Aircraft guidance with a multi-vehicle network is disclosed. A disclosed example apparatus to determine a position of an aircraft in a contested area includes a direction and distance calculator to determine a relative position of the aircraft to a mobile platform based on a signal transmitted between the aircraft and the mobile platform. The apparatus further includes a position calculator to calculate the position of the aircraft based on the relative position and a position of the mobile platform.

A method and apparatus of controlling movement of an aircraft. A turn path off of a planned route for an aircraft comprising a turn to direct the aircraft to an intercept point on the planned route is determined. A planned route indicator depicting the planned route, a turn path indicator depicting the turn path, and an aircraft position indicator indicating a position of the aircraft are displayed to an operator of the aircraft at the same time on a turn guidance display. Deviation limit indicators for the planned route, the turn path, or both, may be displayed on the turn guidance display. Indicator characteristics of the deviation limit indicators may be changed in response to aircraft deviations from the planned route or the turn path by more than the deviation limits. The turn guidance display is used to control the movement of the aircraft to follow the turn path.

A system and method is provided that displays graphical symbology that enables a pilot to rapidly discern (1) that a neighboring aircraft is a rotorcraft, and (2) whether the rotorcraft is hovering. The provided system and method enables a user to define hovering, by editing a position change (distance) within a predetermined time.

A system and method of operating a system for controlling an unmanned aerial vehicle over a cellular network provides capability for UAV operators to control the UAV without requiring the operator to be within a limited range of the UAV, enabling non-line-of-sight control. A command and control station is communicatively coupled to the cellular network, which is in turn communicatively coupled to the UAV. Video streaming capability is provided, in addition to a modular circuitry unit capable of accepting a wide variety of customizable circuitry units designed for various specific purposes and capabilities.

Methods and systems are disclosed for determining a spatial position of an aircraft, without replying on measurements from the Global Positioning System. Various embodiments are described using a single Secondary Surveillance Radar (SSR), and multiple SSRs.

A UAS may use camera-captured ground feature data to iteratively estimate pose change through a Kalman filter. To avoid excessive drift, the UAS may periodically perform a reset by publishing delta pose and covariance as an edge in a global pose graph, by zeroing out the delta pose and covariance. To further improve global pose estimation, two UASs may share range information and associated pose graph information, thereby providing an additional constraint for each UAS to use in its pose graph optimization.

An example operation may provide receiving, at a server, one or more communications from a drone, determining the one or more communications identify a drone identifier and a current time, determining whether the one or more communications were received within a time window, assigning a token to the identified drone indicating the drone is active, and storing the token as a transaction in memory.
