Live orbital console • simulated data

Orbit is getting crowded. We keep it clear.

APOGEE is Ace Hacker's orbital-intelligence engine. It tracks every object in orbit, predicts conjunctions before they happen, optimizes constellation coverage and collision-avoidance maneuvers with quantum solvers, and flies spacecraft autonomously when the ground can't reach them.

The whole orbital picture, from catalog to command.

APOGEE pairs each part of space operations with the right computation, deep learning to see and predict a chaotic sky, quantum optimization to plan maneuvers and constellations, and onboard autonomy for when a spacecraft is on its own.

Track • Instrument 01

You can't protect what you can't see.

Tens of thousands of objects cross low Earth orbit, observed only in brief, noisy glimpses from radar and optical sensors. Track fuses those glimpses into a precise, continuously-updated catalog: where every object is now, and where it will be.

  • 01
    Orbit determinationA learned estimator fuses sparse, heterogeneous observations into an orbit with a full covariance, tightening the fit as new data arrives.
  • 02
    High-fidelity propagationDrag, solar radiation pressure, and higher-order gravity are modelled so predicted positions hold over days, not hours.
  • 03
    Sensor taskingThe engine decides which object to observe next to shrink catalog uncertainty fastest, an active-learning loop over the whole sky.

Predict • Instrument 02

A collision is cheap to avoid and catastrophic to ignore.

One collision can spawn thousands of new fragments and trigger a cascade that renders an orbit unusable for decades. Predict screens the entire catalog for close approaches and quantifies the probability of collision long before the moment of closest approach.

Optimize • Instrument 03

Move the right satellite, the right amount, once.

A maneuver spends fuel and disrupts the mission, so it must be minimal, and coordinated across a whole constellation. Optimize plans fuel-optimal avoidance and coverage as combinatorial problems, exactly where quantum and hybrid solvers earn their place.

    Fuel-optimal avoidanceThe smallest burn that drops collision probability below threshold while respecting mission and pointing constraints.
  • 02
    Constellation coveragePhasing and slots are optimized so a fleet keeps its target coverage after any maneuver.
  • 03
    Quantum where it countsAssignment and scheduling are cast as QUBOs and solved with QAOA and hybrid methods; simple cases stay classical.

Autonomy • Instrument 04

Out of contact is not out of control.

A spacecraft is in view of the ground for only minutes per orbit. For the rest, it is on its own. APOGEE runs onboard: it watches telemetry for anomalies, diagnoses faults, and takes safe, bounded action in real time, then reports back.

Benchmarks • honest numbers

Where quantum earns its place, and where it does not.

We benchmark against strong operational baselines, standard conjunction pipelines and classical maneuver planners. Learning wins on tracking and screening throughput; quantum optimization wins as constellation coordination grows combinatorial. APOGEE routes each job to the method that wins.

Architecture • sensors to spacecraft

One loop, from the ground to orbit.

Observations and telemetry flow up into the catalog; screening and optimization turn them into commands and maneuvers; what the spacecraft actually does flows back to refine every orbit. The loop runs on the ground and, in part, onboard.

Now briefing operators & agencies

Fly a safer constellation.

APOGEE is in early partnerships with satellite operators and space agencies. If you fly assets in a crowded orbit, we will run your catalog through the engine and show you the conjunctions you're not seeing yet.
