The ISIS Micro Satellite Separation System (M3S) is a three-point microsatellite launch adapter, suitable for a wide range of satellite configurations and sizes. Based on an innovative hold-down and release mechanism design, and building on ISIS’s heritage of its satellite launch adapter family, this system offers a cost-effective solution for the launch of microsatellites as either a primary or secondary payload. Not limited to any size, the M3S system is designed to adapt to the satellite and to the needs of the customer.

  • Designed for satellites of up to 100 kg. Configurations possible for higher masses
  • Deployment induces no shock
  • Low tip-off rates
  • Can be mounted in upright and cantilevered orientation on the launch vehicle
  • Lightweight and cost-effective
  • Electrical and mechanical interface compatible with most common launch vehicles
  • Fly-away part designed for minimum weight and interference


  • Hold-down points can be placed in a diameter that suits the satellite interface
  • Number of hold-down points can be increased to accommodate larger payload masses and sizes
  • Deployment velocity can be adjusted
  • Additional kill-switch and separation switch supports and umbilicals tailored to customer needs
