Payload Capacity	Up to 500 kg to 500 km planar orbit; 300 kg to Sun-Synchronous Orbit (SSO).
Stages	3 stages (all solid fuel) + a liquid-based Velocity Trimming Module (VTM) for precise orbit injection
Integration Time	Quick turnaround of 72 hours (vs. 70 days for PSLV).
Manpower	Can be integrated by a team of only 6 people.

Exam TIP

Remember the difference:
SSLV → Small satellites, low cost, quick launch
PSLV → Polar missions, versatile
GSLV → Heavy payloads, geostationary orbit
