Varuna’s Journey To Space-Readiness

Varuna has undergone several rigorous tests to ensure it’s mission-ready and capable of meeting the demanding challenges of space.

Deployment Tests

We've successfully tested the deployment mechanisms for our antenna, a critical step to ensure they function correctly once in orbit. It was like watching a sci-fi movie, only real – and with more coffee.

Revealed soon...

Vibration Test

In the vibration test, our hardware endured nearly two minutes of rigorous shaking, simulating the jolts of space travel. It passed with flying colors, proving its resilience and readiness for the challenges of the cosmos.

Revealed soon...

Active Thermal Test

Our electronic power conditioner underwent active thermal testing to simulate the operational environment in space, ensuring it can handle the intense conditions.

Revealed soon...

Thermo-Vacuum Test

We subjected our components to the space environment in a thermo-vacuum chamber, exposing them to the extreme temperatures and vacuum of space to ensure they can perform flawlessly.

Revealed soon...

Antenna CATF Test

Our indigenously developed reflect array antenna was tested in Compact Antenna Test Facility to check the gain, beamwidth and other antenna specific parameters.

Revealed soon...

Sine-Burst Test

Sine Burst (SB) Testing is used for strength testing of space hardware. Our hardware was subjected to bursts of strong vibration with increasing vibration levels and frequency of vibration.

Revealed soon...

Shock Test

Our hardware survived 1500g of shock which it will endure in space during deployment of primary payload on launch vehicle.

Revealed soon...

EMI/EMC Test

We subjected our electronics with electromagnetic radiation to check performance of the satellite in case of electromagnetic interference.
