EnVision  VenSpec-H   Electronics 

The VenSpec-H (Venus Spectrometer – High-resolution) instrument is one of EnVision’s key payloads. Operating in the infrared range (1.0–2.5 µm), it will measure trace gases such as SO₂ and H₂O, identifying signatures of active volcanism and chemical processes driving Venus’s dynamic atmosphere.

TRL Space leads the VenSpec-H electronics development, responsible for the DEP and MOD boards, overall project management, product assurance, and thermal analysis of all electronic units.
Our team ensures the electronics meet ESA’s ECSS standards, achieve high reliability, and perform under Venus’s demanding radiation and thermal environment. We also coordinate system integration, test philosophy, and support to the instrument prime through all design reviews.

TRL Space leads a consortium combining Czech expertise:

• SAWtronics – FPGA & PROC board design, system engineering, EGSE development
• G. L. Electronics – harness design and manufacturing, PCB assembly to ECSS standards
• AerialComm – EGSE development and functional testing for DEP and MOD boards

Together, the team provides a complete, end-to-end capability from design and analysis to qualification and testing.

The development process follows a rigorous ECSS-compliant lifecycle, from requirement consolidation and preliminary design through engineering model (EM) and qualification model (QM) manufacturing and testing. This ensures each component—from PCBs to harness assemblies—achieves the reliability required for EnVision’s deep-space environment.
