Solar-powered tracking for dry trailers, containers and other transport assets.
Complete, uninterrupted visibility across the supply chain — for stronger ROI, better asset utilization and expedited cargo delivery, virtually anywhere in the world.

Built for uninterrupted visibility
Reliable location reporting
Uninterrupted visibility of trailers and containers as they move along the supply chain. The device reports precise asset location at regular intervals — on trips, dormant in yards, and when an asset begins or ends a move. Global LTE falls back to multi-band 3G and 2G where 4G isn't available, with optional satellite backup for added reliability.
Simplified installation
Installs easily and quickly on all types of transportation assets, including those with narrow vertical or horizontal corrugations. VIACHAIN's Field Support Tool mobile app simplifies device and sensor configuration, and facilitates troubleshooting in the field.
Advanced solar technology
A solar panel leverages the latest technology for long-lasting battery life and fast charging. Shipped fully charged, the GT 1220 holds its charge for at least 6 months before installation, and in limited light still delivers multiple messages per hour without failure.
Flexible deployment
Available as a turnkey solution with a customizable application — powerful reports, dynamic dashboards, advanced analytics and two-way commands. Or integrate data feeds directly into third-party Transportation Management Systems and proprietary enterprise applications via APIs.
