Design in an afternoon
Move the orbit, the radiator, the battery. Watch a year of results come back before you have finished your coffee.
Orbital compute, simulated
Fly it before
you launch it.
Annatar simulates data centers in orbit — sunlight, heat, shadow, bandwidth — and tells you what a fleet delivers before anyone spends a dollar on hardware.
Request access →Scheduled, not assumed
Real work placed on real racks, hour by hour, through every eclipse season — not a duty cycle and a hopeful margin.
Numbers you can defend
Compute delivered, hours lost to heat and shadow, and every assumption that produced them, written down.
Free for research
