An early warning system in space to detect debris and other hazards to Indian satellites.
What is Project NETRA (Network for space object Tracking and Analysis)?
Under the project, the ISRO plans to put up many observational facilities: connected radars, telescopes; data processing units and a control centre.
They can, among others, spot, track and catalogue objects as small as 10 cm, up to a range of 3,400 km and equal to a space orbit of around 2,000 km.
Significance of the project:
- The project will give India its own capability in space situational awareness (SSA) like the other space powers — which is used to ‘predict’ threats from debris to Indian satellites.
- NETRA’s eventual goal is to capture the GEO, or geostationary orbit, scene at 36,000 km where communication satellites operate.
- The effort would make India a part of international efforts towards tracking, warning about and mitigating space debris.
