How is the battery?

Timestamp, voltage, current. Temperature helps.

Drop the telemetry here Yamcs · COSMOS · Grafana · SatNOGS · CSV · xlsx · Parquet · JSON · zip. Up to 8 MB.

No file? · (synthetic, labelled)

Cryptic channel names? (XTCE, COSMOS, MIB or a channel list): its descriptions and units name the columns. Read, never kept.

GEO and MEO: the array's remaining life

With one current per array string and the shunt current, the analysis gives the years the array keeps covering the load on the worst day of the year.

Array pointing Launch date, optional Extension to check, years Propellant left, years, optional Watts per transponder, optional Bus voltage, V, optional

How much energy per orbit?

In orbit? Name or NORAD number

Altitude, km Inclination, ° Battery pack Array at beginning of life, W Platform Horizon

More settings

Orbit file: TLE, CCSDS OMM or OEM. Replaces altitude and inclination. Start, UTC Node, ° Element epoch, UTC (optional, for altitude/inclination without a TLE) Argument of latitude, ° (0 = ascending node at the epoch) Satellite Capacity, Wh Cell State of health, % Initial state of charge, % Depth-of-discharge limit, % Battery temperature, °C Attitude Array age, years Housekeeping, W Heater, W Reserve, % SoC

The node defaults to the Sun's direction: noon–midnight plane, longest shadows. Add 90° for dawn–dusk.

Can your plan run without wearing the battery down?

Edit the tasks or upload your plan. Step 3 is the energy they run on.
