Instead of a diplex filter to separate transmit and receive bands, a terminal device can use an isolation device, such as the splitter/combiner, or a circulator. This provides an ability to use a frequency band for either upstream transmissions or downstream reception, but creates a problem of receiver overload when the isolation device has insufficient isolation or a back-reflection occurs. Use of agile local oscillators allows the direction of the signal in the band to change very rapidly. Likewise a receive frequency can by dynamically reassigned by retuning a LO, which may employ direct digital synthesis. |

An ITCM may include a set of nodes, a set of measures, a logic to control transitions between nodes during a training session, and a logic to establish values for measures during the training sessions. Therefore, the example system may also include an assessment definition logic to define a set of measures to be included in the ITCM and an interaction logic to define a set of interactions to be included in the ITCM. The ITCM may be written to a computer-readable medium. |

Apparatus and method of implementing an augmented reality processed terrain and obstacle threat scouting service
A method of operating an augmented reality processed terrain and obstacle threat scouting service is provided. The method includes using at least one sensor of a monitoring vehicle to monitor terrain and obstacle data. The monitored terrain and obstacle data is compared with terrain and obstacle data in a terrain and obstacle database. A non-validated georeferenced delta is determined when the comparison of the monitored terrain and obstacle data with terrain and obstacle data in the terrain and obstacle database finds non-matching terrain and obstacle data. The non-validated georeferenced delta is transmitted to a ground distribution center, consumer vehicle and/or cloud based server. Non-validated georeferenced delta received at a consumer vehicle is differentiated from other terrain and obstacle data on a synthetic vision display. Non-validated georeferenced delta received at a ground distribution center is validated against at least one other source and validated and non-validated is distributed to subscribing consumers. |

Managing detected obstructions in air traffic control systems for unmanned aerial vehicles
Static obstruction detection and management systems and methods through an Air Traffic Control (ATC) system for Unmanned Aerial Vehicles (UAVs) include receiving UAV data from a plurality of UAVs related to static obstructions; receiving external data from one or more external sources related to the static obstructions; analyzing the UAV data and the external data to populate and manage an obstruction database of the static obstructions; and transmitting obstruction instructions to the plurality of UAVs based on analyzing the obstruction database with their flight plan. |

Drone encroachment avoidance monitor
Disclosed are examples of systems, apparatus, methods and computer program products for locating unmanned aerial vehicles (UAVs). A region of airspace may be scanned with two scanning apparatuses. Each scanning apparatus may include one or more directional Radio Frequency (RF) antennae. The two scanning apparatuses may have different locations. Radio frequency signals emitted by a UAV can be received at each of the two scanning apparatuses. The received radio frequency signals can be processed to determine a first location of the UAV. |
