Orbit determination & prediction
Know where you are, and where you'll be. VALAR estimates your spacecraft's orbit from tracking data and predicts its path forward, the foundation every other function builds on.
Flight dynamics software for modern spacecraft operations.
A real-time decision layer for orbit determination, maneuver planning, and conjunction assessment. Sits inside the ops loop, alongside mission control, not instead of it.
Our Clients
Used by operations teams that already fly.
From first missions to established fleets.
What VALAR does
Every tier runs the same six functions. What changes is how far each one goes, and what it takes to operate.
VALAR is flight dynamics software for satellite operations: orbit determination, maneuver planning, ephemerides, and conjunction assessment. LEO to GEO. Impulsive or continuous propulsion.
Orbit determination & prediction
Know where you are, and where you'll be. VALAR estimates your spacecraft's orbit from tracking data and predicts its path forward, the foundation every other function builds on.
- - Essential: Orbit determination and prediction for one spacecraft, refreshed as tracking data arrives.
- - Operations adds: Multiple tracking sources feed the same estimate, so accuracy holds up as operational tempo increases.
- - Enterprise adds: Advanced mission optimization tunes estimation and propagation across your whole fleet.
Attitude determination & control
Orientation is a first-class input to the physics. Define how each spacecraft points, inspect it as quaternions and Euler angles, and let drag and solar radiation pressure act on the shape it actually presents.
- - Essential: Built-in pointing modes: Earth-pointing, Sun-pointing, inertial, velocity-tracking, or free drift, for one spacecraft.
- - Operations adds: Custom attitude profiles and scheduled transitions folded into repeatable operations for up to five spacecraft.
- - Enterprise adds: Attitude handled at fleet scale, with AEM exchange coordinated across formations and constellations.
Maneuver planning
Plan the burns that shape your mission. VALAR turns target orbits into executable maneuver plans, with the delta-V cost of every option laid out before you commit.
- - Essential: Maneuver planning for one spacecraft's mission targets.
- - Operations adds: Advanced maneuver planning for recurring operations: station-keeping, orbit maintenance, and routine re-planning.
- - Enterprise adds: Coordinated fleet operations: maneuvers planned with awareness of every spacecraft they affect.
Conjunction analysis & space traffic
Watch for close approaches before they become emergencies. VALAR ingests conjunction alerts from Space-Track and EU SST, classifies the risk, and gives you the means to act on them.
- - Essential: Conjunction analysis for your spacecraft against everything else in orbit.
- - Operations adds: Advanced conjunction workflows: recomputed risk, trend analysis, and Pareto-filtered avoidance options.
- - Enterprise adds: Formation and constellation support screens every spacecraft in the fleet, not just one at a time.
Orbital events & automation
The recurring computations a mission runs daily: eclipse crossings, apsis passages, ground-station passes, computed continuously, with automation watching what matters between decisions.
- - Essential: Orbital events computed for your spacecraft, with standard automation covering the routine checks.
- - Operations adds: Automated operations run the monitoring-and-response loop continuously, not just when someone is watching.
- - Enterprise adds: Enterprise deployment puts that automation inside your own operating environment and requirements.
API, integrations & support
Flight dynamics that fit your ops floor. Every capability is reachable programmatically, connects to your existing tools, and comes with humans when timing matters.
- - Essential: API access to every capability in the tier.
- - Operations adds: Standard integrations connect VALAR to your existing tools, with priority support when a window is closing.
- - Enterprise adds: Custom integrations built to your architecture, backed by a custom SLA and support agreement.
Using VALAR from an agent
Everything public about VALAR is published in machine-readable form at predictable URLs, so agents and scripts never have to scrape pages:
- - Pricing tiers as markdown at https://valar.space/pricing.md.
- - A read-only MCP server (Streamable HTTP) at https://valar.space/mcp, with tools including valar_get_pricing, valar_get_site_map and valar_get_changelog_latest.
- - An OpenAPI description of every public endpoint at https://valar.space/openapi.json.
- - Agent guidance and the full resource index at https://valar.space/llms.txt.
Responses carry IETF RateLimit-Policy and RateLimit headers so callers can self-throttle; API errors are RFC 9457 problem details carrying a stable code, a human-readable detail, and an actionable resolution hint.

What industry experts are saying
Mark Thompson
CEO of Gravity Space LLC
“Valar's all-in-one flight dynamics platform let us spin up full mission control in days. We consolidated orbit determination, maneuvers, and traffic monitoring into a single pane of glass. We reduced operating costs by about 50% – no upfront licences, no patchwork tools, no integration fees… just launch and go.”
Akshay Gulati
CTO of Infinite Orbits
“Valar has been a great partner in providing bespoke solutions to IO's unique flight dynamics requirements, analysis, tracking and maneuver evaluation needs in a swift manner. Looking forward to our continued collaboration.”
Gurvinder Chohan
CEO of Reliasat
“From tracking data ingestion to burn execution, Valar keeps our flight dynamics operators focused on the mission, not the tooling.”
Scale the fleet without scaling ops chaos.
Real-time flight dynamics in the control room. Automation native, operator driven.
