ADCNS

The Attitude Determination, Control, and Navigation Subsystem (ADCNS) executes the relative navigation that will be used for CUSat's in-orbit inspection procedures. CUSat will primarily be using three GPS boards for attitude determination. For attitude control, CUSat will be using pulsed-plasma thrusters (PPTs) and torque coils. The software portion of ADCNS will consist of the relative navigation algorithms, which will run the various modes of operation defined by the CONOPs.

Camera

The camera team is responsible for acquiring images while in orbit, compressing them in a modified JPEG format, and relaying them to the onboard computer, C&DH.

Command and Data Handling

C&DH is the central hub for communication and computation on the satellite. Using a commercial off the shelf (COTS) single board computer running Windows CE and C++, C&DH will execute the ADCNS algorithms and flight code.

Design Trade Study 1

Design Trade Study 1 was a technical analysis with respect to the design of having a Dawgstar satellite inspect a cubesat, which would launch inside the satellite and be ejected from within once in-orbit.

GPS

The GPS team is responsible for the GPS receivers, antennas and algorithms used to calculate sub-centimeter relative positioning.

Design Trade Study 2

Design Trade Study 2 was a technical analysis with respect to the design of having two identical satellite shapes, which would launch together and then separate. This design study resulted in the concept of the current CUSat design.

Ground Segment

The Ground Segment is responsible for the ground operations of the satellite, including ground to satellite communication, tracking and commanding.

Survivability

The Survivability team is responsible for analyzing and controlling the satellite's thermal, electrical and vibrational environment on the ground, during launch, and in orbit. Analyzed effects include ESD, atomic oxygen effects, venting and outgassing.

Systems

The CUSat 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 for creating a successful product. Each of the subsystem leads also participates as a member of the Systems group, which allows the project to maintain consistency and focus.

Telemetry and Command

T&C is responsible for intersatellite communications as well as satellite to ground communications. T&C uses modified commercial radios operating in amateur frequency bands to transmit images taken by the satellites to the ground station.

Mission Ops

The Mission Ops team defines the detailed, on orbit operations plan for both CUSat satellites. Operating procedures are defined to match with hardware and mission specifications and help ensure successful execution of the mission.

Electrical Hardware

The Electrical Hardware team manufactures and manages the design of all the electronics on the spacecraft. Each satellite contains nine custom design PCB (printed circuit boards). This team also manufactures the wiring harness for the satellite electronics.

Mechanical Hardware

The Mechanical Hardware team manufactures the satellite structure and manages the design. The structure includes eight isogrid panels as well as numerous electronics board enclosures. This team also develops the Pulsed-Plasma Thrusters (PPTs) that are used for attitude and position control.

Ground Segment

The Ground Segment team ensures proper implementation of CUSat ground operations. This includes building and coordinaing the four ground stations (Ithaca, Redondo Beach, Colorado Springs, and Kwaj) as well as implementing software that allows for easy control and communication with both satellites.
