Quick scan: Starlink and Low Earth Orbit satellites
बातमीत का?
Why Starlink beats geostationary satellites on lag: the LEO altitude fact GS3 space questions test
Starlink uses Low Earth Orbit satellites for low-latency broadband.
Why it matters: asked in UPSC 2002
What you need to know
2 मिनिटे
Starlink's constellation operates mainly in Low Earth Orbit, a few hundred kilometres above the Earth, which gives low-latency broadband compared with geostationary satellites.
Satellite broadband regulation in India is the subject of the TRAI recommendation on network provider authorisation.

महत्त्वाची तथ्ये
Remember these
- Starlink's constellation operates mainly in Low Earth Orbit, a few hundred kilometres above the Earth.
- LEO gives lower latency than geostationary satellites, which sit far higher (about 36,000 km).
- Satellite broadband regulation in India is linked to the TRAI recommendation on network provider authorisation.
- TRAI is the telecom regulator; it recommends, while the Department of Telecommunications licenses.

How the exam will ask it
पूर्व
- Statement: Low Earth Orbit satellites generally offer lower latency broadband than geostationary satellites. (Correct)
- Statement: Starlink's constellation operates mainly in Low Earth Orbit, a few hundred kilometres above the Earth. (Correct)
- Statement: TRAI's recommendation on network provider authorisation bears on satellite broadband regulation in India. (Correct)
मुख्य
GS3 (Space and telecom). Issue: satellite broadband from LEO constellations promises low-latency connectivity, but needs a clear authorisation framework. Policy: the TRAI recommendation on network provider authorisation shapes how such services are regulated in India. Implication: wider rural reach versus spectrum and competition concerns; way forward is transparent, timely authorisation with safeguards for security and domestic players.
