RTK Correction Services in North America: Landscape Overview
RTK (Real-Time Kinematic) correction services in North America include a mix of public CORS networks and private NTRIP-based providers. Public networks—typically operated by state departments or research institutions—offer widespread, often free access via NTRIP, making them a cost-effective entry point. However, their coverage density and consistency may vary by region.
Private providers like Swift Navigation (Skylark) offer subscription-based RTK services designed for broader and more reliable coverage, consistent performance, and higher service quality.
Pros & Cons of RTK Service Types
| Service Type | Pros | Cons |
|---|---|---|
| Public RTK / CORS | Free or low-cost; good for simple surveying; available in many states | Inconsistent coverage; very limited support; outdated hardware in places |
| Private RTK (NTRIP) | Reliable, dense coverage; modern infrastructure; subscriber support | Monthly/annual cost; requires internet connectivity |
Key Takeaways
Public CORS networks are a practical option when budget is tight and coverage exists—but reliability and precision may be limited.
Private NTRIP services offer better accuracy, support, and coverage continuity, making them ideal for professional applications where performance matters.
Connection via internet (NTRIP) is ubiquitous—but it means that a stable data link is essential for uninterrupted corrections.
