SF-12 is built around a standard deployer and a common avionics core, so a small payload can fly without a one-off bus.

Small spacecraft still carry a complete mission. Deployable structure, electrical power, heat rejection, pointing, and the payload data path must share a tightly constrained volume. The SF-12 discussion starts with the instrument and the rideshare interface, then works outward to the spacecraft that supports them.

  • Deployer fit

    The mechanical design follows standard deployer interfaces.

  • Common avionics

    Foundry Edge is the flight software shared across the SF family.

  • Repeatable build

    Assembly and test are set up for more than a single spacecraft.

Bus family

Four buses, by class.

  1. SF-12Rideshare
  2. SF-150ESPA-class
  3. SF-500Microsat
  4. SF-GEOGEO-class
