An aircraft system comprises a first and second transceiver each configured to transmit and receive radio signals in respective first millimeter wave (mmW) frequency band and second mmW frequency band; and a processing unit configured to provide the data signals to the first and second transceivers for transmission and to receive demodulated signals from the first and second transceivers. The processing unit is further configured to output signals to alter the orientation of the first antenna to establish a first point-to-point connection with a first aircraft and to output signals to alter the orientation of the second antenna to establish a second point-to-point connection with a second aircraft; the first point-to-point connection and the second point-to-point connection forming part of a point-to-point aircraft relay ring network communicatively coupling a plurality of aircraft in a shared flight route area to each other.

System for characterizing weather and modifying operation of at least one transceiver

In an embodiment, a system includes base stations and a server. Each base station has a respective fixed position, and is configured to broadcast information that a mobile station can use to determine a position of the mobile station. And the server is configured to communicate with the base stations and to track a position of a mobile station. An example of such a system is an Aeronautical Mobile Airport Communications System (AeroMACS), which includes base stations that are located in respective fixed, known positions within and around an airport, and at least one server that communicates with the base stations and tracks the positions of moveable stations within and around the airport. The base stations can provide information that allows both GNSS-enabled and non-GNSS-enabled mobile stations to determine their positions without adding significant cost or complexity to the AeroMACS.
