One example includes a mission monitoring system. The system includes a data store configured to store map data associated with a geographic region of interest and a plurality of graphical elements corresponding to at least one mission asset and to mission constraints. Each of the plurality of graphical elements includes a layer assignment associated with one of a plurality of graphical layers. The system also includes a human-machine interface (HMI) configured to facilitate user inputs to selectively activate the plurality of graphical layers associated with the plurality of graphical elements and to display a graphical rendering of the selectively activated graphical layers superimposed over a graphical virtual environment of the geographic region of interest via a display system.

Mission monitoring system

One example includes a federated system manager. Asset adapters receive situational awareness data from a respective plurality of mission assets and convert the situational awareness data into a central data format. Mission constraint adapters receive mission constraint data associated with real-time mission constraints from a respective plurality of mission constraint databases and convert the mission constraint data into the central data format. A mission control adapter receives control data from a mission control station to convert mission control data into the central data format and to provide mission status data to the at least one mission control station for real-time control of the mission. A data model repository maintains a universal data model tracking real-time interactive states of the plurality of mission assets, the real-time mission constraints, and the mission control data. The data model repository also generates the mission status data in real-time based on the universal data model.

Federated system mission management

A middleware abstraction layer (MAL) that can include a plurality of middleware application programming interfaces (APIs). Each of the plurality of middleware APIs can be configured to implement a common programming paradigm for a plurality of different service platforms. The MAL can also include a master application programming interface (API). The master API can be configured to provide a plurality of resources for a mission specific application. Each of the plurality of resources is mapped in a registry to an API call to each of the plurality of middleware APIs. The MAL can further include a control engine configured to load an adapter for a selected a middleware API of the plurality of middleware APIs to service a resource request from the mission specific application. The selection can include examining a configuration file to determine an appropriate middleware API to handle the resource request.

SSC energy buffer circuit includes a switching network and a plurality of energy storage capacitors. The switching network may operate at a relatively low switching frequency and can take advantage of soft charging of the energy storage capacitors to reduce loss. Efficiency of the SSC energy buffer circuit can be extremely high compared with the efficiency of other energy buffer circuits. The SSC energy buffer architecture exhibits losses that scale with the amount of energy buffered, such that a relatively high efficiency can be achieved across a desired operating range. Improvements in SSC energy buffer circuits include, in various implementations, the use of ground reference gate drive, the elimination of a separate precharge circuit through control of at least a portion of the switches of the SSC energy buffer circuit, and/or optimized ratio of capacitance values of two or more capacitors in an SSC energy buffer circuit.
