Integrated estimation/guidance design approach for improved homing against randomly maneuvering targets

Abstract: Interceptor missiles, designed against aircraft, have substantial speed and maneuverability advantage over their targets. Thus, by exploiting the technological progress, even simple guidance concepts yielded satisfactory performance. For the interception of antisurface missiles, higher guidance precision is required. Using conventional guidance and estimation concepts, existing missile defense systems have demonstrated hit-to-kill accuracy against nonmaneuvering targets. Guaranteeing a similar performance against maneuvering targets can be achieved only if the estimation errors against such targets are minimized. This paper introduces a new, logic-based estimation/ guidance algorithm, that explicitly uses the time-to-go in the estimation process and modifies the guidance law to reduce the consequence of estimation errors. The successful outcome of the new approach is illustrated by an extensive Monte Carlo simulation study.

CARMINAT—An integrated information and guidance system

Abstract: CARMINAT is a European research program conducted under partnership and aimed at integrating a comprehensive information system into motor vehicles. The information may concern the vehicle itself or the traffic situation and other services. It is linked to a navigation and guidance system. Traffic information and services are broadcast by RDS. The route planner takes RDS messages into account to alter the route when necessary. Compatibility with the task of driving is ensured by ergonomic studies and testing. The research phase of Carminat will be followed by large scale pilot programs involving a fleet of vehicles on motorways and in large urban areas.

Development of an integrated fuzzy-logic-based missile guidance law against high speed target

Abstract: How to develop a novel missile guidance law that can act effectively against very high speed incoming targets, such as ballistic missiles, has been a major concern in the defense technique. It has been unveiled recently in the literature that the most effective way for a lower speed interceptor to successfully engage an incoming target with very high speed is to limit the aspect angle between the missile and target flight path to within 180/spl deg/ plus or minus few degrees. On the basis of this requirement, a new integrated fuzzy guidance law is developed in this paper against very high-speed maneuverable targets on three-dimensional space. An integrated fuzzy type guidance law is explored for midcourse and terminal phases. It is shown that the integrated guidance scheme offers excellent tracking performance as well as performance sensitivity with respect to some parametric variations.

Vehicle guidance system using beacon transmissions of destination data

Abstract: A vehicle and destination guidance system is proposed wherein a destination can be input by entering the destination and the street in clear language into a vehicle device. The vehicle device is in communication with a beacon device in which, in addition to the various destinations, street names and the associated coordinates are stored. On demand by the vehicle device, the beacon device selects the associated destination coordinates and transmits them to the vehicle device. Additional data can be transmitted in the transmitted telegram which, for example, contain traffic information or street maps. The system is also usable for automatic toll deductions.

Guidance for human navigation using a vibro-tactile belt interface and robot-like motion planning

Abstract: We present a navigation guidance system that guides a human to a goal point with a tactile belt interface and a stationary laser scanner. We make use of ROS local navigation planner to find an obstacle-free path by modeling the human as a non-holonomic robot. Linear and angular velocities to keep the ’robot’ on the path are dynamically calculated, which are then converted to vibrations and applied by the tactile belt. We define directional and rotational vibration patterns and evaluate which ones are suitable for guiding humans. Continuous patterns for representing directions had the least average angular error with 8.4◦, whereas rotational patterns were recognized with near-perfect accuracy. All patterns had a reaction time slightly more than 1 seconds. The person is tracked in laser scans by fitting an ellipse to the torso. Average tracking error is found to be 5cm in position and 14◦ in orientation in our experiments with 23 people. Best tracking results was achieved when the person is 2.5m away and is facing the sensor or the opposite way. The human control system as a whole is successfully demonstrated in a navigation guidance scenario.
