Abstract: A double data rate (DDR) RF digitization module for a software defined radio (SDR) is disclosed. In embodiments, the DDR RF digitization module includes a printed circuit board (PCB) terminating in a DDR memory bus interface comprising a plurality of input/output (I/O) connectors insertable into a DDR slot of an SDR motherboard. The RF digitization module is connectable to an RF front end of the SDR via receiver-side (Rx) and transmitter-side (Tx) RF connectors. The RF digitization module includes DDR analog-digital converters (ADC) and digital-analog converters (DAC) mounted to the PCB and in communication with the RF front end and the DDR memory bus. The DDR ADCs provide high speed digital sampling of inbound RF signals for the signal processors via the DDR memory bus, and the DDR DACs provide high speed generation of transmittable analog RF signals based on digital spectrum data generated by the signal processors.

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: 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 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.
