ISRO’s Next-Gen Satellite Brain: A Game-Changer in Space Technology

The Indian Space Research Organisation (ISRO) is revolutionizing satellite technology with its new Integrated Avionics Package (IAP), a compact system designed to streamline satellite functions. This innovation is crucial for competitive exams like SSC, PSC, NID, NIFT, and FDDI, where current affairs on space technology are frequently tested.

ISRO’s Integrated Avionics Package (IAP): A Detailed Look
Scientists at ISRO’s UR Rao Satellite Centre (URSC) in Bengaluru are working on a groundbreaking all-in-one avionics system that consolidates multiple satellite functions into a single unit. Dubbed the Integrated Avionics Package (IAP), this system acts as the “brain” of the satellite, handling crucial operations like:
Telemetry & communication
On-board data processing
Positioning & navigation
Power management

Key Benefits of the IAP System
Reduces weight and size by replacing multiple discrete units with a single module.
Lowers power consumption, enhancing satellite efficiency.
Simplifies integration, making mass production easier for future missions.
Supports I-1K class spacecraft, ensuring compatibility with various satellite platforms.

Collaboration with Industry Partners
ISRO is seeking industry partners to assist in:
Developing and integrating the IAP system.
Conducting rigorous testing for ground validation.
Ensuring scalability for mass production over the next five years.

India’s Growing Satellite Fleet
As of December 2024, India operates:
22 satellites in Low Earth Orbit (LEO)
31 satellites in Geosynchronous Orbit (GEO)
Active deep-space missions like Chandrayaan-2 orbiter and Aditya L-1
With 261 successful launches in 2024 alone (97% success rate), ISRO’s advancements in satellite technology are setting new benchmarks globally.
