The End of the Invisible Fence: Why Precise GNSS is the New Standard for Pet Safety

Virtual fencing is replacing buried wires—but standard GPS isn’t precise enough to protect what matters most. Multi-meter drift can stress dogs, break training, and erode owner trust. With sub-meter accuracy, instant convergence, and 99.9% availability, Skylark Dx turns virtual boundaries into dependable, wire-free safety systems built for the next generation of pet tech.

KDDI Modernizes Water Infrastructure Mapping

KDDI is transforming water infrastructure mapping with Skylark Precise Positioning, enabling field crews to capture centimeter-accurate asset data using compact GNSS receivers and smartphones instead of bulky surveying gear. The result: reliable performance even in challenging environments and leak reporting workflows reduced from two hours to just two minutes—bringing high-precision positioning into everyday infrastructure operations.

Unlocking True Lone Worker Safety with Swift Navigation, Lightbug and Quectel

Can wearable RTK devices really last for days on a single charge? Chris Guest, Founder & CEO of Lightbug, joins us to discuss the integration of Swift’s Skylark service and Quectel’s LC29H modules. Discover how this pre-validated tech stack is overcoming multipath challenges to provide a “digital twin” of the worksite for large-scale infrastructure projects.

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.
