Understand everything about Varuna Mission in under five minutes!
Mission Objectives
Varuna is an in-orbit technology demonstrator intended to help achieve flight worthiness of our subsystems for all future missions. On completion of the mission, we will have Technology Readiness Level 9 (highest level) for the subsystems.
- Study the deployable Reflectarray Antenna
- Test all the SAR Electronics
- Test the Electronic Power Conditioner (EPC)
- Test pre-driver stage of high efficiency solid-state power amplifier and other components in Radar Transmit receive chain

Varuna Hardware & Subsystems

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.

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.

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.

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.

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.

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.

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

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