Which model holds your footprint?
Minimum EIRP is the weakest satellite signal a model can work with. Set the weakest point of your route and the margin you want, and this names the smallest model that holds it — then shows what the next size up buys and what it weighs.
Inputs
Not sure of the number?
Look at the satellite operator's footprint map and read the contour that covers the weakest point of your route — usually a coastal edge or the northernmost port. If two contours cross the route, use the weaker.
How to read a footprint →This is a selection aid, not a link budget. It compares your footprint figure against the published minimum EIRP of each model. Antenna gain, G/T, elevation angle, cable loss and actual rain attenuation are not modelled — a link budget for a specific satellite is done per vessel.
