TOTEM Software Defined Radio (SDR)

The Alén Space TOTEM Software Defined Radio (SDR) is a flight-proven software defined radio system suitable for communication with nanosatellites. TOTEM operates in commonly-used nanosatellite frequency bands using Xilinx's Zynq-7000 SoC with an embedded Linux and programmable logic. It also includes a wide frequency range transceiver and can be reconfigured in-orbit.

Main Features:

• High-performance System-On-Chip (SoC) - Xilinx Zynq-7000 series
• Wide frequency range RF transceiver (AD9364)
• Full duplex communication
• FSI-connector based interface
• Option to combine in the same payload several applications (SDR, ADS-B, AIS, IoT, and SIGINT) with different frequency bands
• SDR transceiver across several frequency bands: UHF, VHF, S-band and L-band
• Processing capabilities for X-band, Ka-band and Ku-band

Software highlights:

• Safe in-orbit updates
• TOTEM TMTC based on ECSS PUS (ESA)
• Compatibility with radio applications such as GNUradio and SoapySDR

OPTIONAL EQUIPMENT

This bundle can also include an Electrical Ground Support Equipment (EGSE) to help developers with programming, debugging and testing TOTEM’s software. This equipment allows direct communication to the TOTEM, integrating standard physical interfaces and connectors to plug commercial adapters, facilitating tasks and speeding up the developing stage.
