Orbits
Know the orbit behind every decision.
Bring tracking measurements and orbital data into one workflow. Determine the orbit, inspect the evidence, and predict where your spacecraft will be next—with the source and age of its orbit in view.
Inside VALAR
Know which orbit you are using
Keep computed and public-catalog data distinct, with a shared view of orbit freshness across the products that depend on it.
Read the orbit-age and ephemeris releaseThe workflow
From observations to orbital products
An orbit solution is the evidence behind a state estimate. Ephemerides carry that estimate forward for the teams and systems that depend on it.
Bring in tracking and orbital data
Import measurements from onboard and ground sensors, including position and velocity, range, Doppler, and angular observations. Bring in externally produced state vectors when those are your starting point.
Determine and inspect the orbit
Configure an orbit-determination run and review its solution: state estimate, covariance, measurement residuals, and convergence. Use that evidence to assess whether the result is suitable for the next operation.
Reconstruct maneuvers in the solution
Account for maneuvers in orbit determination and inspect the reconstructed result alongside the planned burn. Reconstruction belongs with the orbit solution, connecting post-burn tracking back to the maneuver decision.
Predict and deliver
Propagate orbital states into ephemerides, compare orbital products, and inspect ground tracks. Export products for other systems or configure an ephemeris push task for supported catalog destinations, with a delivery history to review.
What you bring
- Tracking measurements and sensor information
- Imported state vectors and available orbital data
- Spacecraft model and maneuver information
What you work with
- Orbit solutions with state, covariance, and fit diagnostics
- Reconstructed maneuver information within orbit solutions
- Predicted ephemerides, comparisons, and ground tracks
Connected operations
The next decision uses the same context.
Plan from the orbit in Maneuvers
Use orbital state and spacecraft context to compute alternatives, then return to Orbits for reconstruction after the burn.
Reassess an encounter in Conjunctions
Use your spacecraft's orbital state to recompute an assessment and examine the encounter as new information arrives.
Predict opportunities across operations
The same orbital context supports ground contacts, area access, attitude products, and the shared Map.

Walk through your operational workflow.
Bring a representative tracking file, your spacecraft model, and an example of the orbital product your ground segment needs. We can walk through the inputs, solution review, and delivery together.
