Overview

A Single Data Layer, Delivering Real‑Time Connectivity

STAR TRAX® is a multi-network, tactical command and control (C2) integration software designed to unify space-to-ground data flows into a single, mission-ready operational picture. Built on our proven SNC TRAX® FoS architecture, STAR TRAX delivers a scalable and interoperable solution for real-time connectivity across heterogeneous sensors, radios, ground stations and space-based assets—accelerating decision timelines from hours to minutes.

‍

Through deep integration with critical government networks, STAR TRAX provides operators a more robust and relevant operational picture, delivering critical situational awareness across the space domain.
