Which launch vehicle does ISRO use to place IRNSS navigational satellites into orbit?
ASpace shuttle
BGSLV
CPSLV
DLuna launcher
Answer & Solution
Correct answer: C. PSLV
1. IRNSS is the Indian Regional Navigation Satellite System, used to fix precise latitude and longitude.
2. The chapter's satellite table lists PSLV as the launcher for navigational (IRNSS) and Earth observation (IRS) satellites.
3. GSLV (rule out) is used for INSAT/GSAT weather, communication and broadcast satellites.
4. Therefore IRNSS is launched by PSLV.
