The Global Navigation Support System (GNSS) Version 2 provides critical positioning, tracking, communication and response support to Military Deployment & Distribution Command aligned Army Reserve units. The equipment combines the ability to safely collect real time GNSS data in austere environments using a broad spectrum of DOD handheld devices with a supplemental ability for rapid response rail and mobility systems protection. The 8300-050-0200 provides technical training and readiness oversight (TTRO) to all personnel performing deployment support and secure movement control for rail and maritime functions. Multiple correction sources within the GNSS hub provide precise, real-time data to ARMY personnel while features such as the integrated binocular/Laser Rangefinder increase functionality and decrease weight; GPS; Bluetooth 4.1 base.
