# Skylark Precise Positioning Service Discussions

Skylark is Swift Navigation’s cloud-based GNSS correction service, improving positioning accuracy from several meters to centimeter level for products deployed at scale. It’s available in three variants, so you can match accuracy, coverage, power and cost to your application: - Skylark Nx RTK: network RTK with 1–2 cm accuracy, for robotics, drones, survey, mapping and agriculture - Skylark Cx: PPP-RTK with 3–7 cm accuracy and uniform continent-wide coverage, ISO 26262 certified to ASIL-B for automotive and safety-critical applications - Skylark Dx: DGNSS with sub-meter accuracy, optimized for small, battery-powered devices such as IoT trackers, wearables and handsets Unlike services that interpolate between reference stations, Skylark models the ionosphere and troposphere across each region, combining machine learning trained on nearly 10 years of data with physics-based constraints. The result is consistent accuracy between stations and during ionospheric activity. Every station is monitored in real time, and suspect data is excluded automatically before it reaches devices. Key features: - Largest partner ecosystem in the industry, with 30+ validated partners, including Quectel, Telit Cinterion, Deutsche Telekom, NVIDIA, and Skydio - Service Quality Indicator to predict performance at any location before deployment - Portal and API provisioning for fleets of any size - Redundant, AWS-hosted infrastructure with 24/7 monitoring - Encrypted, signed correction streams and ISO 27001 certification - Trusted by 10M+ vehicles and devices Start with a free 14-day trial on your own hardware.
