Why We Exist

Satellites are frozen in time.
We fix that.

Every microsatellite launched today becomes an expensive, immutable object. GOATSat introduces the interface that changes the equation.

Status Quo — Broken

One sensor fails.
Replace the whole spacecraft.

  • 🛰️
    Replacing a 200 kg satellite costs $30–100M when a single subsystem fails prematurely.
  • 🗑️
    Every discarded satellite becomes orbital debris — threatening LEO sustainability for all operators.
  • 🔒
    Hardware is frozen at launch day. No upgrades, no iteration — new sensors require entirely new buses.
  • 📈
    Microsatellite CAGR is ~20% through 2030. Wasted capital compounds at exactly that rate.

The GOATSat Era — Modular

Upgrade the payload.
Keep the bus.

  • 🔌
    A failed sensor? Dock a replacement module. Pay for the component, not the spacecraft.
  • ♻️
    Stranded modules stay passively docked — zero debris risk. New modules restore functionality additively.
  • 🔄
    SpaceFibre + CAN-FD standard interface means any certified module works with any compatible host.
  • 🌍
    Universal standard drives an ecosystem. Every new adopter increases value for all others.
Technical Standard

Three layers.
One universal interface.

GOATSat v0.1 defines mechanical, electrical, and software contracts — independently upgradeable, fully interoperable.

⚙️

Mechanical Layer

Funnel-guided blind-mate docking collar with keying features, passive retention, and thermal interface pads — designed for 10–100 kg microsatellite structural tolerances.

M-LAYER · GOATSat v0.1 Click to expand →
⚡

Electrical Layer

6-group hot-plug pin sequencing with eFuse inrush control and hardware fault isolation at every transition.

E-LAYER · SpaceFibre
🧩

Software Layer

Module discovery protocol over CAN-FD / SpaceWire — capability negotiation, telemetry, and firmware versioning without bespoke host firmware.

S-LAYER · CAN-FD
3
Interface Layers

Mechanical, Electrical, Software — independently upgradeable, fully specified.

8
FSM States

Deterministic state machine from S0 (safe) to S7 (nominal) governs every docking sequence.

0
Modules Removed

Failed modules stay passively docked. New modules restore capability — no debris created.

Business Architecture

We don't build the trucks.
We write the rules.

01

Adopter Licensing

Satellite manufacturers pay an annual license to integrate the GOATSat interface and use the certification mark — a competitive differentiator in procurement.

Annual Fee / Mfr. $50k
02

Module Royalties

Third-party vendors who manufacture GOATSat-compatible upgrade modules pay a royalty per unit. The dominant long-run stream — high-margin and self-reinforcing.

Royalty Rate 5.0%
03

Certification Fees

One-time fee to test and validate host satellite and module compliance with GOATSat v0.1. Benchmarked against AS9100 and DO-178C aerospace certification analogues.

One-time / Adopter $20k
