A radio communication route enables communication from an originating ground station to a destination ground station via one of multiple randomly orbiting satellites with no attitude control. The ground stations and satellites include directional antennas for receiving radio signals from and transmitting radio signals in multiple directions. The satellites store an address of a destination ground station from which an initial information signal is transmitted and antenna information identifying the satellite antenna on which the initial information signal was received. Plural satellite antennas transmit linking information identifying the satellite to the originating ground station. Data transmissions received at the originating ground station that designate a particular destination are transmitted by the originating ground station using the antenna on which the linking information was received and the satellite retransmits the data transmission using the satellite antenna identified by the stored antenna information.

A satellite communication terminal for a field environment includes: a broadband interface that creates a broadband link with a device in the field environment and that manages communication over the broadband link; a satellite antenna that creates a satellite backhaul link with a satellite in orbit; a satellite interface that manages communication over the satellite backhaul link; and a processor that controls a beam direction of the satellite antenna, performs broadband services on data exchanged with the device over the broadband link and the satellite backhaul link, and provides access to the exchanged data to the device.

A system includes a terminal and a gateway. The terminal is programmed to identify, in received data, a signature of rogue data that includes at least a device identifier and an application identifier, and to transmit, via uplink to a satellite, the identified signature to a gateway. The gateway is programmed to block downlink data, upon determining that downlink data includes the received signature, and to broadcast the received signature to a second gateway.

A process for improving network performance in systems that utilize secure domain name system (DNS) schemes. Encrypted DNS requests from devices in a local area network (LAN), such as a home or office, are submitted to a local proxy which stores cached DNS records. The proxy decrypts or examines at least a portion of the DNS request in order search for a matching record in its storage. Matching records are retrieved, encrypted, and supplied to the requesting device to satisfy the DNS request. If the proxy does not contain a matching record, the DNS query is encrypted and submitted to an external DNS server for resolution. The matching record can optionally be saved by the proxy prior to being supplied to the requesting device.

In an exemplary embodiment, a phased array antenna comprises multiple subcircuits in communication with multiple radiating elements. The radio frequency signals are independently adjusted for both polarization control and beam steering. In a receive embodiment, multiple RF signals of various polarizations are received and combined into at least one receive beam output. In a transmit embodiment, at least one transmit beam input is divided and transmitted through multiple radiating elements, with the transmitted beams having various polarizations. In an exemplary embodiment, the phased array antenna provides multi-beam formation over multiple operating frequency bands. The wideband nature of the active components allows for operation over multiple frequency bands simultaneously.

A method and system for providing GTP acceleration for secure cellular backhaul over satellite (CBoS). A satellite terminal receives request from a first entity to establish a security association with a second entity, and establishes a first secure tunnel to a gateway. A second secure tunnel is then established between the gateway and the second entity based on a certificate belonging to the first entity. A third secure tunnel is established between the satellite terminal and the first entity based on a certificate belonging to the second entity. The contents of encrypted traffic between the first entity and the second entity are examined so that GTP acceleration may be applied to eligible traffic transmitted over the first secure tunnel.

A satellite modem, a GPS device, and a method are provided. The satellite modem requests current location information from a GPS device and waits no more than a preconfigured amount of time to receive the current location information. When the satellite modem receives the current location information, the satellite modem determines whether the current location information indicates a location in which the satellite modem is authorized to operate. When the satellite modem determines that the current location information indicates a location in which the satellite modem is not authorized to operate, the satellite modem performs at least one action from a group of actions including preventing the satellite modem from operating normally, permitting the satellite modem to operate with a reduced functionality, and transmitting a message to a network management center indicating that the satellite modem is not located at an authorized location.
