Multi-channel space radio covers 300MHz to 6GHz

Cesium SDR-1001 space radio

Call SDR-1001 (cover removed) right) and tested to NASA GEVS standards, it has four transmit and four receive channels, adjustable from 300MHz to 6GHz. The bandwidth is 100MHz per channel.

It is based on the FPGA “with 70% of the resources available for custom design”, according to the company.

By default, it comes with a preloaded CSMA network reference modem (multiple access media) with SpaceWire and Ethernet connectivity.

“When two SDRs establish a connection, data packets from Ethernet, SpaceWire or a serial port are redirected through the connection,” the company said. “Cesium also develops turnkey signal support for DVB-S2, DVB-S2X and CCSDS with data rates up to 500Mbit / s.”

The connected FPGA development kit allows custom FPGA waveforms to be built and implemented, with the basic BSP firmware (on-board support package) providing an API for RF front-end management and data management and enabling access to IQ main bar data. The kit also includes support and training.

The redundancy and interrupt logic is integrated to ensure the resilience of radiation events, with on-board telemetry providing information on system health and power management.

Its robustness and programmability make it suitable for low-to-ground missions lasting five to seven years, Cesium said.

Although available as a stand-alone module, the device can be used with other products in the Cesium module range, including integrated L-band, S-band, X-band, Ku-Band and Ka-Band connectivity and phased array units.

The company is headquartered in Austin, Texas, and has offices in Broomfield, Colorado.
