Abstract: A radio device includes a hardware antenna, an analog-to-digital converter, and a processing circuit. The hardware antenna is configured to receive an analog signal corresponding to a radio frequency waveform. The analog-to-digital converter is configured to convert the analog signal to a digital signal corresponding to the radio frequency waveform. The processing circuit is configured to provide the digital signal corresponding to the radio frequency waveform to a first application; execute the first application using the digital signal to generate a first output instruction; execute an application programming interface to convert the first output instruction to a second output instruction; and execute the second output instruction.

Abstract: A system can include one or more processors and computer-readable instructions that when executed by the one or more processors, cause the one or more processors to provide a first test signal to an electronic device, monitor at least one parameter of the electronic device during a time period subsequent to the test signal being provided to the electronic device, determine, based on the at least one parameter, a detected response of the electronic device to the first test signal, determine, using a response model, an expected response of the electronic device to the first test signal, and provide a second test signal based on the detected response and the expected response to the electronic device. The system can include a communications circuit that provides the test signal and receives at least some feedback indicating the parameters, and sensors that receive at least some feedback indicating the parameters.

Abstract: Embodiments of the inventive concepts disclosed herein are directed to systems and methods for operating in multiple transmissions modes for satellite communications. A controller of a radio device may set a transmission mode of a single transceiver chain to a first communications protocol. The single transceiver chain may communicate with a satellite antenna using the first communications protocol. The controller may modify the transmission mode of the single transceiver chain from the first communications protocol to a second communications protocol. The controller may maintain synchronization for the first communications protocol. The single transceiver chain may transmit a first signal to the satellite using the second communications protocol, responsive to modifying the transmission mode. The single transceiver chain may simultaneously receive a second signal using the first communications protocol and the synchronization, and a third signal using the second communications protocol.

Abstract: A system and related method for minimizing co-channel interference in air-to-ground single-frequency networking includes aircraft-based directional and omnidirectional antenna arrays for transmitting to single frequency networks (SFN) (e.g., LTE, HSPA) and their cell sites. The directional array may encompass several cell sites to take advantage of C-RAN architectures. The system may default to the directional array to establish or re-establish network access, identifying accessible networks and sites and monitoring corresponding synchronization cell counts. The system may minimize co-channel interference with terrestrial network users by switching to the directional array if the count of accessible cell sites or networks becomes high enough, or due to additional factors (e.g., climbing above a threshold altitude). Similarly, the system may switch to the omnidirectional array if the cell count drops below a threshold level.

Abstract: A computer defined radio includes a Mobile User Objective System (MUOS) terminal configured to instantiate two or more virtual terminals. Each of the two or more virtual terminals provides all of the functionality of a MUOS terminal with satellite communication through a single antenna. Each of the two or more virtual terminals may join a separate group as defined by MUOS specifications, and give the single MUOS terminal access to the disparate groups. Each of the two or more virtual terminals is configured to operate at a different bitrate such that the total power consumption of the MUOS terminal is less than the same number of physical terminals operating separately.

Abstract: A signal extender and method for extending signals of a satellite is disclosed. The apparatus includes a terminal device interface, an antenna interface and a controller in communication with the terminal device interface and the antenna interface. The terminal device interface is configured for communicating with at least one terminal device. The antenna interface is configured for communicating with an antenna to facilitate communication with the satellite. Upon receiving a downlink signal from the satellite via the antenna interface, the controller processes the downlink signal to identify an intended terminal device among the at least one terminal device and transmits the downlink signal to the intended terminal device via the terminal device interface, and upon receiving an uplink signal from a particular terminal device via the terminal device interface, the controller transmits the uplink signal to the satellite via the antenna interface.

Abstract: A method and related system is disclosed for emulation of a Mobile User Objective System (MUOS) ground base station. A Software Defined Radio (SDR) based architecture with interpreted scripting languages interfaces with open source software running in an embedded environment to emulate entire MUOS ground transportation segment. The ground base station emulation resides on a server remote from the MUOS enabled terminals or embedded within MUOS enabled terminals. It is transparent to the MUOS enabled terminal whether the terminal is in communication with the emulation of or the actual MUOS ground base station.
