Estimate satellite internet latency budget from explicit engineering assumptions. The tool shows the primary planning value plus supporting figures so you can see how traffic, margin, geometry, or path components affect the result. Use measured inputs when available and treat the output as a design estimate rather than a service guarantee.
The total is a budget, not a guaranteed measurement. Each component is visible so an engineer can identify the largest contributor and test whether a target has enough margin.
Planning estimate only. Validate assumptions against equipment specifications, measurements, and local operating conditions.
Adding 35 ms, 35 ms, 20 ms, 15 ms, 25 ms produces 130.0 ms one-way and 260.0 ms estimated round-trip latency.
The main result is one-way. The calculator also shows a simple round-trip estimate equal to twice the one-way total.
Queueing changes with load. A margin lets the design reserve time for variable waiting delay without treating it as a fixed path component.
Only if you include endpoint or application processing in the processing input. The automatic doubling does not add a separate server-response time.
Yes. Measured values usually make the budget more useful, provided every value represents the same direction and operating condition.
Test routing, server location, network load, transport behavior, and measurement methodology can all differ from the modeled path.
| Component | Included delay |
|---|---|
| Access | Last-mile or radio path |
| Propagation | Signal travel time |
| Queueing margin | Variable waiting allowance |
