TX (2200 to 2290 MHz) and RX (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.
The selection of modulation is critical for closing the link between a satellite and its ground station. The SRS-4’s use of 8PSK (8 Phase-Shift Keying) offers the highest spectral efficiency for its maximum rate, while BPSK (Binary Phase-Shift Keying) provides the most robust performance for weak signals, down to an impressive sensitivity of . When combined with CCSDS-recommended channel coding, the link becomes highly resilient to noise and interference, ensuring data integrity over long distances.
Seamlessly routes Internet Protocol data directly to advanced scientific or technology-demonstration payloads onboard. srs-4 satlab
The is a high-performance, full-duplex S-band transceiver engineered specifically for micro- and nano-satellites. Developed by Satlab A/S (based in Aalborg, Denmark), this software-defined radio (SDR) provides a reliable, flight-proven solution for both Telemetry, Tracking, and Command (TT&C) operations and high-speed payload data transmission.
: Efficient operation with a typical RX-only consumption of 1.5 W and a combined RX+TX consumption of 10.8 W at maximum output. Advanced Features for Satellite Missions
HYPSO-2 is a 6U CubeSat designed for hyperspectral imaging of ocean environments. It features a software-defined communication payload and needs to downlink vast quantities of image data back to Earth. The mission will be equipped with a . TX (2200 to 2290 MHz) and RX (2025 to 2110 MHz)
Compact PC/104 form factor (93.0 x 87.2 x 18.0 mm).
In a modern configuration, the "SatLab" component typically serves as the RF front-end and digitizer. The key advantage here is .

To guarantee smooth interoperability with commercial ground networks (such as Leaf Space or KSAT) alongside sovereign academic networks, the Satlab SRS-4 adheres strictly to standard global frameworks:
The core of the Satlab SRS-4 centers on its agile SDR architecture. This hardware configuration allows satellite operators to configure transmission parameters dynamically while in orbit, reducing mission risk and adjusting to changing ground networks.
: The device is fully on-orbit software upgradable, allowing operators to adjust frequencies, bit rates, and framing while in flight. Power Management : It features adjustable output power up to
: The device remains resilient against long-term mission scope changes. Its underlying field-programmable architecture remains fully on-orbit software upgradable via Satlab's specialized firmware resource architecture . Mission Integration and Lead Times
The SRS-4 SatLab offers numerous benefits to users, including:
