Powered by Swift Navigation’s Skylark™ Precise Positioning Service, the new dual-frequency system takes virtual fences to the next level and shows 3x more accuracy than any other GPS dog fence on the market.
WOODCLIFF LAKE, N.J., April 16, 2026 — Halo Collar, the leading GPS containment system for dogs, today announced Precision+, a next-generation positioning system designed to deliver superior GPS accuracy for pets. All new and existing Halo Collar 5’s will be updated to include Precision+, which combines Halo’s industry-first L1+L5 dual-band GPS hardware with Swift Navigation’s Skylark™ Precise Positioning Service, a cloud-based GPS correction service powered by a global network of ground reference stations. Precision+ enhances an already market-leading virtual fence system, ensuring even greater accuracy, precision, reliability, and consistency across all environments, while setting the new standard for pet safety.
Independent testing shows Precision+ delivers 3x more accuracy than any other GPS dog fence on the market. The system uses advanced atmospheric modeling to eliminate GPS signal errors and deliver a reliable high-accuracy boundary dogs and their owners can trust anywhere—even in the woods, mountainous terrain, or yards with heavy tree cover.
“Close enough isn’t enough, especially when your dog is near a boundary,” said Ken Ehrman, CEO of Halo Collar. “Halo has always been built applying the most advanced GPS technology to maximize pet safety. Precision+ allows us to push that precision even further, giving pet owners greater confidence that their dog is always safe in the boundaries they set.”
Powered by Swift Navigation’s Skylark™, and delivered over a continuous internet connection, the Halo Collar 5 achieves high-accuracy positioning, adapting in real time to changing atmospheric conditions while maintaining accuracy even in challenging environments. Unlike systems that rely on large antennas and hardware-heavy designs, Halo’s approach combines dual-frequency GPS hardware, cloud corrections, and proprietary software to deliver professional-grade precision in a lightweight collar — bringing automotive-grade performance and reliability to a wearable designed to fit even small dogs.
“In a world of Physical AI, precise location data is the new standard for safety,” said Timothy Harris, CEO of Swift Navigation. “Skylark powers more than 10 million safety-critical devices—from autonomous vehicles to robots and global logistics systems—with high-stakes accuracy. By integrating this same technology into the Halo Collar 5, Halo is leveraging the world’s most proven positioning platform to bring industrial-grade protection to every dog.”
Halo Collar 5 allows pet parents to create and store unlimited wireless fences instantly using the Halo mobile app. The system features built-in training developed by Cesar Millan and uses customizable prevention and encouragement cues, including gentle sounds, voice commands and vibrations, to guide dogs safely within their boundaries.
The Halo Collar 5 retails for $524 and is available through halocollar.com, as well as major retailers including Amazon, Chewy, Best Buy, Petco and Scheels.
