An enhanced L-band Digital Aeronautical Communications System (LDACS) includes a plurality of LDACS ground stations, each transmitting a respective carrier signal. An LDACS airborne station may be configured to communicate with the plurality of LDACS ground stations and determine position information based upon respective Doppler shifts in the plurality of carrier signals.

Enhanced LDACS that uses doppler shifts in carrier signals for positioning and navigation

An enhanced L-band Digital Aeronautical Communications System (LDACS) may include LDACS ground stations; and Alternate Positioning, Navigation and Timing (A-PNT) beacon transmitters positioned on the ground; and LDACS airborne stations. The LDACS airborne station may be configured to communicate with the LDACS ground stations, and determine A-PNT information based upon the plurality of A-PNT beacon transmitters.

Enhanced LDACS system that determines A-PNT information and associated methods

An enhanced L-band Digital Aeronautical Communications System (LDACS) may include LDACS ground stations assigned to respective different ground communication networks; and LDACS airborne stations configured to communicate with selected ones of the LDACS ground stations based upon respective roaming agreements for the different ground communication networks. In addition, the system may include a network broker configured to authorize a connection between an LDACS airborne station and an LDACS ground station based upon a corresponding roaming agreement.
