  7. 7. Calculating the latency and ping timing ©3G4G Latency is defined as the time it takes for a source to send a packet of data to a receiver. In simple terms, half of Ping time
  8. 8. Calculating the latency and ping timing ©3G4G • Speed of light = 3 x 108 m/s or 3 x 105 km/s • RF signals travel the same speed as light • Ground station to satellite = 35786 km / 3 x 105 km/s = 120 ms • Satellite to plane approx. 120ms • Ground station to server approx. 10ms • Plane to WiFi approx 50ms (processing delays) • Total latency approx. = 300ms • Ping time, at least 600 ms approx.
