Space communications architecture concepts, comprising the elements of the system, the interactions among them, and the principles that govern their development, are essential factors in developing National Aeronautics and Space Administration (NASA) future exploration and science missions. Accordingly, vital architectural attributes encompass flexibility, the extensibility to insert future capabilities,...
The National Aeronautics and Space Administration (NASA) / Harris Ka-Band Software Defined Radio (SDR) is the first, fully reprogrammable space-qualified SDR operating in the Ka-Band frequency range. Providing exceptionally higher data communication rates than previously possible, this SDR offers in-orbit reconfiguration, multi-waveform operation, and fast deployment due to its highly modular hardware...
The design, fabrication and RF performance of the output traveling-wave tube amplifier (TWTA) for a space based Ka-band software defined radio (SDR) is presented. The TWTA, the SDR and the supporting avionics are integrated to forms a testbed, which is currently located on an exterior truss of the International Space Station (ISS). The SDR in the testbed communicates at Ka-band frequencies through...
The NASA SCaN Test Bed flight experiment payload aboard ISS will enable experimenters the unique opportunity to investigate SDRs, navigation, and networking in the space environment. Comprised of three SDRs from industry partners, CoNNeCT allows experimenters to develop and verify new waveforms compliant with the STRS SDR architecture standard, using verified ground systems and then have those waveforms...
National Aeronautics and Space Administration (NASA) is developing an on-orbit, adaptable, Software Defined Radios (SDR)/Space Telecommunications Radio System (STRS)-based testbed facility to conduct a suite of experiments to advance technologies, reduce risk, and enable future mission capabilities. The flight system, referred to as the “SCAN Testbed” will be launched on an HTV-3 no earlier than May...
