Multi-band software defined radio for spaceborne communications, navigation, radio science, and sensors

FPGA-Based Software-Defined Radio and Its Real-Time Implementation Using NI-USRP

“…This will impact heavily on the radio frequency (RF) segments of the terminal and it is this area which is arguably the main technology limitation on software-defined radio implementation at present [15] (although processor power consumption and cost are still both major issues for SDR).…”

In-flight performance of the Van Allen Probes RF telecommunications system

“…The DSP slice supplies the central control of the radio (including bit rate selection, encoding, and included hardware command decoder), and provides the control, command and telemetry interfaces to the spacecraft. This compact design provides state-of-the-art mass (1.8 kg with 100-mil chassis) and power (o9 W full duplex) for the offered capability [9][10][11][12][13][14].…”

Digital signal processing architecture design for gate array based software defined radios

“…Most importantly, the 7 ASICs were not an option due to project time and funding. 8 The Frontier Radio hardware design is divided into several slices [5]. The DSP Slice holds the FPGA, analog-to-digital converters for the receive signal, and digital-to-analog converters for generation of the modulation waveforms.…”

“…In 2006 JHU/APL was funded by NASA to take the New Horizons low SWaP radio design and incorporate Ka-Band transmission capability to create a new radio for future deep-space missions in a similar class to New Horizons [5].…”

“…4 Comet Nucleus Tour (CONTOUR) was a Discovery class NASA mission to study comet structure. 5 A New Frontiers class NASA mission to observe the Pluto system and other Kuiper Belt objects.…”
