What you get.

Segal Aerospace

Power, data, and the payload interface are designed together, so the instrument and the bus are one spacecraft.

The payload defines the platform: what it observes, how steadily it must point, and how much information must reach the ground. Mechanical, electrical, thermal, and data interfaces belong in the same design conversation, together with the orbit, operating life, and plan for the end of the mission.

  • Payload interface

    Mechanical, power, and data interfaces are common across payloads.

  • Onboard processing

    Collection and downlink are planned with the compute on the spacecraft.

  • Orbit keeping

    Propulsion is part of the design for station-keeping and disposal.
