VSAT latency refers to the delay in data transmission caused by the distance signals travel to and from satellites, typically geostationary ones. Marine VSAT systems usually have a latency of 600-800 milliseconds. While sufficient for basic browsing, email, and some VoIP, it can affect real-time applications like gaming or video conferencing. New low-earth orbit (LEO) technologies aim to reduce latency, but traditional VSAT remains reliable. Understanding latency is crucial when designing mission-critical marine networks, especially for navigation and communication systems onboard.
