Space Data Network

An open network for space traffic management

Space Data Network

An open, decentralized, censorship-resistant network for space data, software, and services.

Digitally signed and optionally encrypted. Built on open standards, software, and algorithms.

Why it matters

Data Infrastructure Hasn’t Kept Up With The Growing Space Economy

Every satellite owner-operator needs timely access to vital data, including what is coming close. How well that works comes down to three things: how the data is organized, how fast it moves and whether it can be trusted.

Organization

TodayOrbit data is spread across many websites, each with its own login and its own kind of file.

On the networkOne open standard that any software can read, on one network every source can publish to.

Speed

TodayEveryone downloads the same big files, again and again, every time they change.

On the networkEach update is published once and passed from node to node.

Security and attribution

TodayFiles move from system to system with nothing to prove who made them or that nobody changed them.

On the networkEvery record is digitally signed by its source and checked by every node. Sold data opens only for the buyer.

What the network is

One Shared Catalog, Built From Every Source

No single tracking network sees everything in orbit. The network combines every source into one catalog, keeps each record digitally signed by whoever produced it, and shows how each result was reached.

Many kinds of sources flow into digitally signed records, then an open recipe, then one catalog shared by every node
Any source, one open catalog.

Any source can contribute

Radars, telescopes, satellite operators, universities and other nations. Anyone can publish, free or for sale.

Every record has a source

Digitally signed by whoever produced it, kept exactly as published, with its margin of error whenever the source gives one.

Results anyone can check

Each version of the catalog lists its inputs and method. Anyone can rerun it and get the same answer.

Censorship resistant

No central server or gatekeeper. Records pass from node to node, so no single party can remove them, alter them unnoticed, or shut a publisher out.

For your organization

Four Ways To Join The Network

Start in a web browser at SpaceAware.io, the network’s portal, with nothing to install. To put your organization on the network, install the free network software, called a node, on a computer or server you control. Each step keeps everything from the one before.

  1. 1

    Nothing to install

    Use the portal

    At SpaceAware.io, see every tracked object, follow live updates and run orbit analysis in your browser. Every record shows who produced it.

  2. 2

    Install a node

    Put your organization on the network

    A node publishes who you are, digitally signed, and holds your organization’s keys: one to sign what you publish, one to open data sent only to you. It works alongside your existing systems.

    Identity and keys →
  3. 3

    Your node ยท your data

    Publish your data

    Share orbits, observations and warnings in open standard formats, digitally signed at the source. Give them away or sell them on your own terms.

    Publish data →
  4. 4

    Always-on node

    Offer software and services

    Run analysis software and services that other operators use and pay for, and help carry the network’s traffic.

Trust

Knowing Whose Data To Trust

Every publisher signs with a digital key. Adversarial security shows whether that key is still safe by tying it to money anyone can see.

One key, two jobs

The key that signs a node’s records also controls cryptocurrency accounts. Identity and value share one key.

Value as a bond

The owner deposits funds in those accounts, and anyone who relies on the source can add more to raise the stakes.

Attackers prove the point

Whoever steals the private key can take the funds instantly and anonymously, so they will. Funds that stay put mean the key has not been stolen.

Checked continuously

Balances are public and update continuously: a live signal anyone can check, instead of taking a certificate on trust. Each node decides whose data it accepts.

Install The Network Software

Step-by-step guide →

Desktop app

Easiest. Installs a node and opens its dashboard.

Terminal

Installs the node as a background service.

macOS / Linux
curl -fsSL https://spacedatanetwork.org/install.sh | bash
Windows PowerShell
irm https://spacedatanetwork.org/install.ps1 | iex

Server bundles

Docker

Identity and data live in the sdn-data volume.

docker run -d --name sdn --hostname sdn --restart unless-stopped \
  -v sdn-data:/app/data \
  -p 127.0.0.1:5001:5001 -p 4001:4001 -p 4001:4001/udp \
