High Accuracy
4 cm accuracy delivers the performance autonomous vehicles require, enabling ADAS, V2X and Autonomous Driving use cases that require lane-level positioning.*
Fast Convergence
Skylark reduces initialization times to seconds, ensuring high-accuracy—and high-integrity—positioning is available when you need it.
Enterprise Grade
Skylark is designed for large scale deployments in mass market applications. It supports state-of-the-art security and enterprise management features so you can integrate tightly with your existing infrastructure.
Seamless Coverage
Skylark provides seamless coverage across continents. Skylark processes positioning observations in the cloud and eliminates dependencies on baseline length and negates concerns about base station switching.
Secure
Skylark is a scalable, secure and highly available cloud service delivering a continuous stream of real-time corrections. Skylark supports State Space Representation (SSR) formats for broadcast to millions of devices. NTRIP and RTCM are also supported for compatibility with existing equipment.
Integrity
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. Skylark supports automotive functional safety standard ISO 26262 (ASIL B).
Skylark Cross-Continental Drive Test Results
The Swift test team drove across the country—and back—to demonstrate the true nationwide lane-level GNSS correction coverage of the Skylark precise positioning service.
