Thermal Vacuum Testing (TVAC)

AQMAAR offers comprehensive Thermal Vacuum (TVAC) testing to validate satellite survivability in simulated space environments. This service combines high-vacuum conditions with extreme thermal cycling to verify the thermal control subsystem (TCS) design and overall system workmanship.

Key Capabilities:

• Thermal Balance: Verifies the satellite's thermal model against actual performance in steady-state conditions.
• Thermal Cycling: Subjects the hardware to alternating hot and cold soaks to stress-test materials and solder joints.
• Bake-Out: Removes volatile contaminants (outgassing) prior to sensitive operations.
• Functional Testing: Complete system operation monitoring while under vacuum conditions
