Apsia exists to make that budget visible, forecastable and cheap to spend well. We build it in Talavera de la Reina, Spain, for operators across Europe.
A satellite's energy follows orbital geometry and electrochemistry. Models start there; telemetry calibrates them. We do not fit curves to data we could have derived.
Every figure ships with what it was computed from and how sure we are. A number without a source line does not appear on this site.
The models are validated on public flight data and published cell tests before any customer sends a byte. Every published figure has a control arm and a held-out test. The numbers are on the home page and in the white paper.
Operators know their spacecraft. Apsia gives them the energy picture and the cost of each choice. People approve every change.

If you operate satellites and want to shape the product, the fastest way in is a pilot.
