Apogee is the flight-proven platform for 6U to ESPA-class smallsats. Bring a payload; we bring the bus, the flight software, and a global ground network. Integrate in weeks. Fly from a browser.
Flying Earth observation, IoT relay, and in-orbit demos for operators on three continents
Stop sourcing avionics from nine vendors and writing flight software from scratch. Apogee ships the bus, the brains, and the ground as a single qualified stack.
A radiation-tolerant compute core with watchdog supervision, triple-redundant boot, and ECC memory. SEU-latchup protected and qualified to TID 30 krad. Your payload talks to it over CAN, SpaceWire, or Ethernet.
Reaction wheels, magnetorquers, a star tracker, and a fused estimator deliver sub-arcminute pointing. Sun-safe and detumble modes are on by default.
MPPT solar regulation, a managed Li-ion pack, and per-rail fault isolation keep the bus alive through every shadow pass.
S-band TT&C and an X-band payload link with AES-256 CCSDS framing and adaptive coding push imagery down at up to 150 Mbps.
Schedule passes, run fault trees, and execute stored command sequences with no human in the loop. The spacecraft flies itself between contacts.
Flight heritage you can underwrite a mission on
Apogee Ground is a global antenna network and a real-time operations console. Schedule passes, watch telemetry stream, and command the spacecraft without standing up your own ground segment.
Book S- and X-band passes across 14 ground stations on five continents, priced per contact with no minimums.
Decommutated, calibrated telemetry streams to your screen in real time, with limit-checking and alerting built in.
Every command is validated against the spacecraft model, dry-run simulated, and logged with full operator attribution.
A flight-faithful simulator mirrors the live vehicle, so you rehearse maneuvers and anomaly responses before they reach orbit.
Three qualified airframes share one avionics core and one software stack, so your payload integration carries forward as you scale.
An 8 kg-class bus for tech demos and IoT relays. Deployable solar, 3-axis control, and a 25 W payload budget in a standard 6U envelope.
A 24 kg-class workhorse for Earth observation. Higher pointing stability, an X-band downlink, and room for a 50 mm-aperture optic.
A 180 kg-class platform with a propulsion bay, 200 W of orbit-average power, and the payload volume for hyperspectral and SAR sensors.
“We went from a payload on a bench to first light in eleven weeks. Building our own bus would have cost us a year and a program.”
“The ground network is the quiet superpower. We commission spacecraft from a laptop instead of leasing antenna time we can't afford.”
“When a wheel saturated on pass three, the autonomy had already safed the bus and queued a desat. We just watched it recover.”
Transparent program pricing. Hardware is fixed-price; ground passes are usage-based with no annual lock-in.
For teams with their own ground segment.
End to end, launch to operations.
For multi-plane fleets and recurring builds.
With a qualified payload, most customers reach first downlink within 90 days of bus delivery. The avionics, software, and ground are already flight-proven, so your schedule is gated by payload integration, not bus development.
Anything that fits the mechanical envelope and power budget: optical and hyperspectral imagers, SAR, RF sensing, IoT relays, and in-orbit demonstration hardware. The integration kit exposes power, data, and thermal interfaces over standard buses.
The baseline bus is engineered to EAR99, and we operate ITAR-aware processes for sensitive payloads. We will work your program through the right licensing path before delivery.
No. The Mission program includes Apogee Ground, but the bus speaks standard CCSDS and works with your existing ground segment or a third-party network if you prefer.
Every bus ships with a compliant deorbit plan. Propulsive platforms can perform a controlled reentry; drag-passive buses meet the 25-year rule by design.
Walk us through your mission in 30 minutes. Leave with a mass, power, and schedule budget mapped to a qualified bus and a launch window.
