Abstract: Embodiments of a sensor network system provide surveillance capabilities in multiple contexts/environments (e.g., military, commercial, scientific, civic, urban, wilderness, etc.). Network nodes may include devices such as sensors, network routers, network controllers, etc. Network sensors may be configured so that power management objectives are maximized. Network sensors (both individually and as a group) may be capable of intelligent and cooperative information gathering, so that the output of the sensor network does not contain high levels of irrelevant information. The network nodes may communicate among one another via one or more communication links, and in some cases, multiple routes between any two network nodes may be available. The sensor network may include aspects of both high data rate and low data rate network features.

Abstract: An apparatus and method of verifying the trustworthiness of position information from an onboard tracking system on an aircraft. An onboard tracking system message comprising onboard tracking system position information indicating a first position of the aircraft is generated by the onboard tracking system and transmitted to an off board aircraft tracking system via a communications satellite in a satellite communications system. The satellite communications system adds a header comprising transmitter position information identifying a second position for transmission of the onboard tracking system message received by the communications satellite to the onboard tracking system message to form a message. The message is received from the satellite communications system by the off board aircraft tracking system and the first position from the onboard tracking system message is compared to the second position from the header to determine whether the onboard tracking system position information is trustworthy.

Abstract: Work cell and factory level automation require that an Automated Guided Vehicle (AGV) achieve demanding positional accuracy and repeatability relative to a cradle fixture or workstand within a work cell. The AGV makes distance measurements of objects within the work cell using laser scanner sensors. The distance measurements are filtered of objects that are not target features on the cradle fixture or workstand. Systematic or bias errors of the laser scanner sensor are removed from the filtered distance measurements, and a mathematical filter or estimator is applied to the filtered distance measurements using random errors of the laser scanner sensor to generate estimated distance measurements. A map of the target features is then constructed using the estimated distance measurements, wherein the map is used for path planning and navigation control of the AGV relative to the cradle fixture or workstand within the work cell.
