Precise Autonomous Vehicle Velocity Control

Technology in Practice LLC (TIP) proposes construction of a test bed developed during the Phase I effort and proven to be feasible and cost-effective. The propulsion system and bed assembly allows for adequate power-to-weight ratio to meet the acceleration/velocity/displacement profile requested by HHSTT, and precise autonomous velocity control of the test bed is well within the purview of accepted practice. Therefore, the VMS inertial correlation errors can be quantified at the minimum precision required by HHSTT; i.e., the pitch gyro initial offset versus pitch gyro g-sensitive drift and the pitch gyro fixed drift versus pitch gyro g^2-sensitive drift error sets can maintain adequate decoupling capabilities. A prototype will be constructed during Phase II for demonstration.
