PiLogic — Manifest

Milliseconds. Telemetry to verdict.

Proud to work with

A current channel goes to noise in a simulated run. Someone has to find out why.

From that one channel, a threshold can only say the numbers look wrong. Manifest reads every sensor on the bus together, so it can say what happened: a routine power-source switch, and one sensor failing at the same moment. The spacecraft is healthy.

The verdict arrives in milliseconds, on a single CPU core.

What it does

Built from your schematic. Running on your hardware.

Manifest watches every sensor as telemetry arrives, ranks every possible cause with an exact probability, and runs onboard or on the ground.

How it works

Your schematic in. An exact model out.

Four automated steps from your diagram to a model that answers in milliseconds. Under a day for the first, about 30 minutes per variant after.
