Srs-4 Satlab [COMPLETE]
Built on a polyimide PCB for thermal performance, the SRS-4 is housed in a milled aluminum enclosure
standard modulation techniques used in satellite communication Satlab SRS-4 Datasheet Revision 1.2
: 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
The transceiver accommodates multiple bandwidth profiles. It supports BPSK, QPSK, and 8PSK for downlink transmissions, and BPSK/QPSK for uplinks, maximizing spectral efficiency.
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 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 .
