Skylark Cloud-Based GNSS Corrections

Skylark Cloud-Based GNSS Corrections Service

The Skylark Cloud Correction service from Swift Navigation is a one-of-a-kind cloud-based GNSS corrections service that delivers affordable, fast, centimeter-level accuracy and eliminates the complexity of integrating high-precision GNSS technology.



Swift Navigation’s Skylark is a wide area, cloud-based GNSS corrections service that delivers real-time high-precision positioning to autonomous vehicles. Skylark delivers seamless corrections to continents across the globe including the United States, Europe, South Korea, Japan and Australia. Built from the ground-up for autonomy at scale, Skylark enables lane-level positioning, fast convergence times and high integrity and availability required by mass market automotive and autonomous applications.

Skylark uses observations from hundreds of GNSS reference stations around the globe to generate a real-time model of atmospheric and other errors affecting GNSS signals. This correction data is delivered over the Internet to the user where it can be seamlessly accessed anywhere within the Skylark network. Connected users simply turn on their devices to get the correction stream they need.

Skylark is built from the ground up for the needs of emerging autonomous applications, with performance to match—10 cm accuracy* delivers the performance autonomous vehicles require, enabling ADAS, V2X and Autonomous Driving use cases that require lane-level positioning. Skylark reduces initialization times to seconds, ensuring highaccuracy and high-integrity positioning is available when you need it. Skylark is designed for the most demanding safety-of-life critical applications. When used with Swift’s Starling positioning engine, Skylark is capable of delivering Protection Levels (PL) down to 1 m and Target Integrity Risk (TIR) down to 10-7 / hour or better. Skylark supports automotive functional safety standard ISO 26262 (ASIL B).

From its GNSS reference network to its use of the cloud, Skylark is built for scale. Skylark is a secure and highly available cloud service delivering a continuous stream of real-time corrections. Skylark supports Observation Space Representation (OSR) and State Space Representation (SSR) formats for broadcast to millions of devices, reducing data costs and bandwidth. RTCM message format over NTRIP is supported for compatibility with existing equipment. Skylark is designed for large scale deployments in mass market applications, with seamless coverage over continents. It supports state-of-the-art security and enterprise management features so you can integrate tightly with your existing infrastructure.
