The ‘Spartan’ dismounted situational awareness system from Obsidian Technologies is a lightweight system that generates a step-change in Shared Situational Awareness (SSA) and mission effectiveness for dismounted units. It enhances operational tempo and survivability by enabling effective decision-making, while minimizing physical and cognitive burden. Utilizing the Personal Eye System (PES) from Mil-Sistemika provides an optimized Local Operating Picture (LOP), with a near-real-time overview of the battlefield. The inclusion of the VPM-402 Vest Power Manager reduces the physical burden of the system and provides the user with integrated data and power management from a single power source – without the need for separate power and data cables. Using the VPM, the system can also draw power from virtually any power source; allowing the user to extend mission time virtually indefinitely.
