How to Connect to RTKdata in Colorado
Runs on any RTCM v3 hardware: Trimble, Leica, Topcon, Emlid, u-blox, Septentrio and more.
01
Choose a Plan
Pick the subscription that fits your crew, or test the network free for 30 days on real projects from Denver to Grand Junction.
02
Enter NTRIP Credentials
Drop the caster URL, port and mountpoint into your receiver settings. The same credentials work on a paver along I-70 and a drone over the Eastern Plains.
03
Verify FIX
Confirm the fixed solution before you start recording. In open sky, Colorado rovers typically reach centimeter accuracy within seconds, even above 10,000 feet.
Why Colorado professionals choose RTKdata
Accuracy
1-2 cm horizontal, 2-3 cm vertical in open sky. Multi-constellation RTCM 3.x corrections via NTRIP keep your rover on target across Front Range construction sites, Eastern Plains farmland, and high-altitude mountain terrain above 10,000 feet.
Speed
A single NTRIP login covers the whole state. No juggling base stations between the Front Range and the Western Slope.
Availability
99.99% endpoint uptime across the past 12 months with 24/7 monitoring, so corrections keep flowing through mountain weather and summer construction peaks.
Coverage
Coverage spans Denver, Colorado Springs, Fort Collins, Boulder, Grand Junction and Pueblo. Crews crossing into Wyoming, Nebraska, Kansas, New Mexico, Utah or Arizona stay on the same subscription.
Industries Using RTK Corrections in Colorado
From high-altitude mining to Front Range construction, professionals across the state rely on centimeter-level positioning for diverse terrain and industries.
Denver Front Range Construction and Mega-Project Grading
Denver metro has 362 communities under development and major projects including the $905 million Floyd Hill I-70 expansion and Denver International Airport terminal upgrades. Machine control on graders and excavators relies on continuous RTK corrections for cut-fill accuracy across the rapidly growing Front Range corridor.
Molybdenum and Gold Mining Operations
Colorado hosts the world's largest molybdenum mine at Climax (30 million lbs/year) and the Cripple Creek & Victor gold operation (2.7 million oz reserves). RTK-guided drill positioning, stockpile volumetrics, and haul road surveys demand centimeter accuracy across high-altitude open-pit terrain.
CDOT Mountain Highway and Tunnel Infrastructure
CDOT maintains 23,000 lane-miles including the I-70 mountain corridor and Eisenhower-Johnson Memorial Tunnels at 11,112 feet elevation. The Floyd Hill project and ongoing EJMT repairs require precise alignment surveys, grade control, and avalanche mitigation infrastructure placement.
Cannabis Cultivation Facility Site Grading
Colorado's legal cannabis market drives construction of cultivation facilities requiring precise site grading for drainage, utility routing, and regulatory compliance. Facilities demand 2-3x the electrical infrastructure of standard warehouses, making accurate as-built surveys essential for pad preparation and foundation layout.
Vail and Aspen Alpine Resort Infrastructure
Vail, Aspen, and Breckenridge invest hundreds of millions annually in lift installations, terrain expansion, and base area construction. The 2025-2026 season includes Breckenridge's Peak 9 Gondola, Aspen's $80 million infrastructure overhaul, and Monarch's 377-acre expansion, all requiring RTK surveys on steep alpine terrain.
Colorado River Reservoir and Water Infrastructure Monitoring
With Lake Powell at 162 feet below full pool and Colorado headwaters snowpack at 63% of the 30-year median, accurate reservoir level surveys and streamflow monitoring are critical. RTK-equipped survey crews map dam structures, diversion infrastructure, and irrigation canal networks across the Colorado River Basin.

Frequently Asked Questions
What is the most reliable RTK service available in Colorado?
Do I need my own base station to get RTK corrections in Colorado?
No. RTKdata replaces the local base entirely: the rover pulls real-time RTCM3 corrections from permanent reference stations over NTRIP. That includes job sites in mountain counties where setting up a base each morning would cost an hour of daylight.
Which GNSS receivers work with RTKdata in Colorado?
Every device that handles RTCM v3 over NTRIP connects without modification, from survey controllers by Trimble, Leica and Topcon to Emlid, u-blox and Septentrio hardware.
How accurate is RTK positioning in Colorado's mountain terrain?
Expect 1-2 cm horizontal and 2-3 cm vertical accuracy in open-sky conditions. Mountain valleys and canyons may briefly reduce satellite visibility, but multi-constellation tracking (GPS, GLONASS, Galileo, BeiDou) maintains fix availability across most Colorado terrain.
How does RTKdata compare to the Mesa County RTVRN or CDOT CORS stations?
Mesa County operates 33 base stations covering the Grand Junction area, and CDOT provides stations in select regions. RTKdata offers statewide coverage across all 64 counties with a single subscription starting at $40 per month, no agency approval required.
Can I test RTKdata before subscribing?
Yes, 30 days with complete access to the network and all features. No payment details needed and nothing to cancel, the trial ends automatically.
Which coordinate systems does RTKdata support in Colorado?
The network outputs NAD83(2011), Epoch 2010.0. From there your field software handles the transformation into Colorado State Plane North, Central or South, or into UTM.
