Science & Technology
1. NVS-03 completes its first orbit-raising manoeuvre
ISRO reported that NVS-03, launched aboard GSLV-F18 late on 30 October, completed its first planned orbit-raising manoeuvre on 31 October 2026. The spacecraft is healthy, and further manoeuvres are planned before placement in its intended geosynchronous orbital slot; it should therefore not yet be described as operational.
Important exam facts
- GSLV-F18 injected NVS-03 into a 170.3 km × 38,080 km orbit at 23:51 on 30 October 2026.
- The first liquid-apogee-motor burn lasted 2,174.8 seconds and produced an estimated 5,477.6 km × 37,833.4 km orbit.
- NVS-03 is the third satellite in the next-generation navigation series supporting continuity of IRNSS/NavIC services.
- It carries an indigenous atomic clock and adds an L1 signal alongside L5 and S-band signals.
- ISRO plans to place it in geosynchronous orbit at 111.75° East.
Static GK connection: Revise NavIC/IRNSS, geosynchronous transfer and geosynchronous orbits, atomic clocks, satellite-navigation signals and the role of orbit-raising manoeuvres.

2. MeitY launches DEPA for AI Training handbook
The Ministry of Electronics and Information Technology launched a handbook for applying the Data Empowerment and Protection Architecture to AI training.

Important exam facts
- The handbook was unveiled in Bengaluru with support from the iSPIRT Foundation.
- The framework combines contractual permissions, controlled computing environments and privacy-enhancing safeguards.
- Data provenance is intended to trace the origin, permission and use of data throughout model training.
- The stated design principle is that the model travels to the data rather than the data moving to the model.
Static GK connection: Connect DEPA with consent-based data sharing, privacy, data fiduciaries, purpose limitation, provenance, confidential computing and responsible-AI governance.
