What We Build
CubeSats and TubeSats, built in South Africa.
EAK-Orbitals designs and manufactures small satellites for Earth observation and scientific research.
CubeSats
Standard 1U–6U CubeSat buses for Earth observation and hosted scientific payloads.
TubeSats
Cylindrical 1U TubeSat buses — our lowest-cost route to orbit, flown as Sustaino-1.
Bespoke missions
We specialise in CubeSats and TubeSats, but we can engineer to almost any mission brief.
Latest Mission Updates
Building in public — 17 hours a day, 7 days a week.
This month
Solar panel & flight computer subsystem integration under way.
Upcoming
Ground station RF chain and LoRa link budget verification.
Certified Sustainable
South Africa's first sustainable satellite.
EAK-Orbitals is certified by SACSIC — the South African Council for Sustainable Infrastructure and Communities.
Awarded the Certificate of Sustainability by SACSIC for being South Africa's only sustainable satellite manufacturing company, pursuing a cleaner and more sustainable future from space and from land.

Capabilities Matrix
Eighty capabilities across the programme.
From onboard autonomy to commercial data delivery — what EAK-Orbitals brings to a mission.
- 01Infrared mineral prospecting
Shortwave-infrared spectral signatures reveal surface mineralogy for exploration targeting.
- 02Live imagery tasking
Commercial clients can request passes over a defined area of interest.
- 03Sun-synchronous coverage
Consistent local solar time means comparable imagery, pass after pass.
- 04Edge-AI onboard processing
Frames are triaged in orbit so only useful data consumes downlink.
- 05LoRa 434 MHz downlink
Low-power, long-range telemetry proven on our own ground segment.
- 06UHF beacon
Independent health beacon receivable by amateur stations worldwide.
- 07EAK-GS1 ground station
Motorised az/el Yagi array in Johannesburg with Doppler correction.
- 08Redundant flight computer
ARM Cortex-M4 flight computer with watchdog supervision and safe-mode fallback.
- 09Body-mounted GaAs solar
High-efficiency cells across every facet of the TubeSat bus.
- 10Li-Po energy buffer
Sized for full eclipse operations plus imaging peaks.
- 11Passive thermal design
No moving parts, no fluid loops — survivable across orbital extremes.
- 12Radiation-tolerant layout
Shielded avionics ring and error-corrected memory scrubbing.
Intellectual Property
All designs and camera technology are patented.
EAK-Orbitals has patented its satellite designs and its imaging camera system. The bus architecture, spectral payload and associated processing may not be reproduced, manufactured or commercially exploited without a written licence from EAK-Orbitals (Pty) Ltd.
Quote of the Week
“Great spirits have always encountered violent opposition from mediocre minds.”
Future Missions
A roadmap, not a single shot.
- 🟢2027Sustaino-1 · Debut 1U TubeSat
