Multi-Frequency Modular Software Defined Radio
MWSE space qualified SDR is a multipurpose flexible software defined radio for passive remote sensing applications: L-band radiometry, GNSS-Reflectometry and Radio Ocultations. The system can be also used as On-Board Payload Computer thanks to its Xilinx Zynq Ultrascale+ Multi Processor System on Chip.
