The mission marks a major step for India’s semiconductor self-reliance as a domestically built space-grade chip powers onboard spacecraft systems.
PierSight has achieved a significant milestone by integrating an indigenous semiconductor developed by Semi-Conductor Laboratory (SCL) into the onboard electronics of its Varuna 2.0 spacecraft. The collaboration highlights growing synergy between India’s private space startups and government-backed semiconductor capabilities.
SCL, operating under the Ministry of Electronics and Information Technology, remains India’s only semiconductor facility dedicated to space and defence applications. The deployment marks one of the first instances of a private Indian space company flying an SCL-manufactured chip in active spacecraft electronics, representing an important step toward strengthening domestic technology self-reliance.
The integrated chip combines two essential functions within a single integrated circuit — a watchdog timer and a voltage supervisor. Installed in the spacecraft’s onboard computer (OBC) and payload controller, the device continuously monitors power supply stability and system voltages. If voltage levels drift beyond safe operating limits, the chip automatically triggers a reset to safeguard critical electronics.
Beyond power monitoring, the watchdog functionality supervises system logic states. In case of system freezes, incorrect operating modes, or processing errors, the chip initiates a reset sequence, enabling the spacecraft to recover autonomously and continue operations without disruption.
The Varuna 2.0 onboard computer equipped with the SCL chip has already passed thermal qualification testing, confirming reliable performance under simulated space conditions. According to PierSight, the component meets space-grade screening standards while matching the performance of imported alternatives at a significantly lower cost.
The successful deployment establishes valuable “space heritage” for the indigenous chip, encouraging wider adoption among Indian space startups and potentially attracting international customers. It also reduces dependence on foreign semiconductor components while reinforcing confidence in locally designed technologies.
The initiative aligns with national programs such as India Semiconductor Mission, Make in India, and Atmanirbhar Bharat, demonstrating India’s progress toward building a resilient, self-sufficient semiconductor and space technology ecosystem.
