摘要： Systems and methods for receiving ADS-B messages in environments where multipath propagation corrupts the messages or blocks the reception of the messages. An exemplary system combines RF signal processing and digital signal processing techniques to make it possible to receive ADS-B messages in the presence of multipath reflections from nearby structures and/or farther out structures. The system uses an array of horizontally spaced antennas. The RF signals from the antennas are combined by the receiver so as to form a set of beams with different azimuth antenna patterns to increase the probability that the multipath does not combine destructively with the line-of-sight path in at least one of the beams. This effectively removes multipath reflections where the delay of the multipath relative to the line-of-sight path is less than 100-200 nanoseconds. The system is also configured to remove multipath reflections with greater delays relative to the line-of-sight path.

摘要： A method includes selecting a first communications network from a plurality of communications networks based on one or more aircraft state inputs. The one or more aircraft state inputs include at least one of a flight phase, a flight event, an aircraft position, an aircraft trajectory, an aircraft state, and an aircraft distance from a ground station. The method further includes transmitting data over the first communication network. The method further includes selecting a second communications network from the plurality of communications networks based on a change in the one or more aircraft state inputs.

摘要： A method for routing aircraft data link messages over a plurality of communications networks is disclosed. The method assigns at least one data link message routing service for an aircraft having a first message processing application based on prescribed criteria, the prescribed criteria comprising preferred networks of the plurality of communications networks. As a first preferred communications network becomes available, the method selects a first message route from the assigned routing service and transmits each of the data link messages on the first message route while the first message route satisfies the prescribed criteria. When the prescribed criteria changes over a plurality of flight phases of the aircraft, the method reassigns the at least one data link message route to continue data link message transmissions to and from the aircraft based on the latest prescribed criteria.
