Team Enrollment

ACS

The Attitude Control Subsystem (ACS) is responsible for both sensing and controlling the spacecraft attitude. The team creates a simulation of the spacecraft dynamics and writes the Kalman filter and control software used to steer the satellite.

Structures and Survivability

This team is responsible for designing, analyzing, and manufacturing all mechanical components of the satellite as well as the logistics of the internal components. The are also responsible for analyzing and controlling the satellite's thermal, electrical and vibrational environment on the ground, during launch, and in orbit. Analyses include EMI, atomic oxygen, venting, structural, and thermal.

Systems

The Violet Satellite project employs Systems Engineering extensively. The Systems group is largely responsible for providing the project with direction by creating top level system requirements, creating best practices, maintaining communications, making design choices, and creating processes to ensure a successful product.

Lead: Hunter Adams - vha3 (@cornell.edu)

Telemetry and Communications

T+C is responsible for satellite to ground communications. T+C uses modified commercial radios operating in amateur frequency bands to transmit and receive data and commands between the satellite and the ground stations.
