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 ...

Advancements in hardware design for the frontier radio used for the solar probe plus mission The Frontier Radio for the Solar Probe Plus mission offers a host of hardware design and manufacturing improvements. These improvements build on the technology readiness level (TRL)-9 radio platform that was flown on the Van Allen Probes mission in a duplexed S-band configuration and several development tasks funded by NASA Headquarters. Prior RF slice designs consisted of two separate circuit boards: one for lower frequencies and one for high-frequencies; advances in technology enabled the use of a high-frequency multilayer ...

Development of a flight qualified ka-band multi-chip module for the solar probe plus mission The Johns Hopkins University Applied Physics Lab (JHU/APL) has developed a flight qualified, hermetically sealed, I/Q modulator Ka-band Multi-chip Module (MCM). Prototypes of this device have been developed over the years, but Solar Probe Plus (SPP) will be the first mission to use a flight qualified version of the MCM. This MCM enables a first for a deep-space mission: primary science data downlink with simultaneous data and navigation over Ka-band. SPP will also be the first JHU/APL mission to use Ka-band for downlink. The ...

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 ...
