摘要： Systems and methods for providing vehicle-centric collision avoidance are disclosed. An example method includes determining a first flight trajectory for a first aircraft, determining a second flight trajectory for a second aircraft, predicting a distance between the first aircraft and the second aircraft at a predicted closest point of approach based on the first and second flight trajectories, comparing the distance to a separation perimeter layer, the separation perimeter layer configured to provide a minimum separation distance from the first aircraft to the second aircraft, and altering the first flight trajectory when the distance breaches the separation perimeter layer.

摘要： Aspects herein describe techniques for synchronizing clocks between two moving platforms using optical signals generated from lasers to measure clock offsets and determine a separation distance between moving platforms. Once the clocks are synchronized (e.g., an offset between the clocks is determined), the moving platforms can share sensor data, location data, and other information which is dependent on accurate timestamps and relative positions. In one aspect, one of the platforms serves as a virtual mirror. That is, the platform transmits a pulse at the same instance a pulse is received, similar to a mirror that reflects incident light. For example, the first platform may transmit pulses which are received at the second platform. The second platform can use optical or electrical components to form the virtual mirror that transmits an optical pulse to the first platform each time a pulse is received at the second platform.

摘要： Aspects herein describe techniques for synchronizing clocks between two moving platforms (e.g., land vehicles, ships, aircraft, and the like) using optical signals generated from lasers. In one aspect, a method for mixing an intermediate signal with a local reference clock in a method of communicating between moving platforms includes mixing the intermediate signal with a sine representation of the local reference clock to generate a first offset error; mixing the intermediate signal with a cosine representation of the local reference clock to generate a second offset error; and combining the first and second offset errors to generate the fine phase offset.
