A method and system facilitate communication between a constellation of satellites and a mobile platform-mounted mobile communicator. The method and system may include the use of a first antenna suited for operation using a first frequency band in a first geographic region and a second antenna suited for operation using either the first or a second frequency band in a second geographic region. The method and system may use a controller to determine which antenna to activate based on one or more of a geographic indicator or a signal indicator. The system used by the method to facilitate the communication may have one or more enclosures over the antennas and controller for mounting to a mobile platform.

Mobile communicator and method of communicating data with a mobile communicator

A method of communicating with satellites in a low-earth orbit (LEO) constellation includes determining, by a controller of a mobile communicator mounted on a mobile platform, one or more conditions corresponding to a plurality of spatial channels associated with multiple satellites in the LEO constellation. The method also includes allocating, based on the one or more conditions, each subset of a plurality of subsets of antenna resources of a phased array antenna to a respective different satellite included in the multiple satellites in the LEO constellation, where the antenna resources of the phased array antenna are communicatively connected to plurality of transceivers via a bus. The method also includes commanding the plurality of transceivers to establish simultaneous communicative connections to the different satellites via the allocated subsets of antenna resources.

LEO constellation satellite terminal

A method of communicating with satellites in a low-earth orbit (LEO) constellation includes determining, by a controller of a mobile communicator mounted on a mobile platform, one or more conditions corresponding to a plurality of spatial channels associated with multiple satellites in the LEO constellation. The method also includes allocating, based on the one or more conditions, each subset of a plurality of subsets of antenna resources of a phased array antenna to a respective different satellite included in the multiple satellites in the LEO constellation, where allocating each subset includes allocating a particular antenna resource to two or more subsets of the plurality of subsets of the phased array antenna. The method also includes commanding one or more transceivers to establish simultaneous communicative connections to the different satellites via the allocated subsets of antenna resources.

Antennas used aboard vehicles to communicate with satellites or ground stations may have complex antenna patterns, which may vary as the vehicle moves throughout a given coverage area. Techniques are disclosed for dynamically adjusting the instantaneous power fed to an antenna system to ensure that the antenna transmits at the regulatory or coordinated effective isotropic radiated power (EIRP) spectral limit. The antenna may transmit, in accordance with vehicle location and attitude, steerable beam patterns at different scan and skew angle combinations, causing variations in antenna gain and fluctuations in the transmitted EIRP. Using on-board navigational data, an antenna gain and ESD limit may be calculated for a particular scan and skew angle, which may be used to adjust power fed to the antenna such that the antenna transmits substantially at maximum allowable EIRP as the steerable beam pattern is adjusted.

Dynamic effective radiated power (ERP) adjustment

A method of communicating with multiple satellites includes allocating, based on one or more conditions corresponding to a plurality of spatial channels associated with multiple satellites, each subset of a plurality of subsets of antenna resources of a phased array antenna to a respective different satellite included in the multiple satellites. The method also includes commanding one or more transceivers to establish simultaneous communicative connections to the different satellites via the allocated subsets of antenna resources, and re-allocating, based on a detected change to at least one of the one or more conditions, at least one antenna resource to a respective another different satellite. The method also includes commanding the one or more transceivers to maintain the simultaneous communicative connections to the different satellites using the re-allocated at least one antenna resource.

Multiple antenna system and method for mobile platforms

Systems and methods for detecting and reducing signal interference affecting wireless communication with a mobile vehicle includes generating an interference signature based on a correlation multiple signal-quality characteristics of a desired target-signal that is received at an antenna assembly attached to the mobile vehicle, and adjusting the orientation of the antenna assembly based on a change or degradation in the interference signature to thereby improve wireless communication with the vehicle.

Systems and methods for detecting satellite-based communication interference

Techniques, systems, devices, and methods for utilizing a mobile communicator for communicating with multiple satellites, e.g., simultaneously over an interval of time, are disclosed. The mobile communicator is disposed on a vehicle, and the multiple satellites may be disposed in different satellite constellations operating in different orbits. The mobile communicator establishes multiple communication links to the multiple satellites by utilizing only the set of antenna resources provided by a single antenna platform or array. Subsets of the antenna resources are dynamically apportioned and adapted, e.g., while the vehicle travels, to establish and maintain different communication links to different satellites via different spatial channels and their respective air interfaces to thereby maintain optimal satellite communicative connectivity. On-board connectivity services for personal electronic devices and/or other on-board applications may be supported by the disclosed techniques.

Antennas used aboard aircraft to communicate with satellites or ground stations may have complex antenna patterns, which may vary as the aircraft moves throughout a given coverage area. Techniques are disclosed for dynamically adjusting the instantaneous power fed to an antenna system to ensure that the antenna transmits at the regulatory or coordinated effective isotropic radiated power (EIRP) spectral limit. The antenna may transmit, in accordance with aircraft location and attitude, steerable beam patterns at different scan and skew angle combinations, causing variations in antenna gain and fluctuations in the transmitted EIRP. Using on-board navigational data, an antenna gain and ESD limit may be calculated for a particular scan and skew angle, which may be used to adjust power fed to the antenna such that the antenna transmits substantially at maximum allowable EIRP as the steerable beam pattern is adjusted.

A radome having localized areas of reduced radio signal attenuation includes a body having a first portion and a second portion. The first portion has a reduced radio signal attenuation property in a transmit band and a second portion has a reduced radio signal attenuation property in a reception band.
