Abstract
A Vehicle Localization Augmentation for Dismounts (VLAD), which extends the technology used by dismount localization systems to include the capability of riding and aligning inertial systems to a vehicle. VLAD takes the proven Warfighter's Integrated Navigation System (WINS) and, when appropriate, increases capabilities by investigating aiding sensors, algorithms, and frameworks to align dismount inertial sensors to vehicle inertial sensors. The two focuses of this effort are initialization and maintaining the solution quality. Initialization is the process where an inertial unit calculates sensor biases in an effort to minimize systemic errors in the localization solution. This process is highly related to the sensor being used. High quality sensors, for example, perform a gyrocompassing operation on initialization. Gyrocompassing measures the Earth's rotation and gives the absolute heading relative to the Earth. On man-portable inertial systems, this process can take 15 minutes.
