Highly sensitive, achieving -122 dBm (
Seamlessly routes Internet Protocol data directly to advanced scientific or technology-demonstration payloads onboard.
For ground testing, Satlab provides GNU Radio example flowgraphs, enabling engineers to validate radio interfaces before launch. The device's ability to handle both simultaneously makes it a flexible choice for modern satellite missions requiring high-speed data transfer and complex networking.
This choice by NTNU highlights the SRS-4’s suitability for a modern, complex satellite mission, where high downlink speeds and robust performance are non-negotiable. Furthermore, the European Space Agency (ESA) is using the SRS-4 as a foundation for its project, underscoring the unit's adaptability for future satellite-to-satellite communication networks. srs-4 satlab
The transceiver operates as an intelligent edge router within the spacecraft's internal avionics architecture. It supports:
: To safeguard against unauthorized command injection or eavesdropping, the SRS-4 implements AES-256-GCM link-layer encryption and authentication . Security keys are validated at the radio layer, mitigating risks before bad packets ever reach internal sub-systems. Mission Applications
The SRS-4 excels in scenarios requiring reliable, high-throughput links from orbit: Highly sensitive, achieving -122 dBm ( Seamlessly routes
To ensure seamless interoperability with international ground networks, the SRS-4 adheres strictly to . It features runtime-configurable convolutional and Reed-Solomon Forward Error Correction (FEC), mitigating space-link attenuation and preventing data corruption across noisy atmospheric bounds. 3. Versatile Software Interfaces & Routing
Enter the , a full-duplex, high-speed S-band transceiver that has quickly established itself as a key player in the small satellite industry. Designed by Satlab A/S specifically for micro- and nano-satellites, the SRS-4 combines a compact form factor with powerful RF performance, robust data security, and extensive flight heritage.
Furthermore, the SATLAB facilitates . When a software patch is uploaded to an active satellite, the same patch is first executed on the SRS-4 SATLAB. If the lab satellite enters safe mode, the ground team knows not to send the patch to the orbital asset. This choice by NTNU highlights the SRS-4’s suitability

The SRS-4 Satlab system offers several benefits and advantages, including:
Unlike half-duplex systems that must switch between transmitting and receiving, the SRS-4 allows simultaneous transmission and reception (full-duplex) satsearch.
