Stop Designing for the Bus ICD
Start Designing for your Mission

“Standardized” common spacecraft buses often force mission owners to compromise objectives to fit the payloads into a standardized bus ICD. While standardized bus providers routinely advertise simple integrations up front, novel payload integration campaigns often result in significantly increased costs, schedule and risk - instead of offering price certainty or mission assurance.

We don't have a bus ICD

We begin with your Payload ICD then generatively design a payload tailored bus around your mission objectives - using a flight proven design system and TRL9 spacecraft components.

We replace “one-size-fits-all” standard bus options with Proteus engineering, where a custom spacecraft is autonomously designed and built around your payload.

We excel at rapidly delivering payload tailored bus solutions involving power, thermal, pointing and jitter issues.

Standardized Buses were invented in 1966

Proteus delivers a modern solution for the needs of this century

Standard Buses

Protean Buses

Your payloads must fit their ICD
We don't have an ICD - we design a structure and arrange TRL9 components around your payload and we find bus solutions no human can find
Massive labor payload integration campaigns, using Office files and meeting invites to communicate
We use AI & Autonomy in a fully deterministic, traceable, physics anchored, TRL9 system, delivering Parametric B-Rep CAD and standard engineering deliverables
Primes use their own heritage components - with a few untested components on each new bus
We use the largest TRL9 flight heritage COTS spacecraft component database in the world
Pick from one or two bus designs
In less than 7 days from kickoff, you can visualize thousands of payload tailored, mission closing bus options on the trades that matter to you
Changing your mind = huge regrets
Change your mind without regret - instantly redesign
Mission, cost and schedule uncertainty
Instant visibility on BOM, Cost, Schedule, Lead Times, Supply Chain, Launch Options, Ops Costs, engineering certainty and more
