Precision Geo-Location for Turreted Electro-Optic Sensors

"Innovations & Prototype Engineering has developed a concept for transfer aligning two coordinate frames using what can be described as delta-quaternions. These delta-quaternions can be generated using vectors of almost any quantity that can becharacterized in each of the two coordinate frames. Examples of these vector quantities are inertial linear acceleration, inertial angular rate, and inertial line of sight. These delta-quaternions can be filtered to find a transformation matrix so thatany vector defined in one of the two coordinate frames can be readily expressed in the other.There are existing military systems that use slave inertial measurement units with a full set of navigation equations and a Kalman filter to transfer align the slave to a master inertial navigation system.The phase I effort will focus on characterizing the current absolute pointing error of representative EO/IR systems. The performance improvements of the low impact method using the delta-quaternions will be compared to the more complicated method usingthe full navigation solution.
