List of 10 LEO Satellite Internet Questions and Answers

Question 1: What is LEO satellite internet?

Answer 1: It provides internet access using satellites orbiting in Low Earth Orbit (~500 to 2000 km altitude), enabling low latency broadband.

Question 2: How is LEO different from GEO satellites?

Answer 2: LEO satellites have lower latency (~20 to 40 ms) and need many satellites for full coverage, unlike GEO (35,786 km) with higher latency (~600 ms) and fewer satellites.

Question 3: What are the key benefits of LEO satellite internet?

Answer 3: Global coverage, low latency, high bandwidth and service in remote or underserved areas.

Question 4: What are the challenges in LEO satellite deployment?

Answer 4: High deployment cost, satellite collision risk, regulatory issues and complex network management.

Question 5: What frequency bands are used in Starlink?

Answer 5: Ku-band (12–18 GHz), Ka-band (26.5–40 GHz), and optical laser links for inter satellite communication.

Question 6: Name some LEO satellite internet providers.

Answer 6: Starlink (SpaceX), OneWeb, Amazon Kuiper, Telesat Lightspeed, and China’s GuoWang.

Question 7: How does a ground terminal connect to LEO satellites?

Answer 7: Using a phased array antenna that tracks satellites in real time for continuous connectivity.

Question 8: How is handover managed in LEO networks?

Answer 8: Seamless satellite to satellite and satellite to ground handovers are done using software defined networking and predictive algorithms.

Question 9: What applications benefit from LEO internet?

Answer 9: Maritime, aviation, remote education, rural broadband, military and disaster response.

Question 10: What is the impact of LEO mega constellations on space debris?

Answer 10: It increases collision risk; hence, operators like SpaceX are using autonomous deorbit and collision avoidance systems.
