Srs-4 Satlab //free\\
The is a flight-proven (TRL 9) full-duplex S-band transceiver designed for micro- and nano-satellites, with over 100 units delivered for orbital missions since 2021. Key Features & Capabilities
: Transmits at 2200 to 2290 MHz and receives at 2025 to 2110 MHz .
Historically, if a demodulator failed, you had to buy a new one from the vendor. In an SDR-based SRS, the "demodulator" is just a file of code. If you need to support a new modulation scheme (like a newer DVB-S2X standard), you simply update the software. No truck roll required.
To address these challenges, researchers and developers are exploring new technologies and techniques, including: srs-4 satlab
The is a high-speed, full-duplex S-band transceiver designed specifically for telemetry, tracking, and control (TT&C) as well as high-speed data transfer on micro- and nano-satellites. It is a Software Defined Radio (SDR) platform that has achieved a Technology Readiness Level ( TRL 9 ) with extensive flight heritage since 2021. Key Features
The SRS-4 is primarily used in missions where high-speed downlinks are required for imagery, scientific data, or complex telemetry. It is often integrated into CubeSat platforms provided by manufacturers like NanoAvionics , where it is listed at a price point of approximately €20,390 per unit .
Satlab provides deep developer support, offering client libraries in C and Python (wrapping the CSP protocol) along with open-source reference implementations and example code. Uncompromising Security and Maintainability The is a flight-proven (TRL 9) full-duplex S-band
, providing enough "pipe" to send high-resolution images or complex scientific data back to Earth. Sensitivity : With a sensitivity of
It utilizes 2200 to 2290 MHz for transmitting (downlink) and 2025 to 2110 MHz for receiving (uplink).
. This means it can send back high-resolution photos of Earth or complex climate data in seconds rather than hours. The Power Balance In an SDR-based SRS, the "demodulator" is just
: Satlab built this radio to be "flight-proven." In our story, when the satellite emerges from the dark side of the Earth and hits the first bit of sunlight, the SRS-4 boots up instantly. It catches the signal from a ground station with a sensitivity of —essentially hearing a whisper from across a continent. The Success
The "SRS-4 / SatLab" type configuration is a prime example of the . It represents a move away from heavy, expensive, analog-centric infrastructure toward flexible, software-defined, cloud-native operations. The value proposition is no longer about who has the biggest dish, but who has the most agile software stack to process the data.
The system runs both CubeSat Space Protocol (CSP) and standard IP routing concurrently over its space link.
