🧠 Avionics and Support Systems (Service Module)

The avionics and support systems in the Service Module are the command and control backbone of the Gaganyaan spacecraft. They ensure mission navigation, monitoring, system coordination, and communication with ground stations.

  • Navigation & Guidance Systems: These systems help maintain the spacecraft’s orientation and trajectory using star trackers, gyroscopes, and inertial measurement units (IMUs).
  • Flight Computers: Redundant, fault-tolerant computers process mission data, execute commands, and manage automation sequences during launch, orbit, and separation.
  • Telemetry Systems: Collect and transmit real-time data (health, status, position) from onboard systems to ISRO’s mission control for constant monitoring.
  • Communication Systems: Ensure secure uplink/downlink of voice, data, and commands between the spacecraft and ground stations across all mission phases.
  • Sensor Integration: Sensors placed throughout the module detect environmental conditions, vibration, temperature, and subsystem health to enable smart fault detection.
  • Support Infrastructure: Includes power switching units, thermal controllers, and interface modules that coordinate functions between subsystems.

These avionics are rigorously tested and are designed for redundancy, accuracy, and autonomy, allowing the spacecraft to safely operate with minimal intervention.
