摘要

To help counter attacks that degrade GNSS capability on combat vehicles, Leonardo DRS developed a modified data-distribution unit computer, the DDUx Ⅱ, with an embedded assured positioning, navigation and timing (APNT) capability the company calls Assured Positioning, Navigation and Timing Converged Computer Embedded & Scalable (AC~2ES). It augments standard military GPS PNT sources with technologies such as anti-jam, anti-spoof, M-code receivers, additional RF sources, vehicle infrared (IR) sensor vision navigation, wheel rotation and inertial measurement units (IMUs). It also offers a choice of multiple timing holdup modules that increase accuracy proportionately with cost. The DDUx Ⅱ and military variants, fielded by the U.S. Army and Marine Corps, allow for integration of APNT functionality with the Battle Management System (BMS). It can provide APNT distribution to all other devices needing PNT within the vehicle without adding to its size, weight and power (SWAP).
