CubeSat

A standardized small satellite format using 10cm cubic units (1U = 10×10×10 cm), enabling cost-effective space access.

CubeSats are miniaturized satellites built to standard dimensions, revolutionizing access to space for universities, startups, and developing nations.

Standard Sizes

  • 1U: 10×10×10 cm (~1-2 kg)
  • 2U: 10×10×20 cm (~2-4 kg)
  • 3U: 10×10×30 cm (~3-6 kg)
  • 6U: 10×20×30 cm (~6-12 kg)
  • 12U: 20×20×30 cm (~12-24 kg)

Regulatory Status CubeSats typically qualify for:

  • Light regime authorization (EU Space Act)
  • Simplified licensing procedures
  • Reduced insurance requirements
  • Academic exemptions (in some jurisdictions)

Debris Considerations Despite small size, CubeSats must:

  • Comply with debris mitigation guidelines
  • Ensure timely deorbit (< 5 years under EU rules)
  • Consider deployable drag devices
  • Avoid trackability concerns

Deployment Methods

  • ISS deployment (JAXA, NanoRacks)
  • Dedicated small satellite launchers
  • Rideshare on larger missions
  • Orbital transfer vehicles

Capabilities Modern CubeSats can perform:

  • Earth observation
  • Communications relay
  • Technology demonstration
  • Scientific research
  • IoT connectivity
