Key highlights

Resonate Testing provides independent thermal vacuum (TVAC) testing services for small satellite programmes, supporting spacecraft developers through qualification, acceptance and reliability verification activities.

Our facility enables customers to evaluate satellite performance under the vacuum and thermal cycling conditions experienced during launch preparation, orbital operation and mission life. Testing programmes can be tailored to engineering models, qualification models, proto-flight units and flight hardware.

Working with both established space organisations and emerging NewSpace companies, Resonate supports environmental verification programmes in accordance with ECSS requirements and customer-defined specifications.

Customization

Every spacecraft programme presents unique environmental verification requirements.

Resonate can develop bespoke thermal vacuum test campaigns tailored to mission profiles, orbital conditions, temperature extremes and customer-specific qualification requirements. Test durations, thermal cycles, monitoring requirements and acceptance criteria can be configured to align with project objectives.

Integrated test programmes combining TVAC, vibration and shock testing can also be developed to streamline qualification schedules and reduce programme risk.

Flight heritage

As a Testing Service Flight Heritage can't be verified but we test for over 40 Space Customers, especially "New Space" SME's and offer TVAC, Vibration and Shock all on one site.
