The radio frequency telecommunications system for the NASA Europa clipper mission The NASA Europa Clipper mission, a partnership between the California Institute of Technology Jet Propulsion Laboratory (JPL) and the Johns Hopkins University Applied Physics Laboratory (APL), is currently in Phase B and scheduled for launch in 2022. A Jupiter orbiter, it will perform repeated flybys of the moon, Europa, to assess the icy moon’s structure and habitability. The spacecraft’s dual X/Ka-band radio frequency telecommunications subsystem has five primary functions: Provide spacecraft command capability ...

From prototype technology to flight: Infusing the Frontier Radio into space missions New technologies are constantly being developed at many space-related institutions. A significant challenge is to not only propose and develop these new technologies, but to infuse them into real space missions. The Johns Hopkins University Applied Physics Laboratory (JHU/APL) has a successful history of infusing such new technologies into NASA flight programs, including non-coherent navigation in the CONTOUR mission (launched 2002), a circularly-polarized phased-array antenna on the MESSENGER mission (2004), and a low-power ...

Enabling coherent Ka-band downlink with a software-defined radio The migration to Ka-band for science downlink on deep space missions increases data rates significantly, but also presents new challenges to radio and RF system designers. One challenge is to maintain low carrier phase noise on a coherent downlink. Thermal noise on the X-band uplink that is within the bandwidth of the carrier recovery process modulates the phase of the coherent downlink. For missions that use X-band for command uplink and Ka-band for science downlink, such as the NASA Solar Probe Plus mission, the ratio of d ...

The Frontier software-defined radio for the solar probe plus mission The latest adaptation of the Frontier Radio, an X/Ka-band deep space implementation, has been transitioned into a finished product for Solar Probe Plus (SPP) and future missions. Leveraging the technology readiness level (TRL) 9 software-defined radio (SDR) platform successfully flown on the Van Allen Probes (VAP) mission, the Frontier Radio now brings a low-power, low-mass, yet highly radiation-tolerant and robust SDR to deep space applications. This implementation brings with it a suite of enhanced capabilities and improve ...
