Scenario links & saves

Applies to Orbit Visualizer v1.1 · Updated

The Orbit Visualizer's Copy Link button packs your entire scenario — every object, its propagator, maneuvers, and ground sites — into one shareable URL. Save / Load stores named scenarios in your browser for free; ExoAtlas Pro members can also save up to 50 scenarios to the cloud and reload them on any device.

Click Copy Link in the sidebar footer to copy a URL that encodes the whole scenario. The link is a compact base64url payload appended to the app as ?s=2.<payload>, so opening it in a fresh tab rebuilds the scenario exactly — propagator badges and all. The button stays disabled until you have at least one object; on success the app reports “Link copied to clipboard.”

The encoding captures, per object:

  • the object name, input type (classical elements, state vector, or TLE), and its selected propagator (always included);
  • for a TLE object, both element-set lines; otherwise the six classical elements (to six significant figures) and the epoch;
  • any maneuvers — time, frame (RIC or ECI), the three ΔV components, and the label;
  • your ground sites (name, latitude, longitude, altitude, elevation mask) and the active Analysis tab.

Start a scenario, then press Copy Link to share it:

A permalink has a practical length ceiling of about 1,900 characters. If your scenario would exceed it — typically after adding a large constellation group — the app does not copy a truncated link. Instead it shows “Scenario too large for a link — use Save instead.” Use Save / Load (below) for scenarios that big.

The ?s= permalink takes precedence, but the app still reads its original query-parameter deep links — ?tle1=…&tle2=…, classical-element links such as ?a=7000&e=0.001&i=51.6, and catalog presets like ?catalog=iss. Links you shared before permalink v2 still resolve. See the URL API for every supported parameter.

Save / Load: local and cloud

Click Save / Load to open the save manager. It has two areas:

  • Local (this browser) — type a name and click Save locally to store the scenario in your browser. Always free, no sign-in; local saves live only in that browser and profile.
  • Cloud Pro — signed-in Pro members click Save to cloud and reload scenarios on any device. Signed out, the panel prompts you to sign in; signed in on the Free plan, it notes that cloud scenarios are a Pro feature.

Cloud storage is enforced on the server: up to 50 scenarios per account, each up to 100 KB. If you hit either limit the app tells you (“Scenario limit reached” or “Scenario too large to store in the cloud”) rather than failing silently.

Mini-FAQ

Does a share link expire or phone home?

No. A Copy Link URL is self-contained — the scenario is encoded in the link itself, so it needs no server and does not expire. Anyone who opens it rebuilds the same scenario locally.

Do I need an account to save?

No for local saves and share links, which are always free. Cloud saves require signing in with an ExoAtlas Pro account; they are the one scenario feature enforced on the server.
