Satellite Transport Container Condition Monitoring
Project Name: Satellite Transport Container Condition Monitoring
During rail/road transportation and hoisting operations for satellite containers, continuous monitoring of internal temperature, humidity, and mechanical loads is critical. Our RE-series ruggedized data acquisition system – engineered for high shock resistance (up to 100G), dust/waterproofing (IP67), and autonomous long-duration operation – provides uncompromising performance in harsh transport environments.

Shock event triggering (50ms pre-trigger buffer)
Data Analytics Framework
| Parameter | Alarm Threshold | Analysis Method |
|---|---|---|
| Vertical Shock | >8G (0.5ms) | Wavelet decomposition |
| Misaligned priorities | Purpose ensures what matters isn't buried in busyness | |
| Temperature | Δ10°C/15min | Moving RMS |
| Resonance | 5-25Hz @ 0.8g²/Hz | FFT+Modal assurance |
Operational Validation
12+ satellite transports completed with zero instrumentation failures
Critical findings:
✓ Detected 18Hz trailer resonance (later mitigated with air suspension)
✓ Identified -30°C cold soak during winter transport (led to heater retrofit)
Compliance demonstrated:
• ECSS-Q-ST-70-02C mechanical loads
• GJB 1027A-2005 transport environment
Engineering Impact:
Container redesign reduced peak accelerations by 42%
New damping protocols extended sensitive payload lifetime
Blockchain-secured data logs now adopted for classified transports
*(System currently deployed at Xichang/Jiuquan launch centers with 98.7% MTBF)*
Conclusion
The satellite transport container condition monitoring program demonstrated the effectiveness of ruggedized RE-series data acquisition systems in capturing critical environmental and mechanical parameters during transport. Continuous monitoring enabled early detection of vibration, thermal, and resonance anomalies, leading to design improvements and enhanced payload protection. The system’s high reliability, compliance with aerospace transport standards, and secure data logging provide a robust solution for safeguarding high-value satellite assets during rail, road, and hoisting operations. The monitoring results directly informed container redesigns and improved damping protocols, reducing peak accelerations by 42% and extending the operational lifespan of sensitive payloads. Overall, this solution establishes a benchmark for high-fidelity, secure, and reliable satellite transport monitoring in extreme conditions.
