  • Publication number: 20180266847
    Abstract: A method is provided for determining corrections to rate data output by inertial sensors of a type typically used in tracking changes in orientation of an object. The present invention also extends to a tracker system incorporating the correction functionality of the present invention. The method makes use of rate data output by inertial sensors associated with the object being tracked and rate data derived from measures of orientation supplied by a non-inertial tracker system also associated with the object being tracked and comprises determining from those rate data corrections for errors due to misalignment in rate data output by inertial sensors, by calculating a mapping between vectors linking points in inertial sensor rate space represented by a sample set of received rate data from the inertial sensors and vectors linking points in a derived object orientation rate space represented by a corresponding and synchronised sample set of derived rate data.

  • Publication number: 20180248982
    Abstract: A tactical network comprises a plurality of assets, at least some of the assets grouped into sub-groups. The assets within each subgroup communicate with each other using a communication protocol. The sub-groups include a first subgroup in which the assets all communicate with each using a first communication protocol and a second sub-group in which the assets all communicate with each other using a second communication protocol which is incompatible with the first communication protocol. Each subgroup is associated with a federated server. The federated server is configured to receive data from the assets, to assess the data to identify significant changes, to convert the significant changes in the data into a common format, compatible with all federated servers in the tactical network, and to transmit, in the common format, to the federated server of another of the subgroups, the significant changes.

  • Patent number: 10049584
    Abstract: A profiling approach for determining a path for an aircraft, using a method comprising the steps of determining at least two waypoints between a starting position and a desired terminal position for the aircraft, determining a path for the aircraft between the starting position and the terminal position, by performing a linear approximation of the heights of the waypoints such that the average height change between waypoints is minimized, and constrained by a maximum climb angle of said aircraft, and performing a linear approximation of arrival times for each of the waypoints and aircraft speeds between the waypoints, constrained by permissible velocity of said aircraft on the slope between the waypoints. In this way, the non-linear relationship between climb rate and speed is approximated with linear equations, because determination of the path between each set of two waypoints is broken into two linear problems.
