Raven Connected Enables Real-Time, Centimeter-Accurate Infrastructure Management Using Skylark Precise Positioning Service

To manage aging infrastructure, municipalities and fleet operators have traditionally relied on manual inspections and expensive, specialized survey vehicles. These methods are slow, prone to human error, and often lack the lane-level precision needed to distinguish specific assets in dense urban environments. By integrating Swift Navigation’s Skylark™ Precise Positioning Service with Raven Connected’s AI video telematics platform, everyday service vehicles are transformed into high-precision mapping sensors.

Precise Positioning: Advancing Worker Safety Through Enhanced Location Accuracy

Worker safety demands more than standard GPS. Relying on meter-level accuracy creates significant vulnerabilities in prevention and emergency response. This challenge is overcome using centimeter-level GNSS corrections from Swift Navigation, combined with resilient tracking hardware from Lightbug. This technology enables hyper-accurate geofencing, automated risk mitigation, and guaranteed pinpoint location for first responders.

MikroE + Skylark: Accuracy on any Android Device in Minutes

Connect the MikroE GNSS RTK Click and stream Skylark corrections to an Android tablet to achieve centimeter-level accuracy in minutes. This walkthrough shows you how to visualize real-time high-precision positioning with the Swift Map Demo app and includes a drive-test comparison between corrected and uncorrected GNSS.

Helios Visions Uses Swift Navigation’s Network RTK Service to Power Drone-Based Environmental Cleanup

When a river cleanup project required precise drone mapping without room for base stations, Chicago-based Helios Visions relied on Swift Navigation’s Skylark™ Precise Positioning Service. Skylark’s cloud-based RTK delivered centimeter accuracy along miles of winding waterways, enabling fast, mobile operations directly from boats—without the setup delays of traditional RTK systems.

Troubleshooting The Most Common RTK & NTRIP Issues: A Step-By-Step Guide

RTK corrections provide centimeter-level GNSS accuracy, but performance can be affected by factors such as baseline distance, connectivity issues, multipath interference, and hardware limitations. This guide walks through practical troubleshooting steps to maintain consistent precision. Learn how to identify common issues and ensure reliable, high-accuracy positioning in any environment.

Delivering RTK Corrections over LEO Satellites

Low Earth Orbit (LEO) networks such as Starlink now enable the delivery of real-time GNSS corrections anywhere with an open view of the sky, matching the precision and stability of terrestrial networks while providing a cost-effective, higher-coverage alternative to L-Band.

Skylark Performance Data: Korea Drive Test

Swift Navigation partnered with Korea Telecom (KT) to evaluate the performance of its Skylark™ Precise Positioning Service across a 2,526 km drive spanning cities, highways, tunnels, and mountains. The test, conducted in February 2025, validated the benefits of cloud-based GNSS corrections in Korea’s complex driving environments, delivering highly precise positioning for automotive-grade applications. The results confirmed Skylark’s ability to significantly improve positioning accuracy, achieving a 21x better result than uncorrected GNSS across the entire test, reducing error from 6.28 m to 29 cm.

How GNSS Corrections Are Powering Safer, Smarter Micromobility

Micromobility is entering a new phase—moving beyond early adoption toward sustainable, scalable growth. As the market matures, operators are under increasing pressure to meet safety, compliance, and efficiency standards. High-precision GNSS correction services are emerging as a critical tool to meet these demands. To explore this shift, we spoke with Swift Navigation’s Jochen Bruns, who shares how cloud-based solutions like Skylark™ are helping fleet operators build smarter, more reliable micromobility systems.
