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.

Enhanced LDACS system having roaming agreements and associated methods

An enhanced L-band Digital Aeronautical Communications System (LDACS) may include cellular telephone ground stations, and LDACS ground stations. In addition, the enhanced LDACS may also include a plurality of LDACS airborne stations, each configured to selectively communicate with either a corresponding LDACS ground station or a corresponding cellular telephone ground station based upon an altitude of the LDACS airborne station.

Enhanced LDACS system combined with cellular telephone ground stations and associated methods

An enhanced L-band Digital Aeronautical Communications System (LDACS) may include LDACS ground stations, and LDACS airborne stations configured to communicate with the LDACS ground stations. The enhanced LDACS may also include a network controller configured to operate a given LDACS ground station and LDACS airborne station to use a primary LDACS channel and at least one supplemental LDACS channel defining an aggregated bandwidth channel, with the primary LDACS channel changing at handover from one LDACS ground station to another LDACS ground station.

Enhanced LDACS system having channel aggregation and associated methods

An Automatic Dependent Surveillance-Broadcast (ADS-B) device may include a controller and a radio frequency (RF) transmitter coupled thereto and configured to transmit flight identification data, and transmit flight position data at a coarse accuracy and a fine accuracy. The RF transmitter may be configured to operate at a frequency within the L-band Digital Aeronautical Communications System (LDACS) frequency band. For example, the controller may be configured to encapsulate the flight identification data and flight position data within a message for an LDACS.

An enhanced L-band Digital Aeronautical Communications System (LDACS) may include LDACS ground stations, and LDACS airborne stations. Each LDACS airborne station may be configured to communicate with the LDACS ground stations using at least one cellular network security feature. For example, the at least one cellular network security feature may include a Long-Term Evolution (LTE) security feature.

An enhanced L-band Digital Aeronautical Communications System (LDACS) may include LDACS ground stations, and LDACS airborne stations configured to communicate with the LDACS ground stations. The enhanced LDACS may also include a Cloud-based network controller configured to allocate LDACS resources to the LDACS ground stations and the LDACS airborne stations based upon a number of LDACS airborne stations, respective flight paths of each LDACS airborne station, a respective type of each LDACS airborne station, and historical data on communication use for each LDACS airborne station.

An enhanced L-band Digital Aeronautical Communications System (LDACS) may include LDACS ground stations, and a LDACS airborne stations configured to communicate with the LDACS ground stations. The enhanced LDACS may also include a network controller configured to operate the LDACS ground stations and LDACS airborne stations at different transmission powers to define an LDACS underlay network and an LDACS overlay network. The LDACS underlay network may have a larger cell size than the LDACS overlay network. Portions of the LDACS underlay network may be installed prior in time to portions of the LDACS overlay network.

An enhanced L-band Digital Aeronautical Communications System (LDACS) may include LDACS ground stations, and LDACS airborne stations configured to communicate with the LDACS ground stations. Each LDACS airborne station may be configured to collect respective routing metrics, and each LDACS airborne station may be selectively operable as at least one of a host and client. The enhanced LDACS may also include a peer-to-peer server configured to establish a mesh network topology from the LDACS airborne stations based upon the routing metrics, and selectively operate each LDACS airborne station as at least one of the host and client.
