Technical Questions (2025)

Q1: Satellite Communication - 2025 Real Question

Problem: Calculate the signal propagation delay for a geostationary satellite communication link. (Geostationary altitude = 35,786 km, speed of light = 3×10⁸ m/s)

Solution:

Distance = 2 × altitude = 2 × 35,786 km = 71,572 km
Propagation delay = Distance / Speed of light
= 71,572,000 m / 3×10⁸ m/s ≈ 0.24 seconds
