Thermal Vacuum Chamber Test Solution for Satellite Validation by WinSoft

Environmental testing of spacecraft and satellite subsystems in a thermal vacuum chamber is typically the final but most complex and expensive test conducted. Engineers needing data acquisition and control functionality for this final test require an accurate, flexible, and reliable solution. This can be even more challenging when working in large facilities supporting multiple, distributed thermal vacuum atmosphere chamber (TVAC) systems for which network connectivity and stand-alone operation or remote-control options are important. Using a complete TVAC test solution offers:


  • Reduced development time using out-of-the-box hardware
  • Proven reliability through a test solution used for more than 15 functioning satellites
  • Trusted IP package for thermal, electrical, structure, and pressure
  • High-channel-count, modular, and scalable software for DAQ, control, analysis, reporting, and display

Solution Overview

  • Ability to work with NI PXI Chassis through a variety of modules including NI SCXI
  • Client-server architecture with a dedicated test configuration interface
  • Real-time, remote monitoring over the internet (VPN) of thousands of sensors and 10,000 to 15,000 telemetry signals
  • Over 200 closed-loop proportional, integral, and derivative (PID) controls (editable and auto-tuned)
  • Hierarchical-level password-protected graphical user interface for local and remote system configuration, operation, and maintenance
