Product overview

One mission. Every question.

Arksa is the operating system for space missions. Design an orbit or a whole constellation, analyse it on a validated engine, share it with a link and run it from a plan you approve.

01What Arksa is

One workspace for the whole life of a mission: design the orbit, analyse what it can do, share it with the people who need it, and operate it from a plan you approve.

Engine first

One validated engine, so a number never changes with the screen you read it on.

Checked on every change

Validated against independent tools and published references: 350+ validation cases, all passing. See the results.

Yours when it must be

On Sovereign, compute and files stay on your own servers.

Validated: orbit geometry against a published textbook example →

02The workflow

Four moves, one model

Each step reads and writes the same mission, so nothing is retyped between design, analysis, review and operations.

  1. Design

    Lay out the orbits

    Turn requirements into orbits and constellations, then fly them as precisely as the question needs.

    • Every orbit type
    • Constellations
    • Manoeuvre planning
  2. Analyse

    Ask every question

    Access, coverage, power, link budgets, conjunctions, lifetime, networks and trade studies, all on the mission you just drew.

    • Heavy jobs run on Arksa compute
    • Every review question, one model
    • Results you can trace
  3. Share

    Hand it over

    With team accounts, share any view with a link: reviewers open it exactly as you left it. Reports export as a self-contained HTML page, a PDF or an evidence pack.

    • Read-only share links that expire, with team accounts
    • Team roles and version history, with team accounts
    • Reports in the formats your team uses
  4. Operate

    Run it from a plan

    Ask for an outcome in plain English, such as "image Tokyo every pass this week", and approve the timed plan Arksa drafts.

    • Plans timed from your scenario
    • Approve, reject or review later
    • Every decision on the record
Every capability in depthMission OS

The mission, live

The Arctic Earth-observation example mission, flown from today and drawn on the real Earth under today's Sun.

04The engine

FIG.Nodal drift

Physics you can read.

Earth's oblateness turns every orbit plane. A sun-synchronous orbit turns with the Sun and keeps its local time; the 53° shell sweeps through every local time. Arksa shows both, for every satellite.

SSO drift
+0.986°/day, tracking the Sun
53° shell
−4.38°/day at 600 km

FIG.Validation

Checked against the book.

The transfer from low orbit to geostationary matches the published textbook answer. It is one of the reference cases checked on every change.

05One model, every surface

One model, every surface

One mission, one model. Every surface shows the same results.

  • Web studio

    A 3D globe and 2D map with every analysis module. Invited teams open it on the web during early access.

  • Share links

    With team accounts, read-only links that expire, so a reviewer sees exactly what you see.

  • API on request

    API access for pilot and Mission teams, on request.

  • Server

    Accounts, roles, licences and missions on the same engine. Team cloud, accounts and billing open with general availability; Sovereign is built to run on your own servers.

06Where your work lives

Your data, your call

Early access today: single-user studio by invitation. Team cloud, accounts and billing open with general availability. Sovereign is built to run on your own servers.

More seats, more compute and shared workspaces come with Team and above. Plans and pricing.
