Thermal
Thermal Overview
The thermal system is responsible for monitoring and maintaining the temperature of all subsystems within safe limits. It ensures that each component remains within its survival temperature range when not operating, and within its operational temperature range during active use. By managing these conditions, the system protects hardware integrity and ensures reliable performance throughout the mission.Thermal vacuum testing are conducted to validate system performance under simulated space conditions.
TVT Preparations
TVT preparation involves ensuring the test chamber can meet the required conditions and securing its availability for the planned test duration. It also includes instrumenting the satellite with thermocouples at all critical points to enable accurate temperature monitoring throughout the test.
TVT Sequence
The test sequence included operation at room temperature, followed by cold and hot balance tests at flight temperatures, and thermal cycling across multiple phases. Functional testing was performed during each stage to ensure reliable operation throughout temperature transitions, before returning to room temperature conditions.
