's 5 regions and 98 municipalities generate ongoing demand for cadastral, boundary, and topographic surveys. All work references ETRS89/UTM Zone 32N horizontally and DVR90 vertically. The flat Danish landscape, with a highest point of just 170.86 m, provides near-ideal sky visibility for GNSS receivers, producing fast RTK fixes from Jutland to Bornholm.

Maritime and Ports

The Port of Aarhus handles 10+ million tonnes per year and roughly 60% of Denmark's container traffic across 1,300 m of quay (UNISCO). Copenhagen Malmo Port processes 194,000+ TEUs annually. RTK positioning supports hydrographic surveys, dredging operations, automated container yard equipment, and vessel docking guidance at both facilities.

Drones and Mapping

Danish regulations permit beyond-visual-line-of-sight (BVLOS) drone flights for commercial operators meeting EASA standards. RTK-equipped UAVs collect photogrammetric data for crop health monitoring across 2.6 million hectares of farmland, wind turbine blade inspection at offshore sites, and progress tracking on linear infrastructure projects like the Odense-Kauslunde railway corridor.

Coastal Erosion Monitoring

The Kystdirektoratet (Coastal Authority) runs regular survey campaigns across Denmark's extensive North Sea and Baltic coastline. Climate adaptation plans for low-lying areas require centimeter-accurate shoreline measurement as sea levels rise. RTK-equipped drones and survey teams measure cliff retreat and beach volume change to feed national flood defense planning and Femern Belt coastal assessments

Controlled Traffic Farming

Permanent tramlines confining all machinery to fixed GPS-guided paths reduce soil compaction on 80% or more of each field. Denmark's flat terrain and high-value export agriculture make controlled traffic farming particularly viable, improving soil structure, water infiltration, and crop yields. RTK provides the 2 cm repeatable accuracy needed to hold the same tramlines season after season.

GNSS in Denmark's Projects: Offshore Wind & Femern Belt

The Femern Belt Fixed Link, an 18 km immersed tunnel from Rodby to Puttgarden opening in 2029, relies on GNSS to position each precast element to millimeter tolerances during immersion, driving RTK demand along Denmark’s alignment corridor through 2028 (GPS World). Offshore, Denmark targets 13.2 GW of wind by 2030, up from 2.7 GW today (Danish Energy Agency). Land-based RTK covers nearshore cable and substation work, but accuracy degrades beyond 20-30 km from the nearest reference station, so far-offshore sites like Horns Rev (14-44 km out) need PPK workflows or marine PPP as supplements.

Why Danish Teams Choose RTKdata

Flat-Terrain Accuracy

Denmark's highest point is 170.86 m. Minimal terrain obstruction means near-ideal satellite visibility across the entire country. Open farmland, coastal plains, and low-rise urban areas all produce a fast RTK fix with 1-2 cm horizontal and 2-3 cm vertical accuracy under normal conditions.

Instant Self-Service

Sign up online, receive NTRIP credentials, and start receiving corrections within minutes. No dealer appointment, no hardware bundle, no waiting period. TDC 5G reaches 99.7% of Denmark (Danish Technological Institute, 2023), so mobile data for NTRIP is available on nearly every site.

Nordic Cross-Border Included

One subscription covers Denmark plus Sweden, Norway, and Finland at no extra cost. Projects along the Oresund, across the Great Belt bridge approaches, or between Jutland and southern Sweden work seamlessly without separate accounts, extra fees, or NTRIP credential reconfiguration in the field.

ETRS89 / UTM32N / DVR90 Workflow

Corrections deliver ETRS89, the datum underlying UTM Zone 32N used for all Danish survey and mapping work. Your receiver converts directly to UTM32N (EPSG:25832) on the fly. For DVR90 orthometric heights, apply the DVR90(2023) geoid model from in your controller software.

Frequently Asked Questions

How much does RTK cost in Denmark?

RTKdata charges $40/mo (~275 DKK) or $400/yr (~2,750 DKK) with Nordic cross-border coverage included. GPSnet.dk, HxGN SmartNet, and Trimble VRS Now do not publish pricing and require contacting sales or a dealer. GPSnet offers 1-year, 2-year, and 3-year subscription tiers. Industry sources suggest Danish commercial RTK subscriptions from dealer networks typically run 4,000-8,000 DKK per year depending on the tier and contract length.

Which RTK correction services cover Denmark?

Four RTK networks operate in Denmark as of 2026. GPSnet.dk (Geoteam) runs approximately 80 reference stations at 30-35 km spacing and is the densest commercial network. HxGN SmartNet maintains 57 stations approved by SDFI. Trimble VRS Now provides Nordic coverage through its dealer network. RTKdata connects to 28 stations in Denmark (plus 20,000+ globally) at $40/mo (~275 DKK) with instant activation and a 30-day free trial.

Do I need my own base station for field work in Denmark?

Network RTK removes the need to bring a base receiver to each job site. Corrections stream from permanent reference stations to your rover via NTRIP protocol over any mobile data connection. TDC 5G covers 99.7% of Denmark (Source: Danish Technological Institute, 2023), so NTRIP connectivity is available on nearly every field, construction site, and roadway in the country.

Does RTKdata support ETRS89 and DVR90 in Denmark?

RTKdata delivers corrections in ETRS89 via the AUTO mountpoint. Your receiver or field controller projects these into UTM Zone 32N (EPSG:25832), the standard horizontal system for all Danish survey and mapping work. Heights arrive as ellipsoidal values. To convert to orthometric heights in DVR90, load the DVR90 geoid model in your controller software (Source: SDFI). See the full datum guide at docs.rtkdata.com.

Can I use RTK corrections offshore in the Danish North Sea?

RTK accuracy degrades with distance from the nearest reference station, and offshore wind farms like Horns Rev sit 15-40 km from the coast. At those distances, corrections from any land-based network provide reduced accuracy compared to onshore work. For cable route surveys and vessel positioning near shore, network RTK remains usable. For turbine foundation staking at greater distances, combining RTK with PPK post-processing or a marine PPP service gives more consistent results.

Does one subscription cover Denmark and neighboring Nordic countries?

A single RTKdata subscription includes Sweden, Norway, and Finland at no extra charge. The same NTRIP credentials work on a dairy farm in Jutland, a construction site in Malmo, or a forestry road in central Norway. Cross-border projects along the Oresund, across the Great Belt, or between Jutland and southern Sweden do not require separate accounts or additional fees.

Is there a free trial for RTK corrections in Denmark?

RTKdata offers a 30-day trial with full access to all 28 Danish stations and the 20,000+ station global network. No credit card is required. GPSnet.dk provides a 7-day demo that requires your own SIM card. HxGN SmartNet and Trimble VRS Now trial availability varies by dealer. The 30-day window gives enough time to test corrections across multiple Danish job sites before committing.

Centimeter Positioning Across All of Denmark

From Jutland’s flat farmland to Zealand’s construction corridors and the offshore wind fields of the North Sea, one NTRIP connection delivers RTK corrections across 43,094 km2 of Danish territory. Connect your receiver, confirm a fixed solution, and begin working at 1-2 cm accuracy within minutes.
