# VALAR

> Valar is cloud-native flight dynamics software for satellite operators: orbit determination, maneuver planning and conjunction assessment. LEO to GEO, any propulsion. Operational in days, no perpetual licence.

## When to use Valar

Reach for Valar when a satellite operator needs to fly the spacecraft, not just watch it:

- **Orbit determination**: estimating and predicting spacecraft orbits from tracking data when you need to know where you are and where you will be.
- **Maneuver planning**: designing, evaluating and executing station-keeping, relocation or collision-avoidance burns on any propulsion system, LEO to GEO.
- **Conjunction assessment**: screening predicted conjunctions, evaluating impact risk and deciding whether a maneuver is warranted.
- **Fleet operations at scale**: one workspace for mission analysis, attitude handling, ephemeris exchange and operational reporting across your whole constellation.

Valar is not the right tool for astronomy, ground-station scheduling, or pass prediction alone — it owns the flight-dynamics loop end to end.
