Tested on real satellites.

The same battery analysis you would run on yours, on public telemetry from ground stations around the world.

How fast each battery is losing ground.

Each line is one satellite: the dot is its health trend in % per year, the bar its range. In amber, the ones Apsia calls falling.

What the trend measures

The battery voltage at the end of each shadow, compared across passes with the same load, temperature and shadow length. A fall means the battery holds less than it did.

When it says falling

Only when the whole range sits below zero. A satellite with too little data is left unresolved, never called.

How far it looks ahead

The voltage the station will see 30 days ahead, scored on weeks the model never saw.

See all the data

Four batteries failed. Apsia saw all four coming.

Days before AMSAT announced each failure. Amber: Apsia's alert. Grey: the day the voltage first crossed the fixed 3.6 V limit. From the frames amateur ground stations received and published.

Your fleet, in the same view.
