The CubeSat Course is organized into ten distinct modules structured to mirror the real phase-by-phase lifecycle of an orbital space mission—from initial mission design (Phase A) through assembly, testing, integration, launch, and eventual de-orbiting (Phase F).

Pillar 1: Orbital Mechanics & Mission Analysis

Every satellite mission starts with clear orbital geometry and payload requirements. Students learn to model trajectories in Low Earth Orbit (LEO), Sun-Synchronous Orbit (SSO), and Geostationary Transfer Orbits (GTO) using key classical Keplerian Orbit Elements:

Semi-Major Axis : Defines the overall size of the orbit.

Eccentricity : Defines the shape of the orbit (circular vs. elliptical).

Inclination : Defines the tilt of the orbital plane relative to the equator.

Right Ascension of the Ascending Node : Defines the orientation of the orbital plane.

Argument of Perigee : Defines the orientation of the ellipse within the orbital plane.

True Anomaly : Defines the precise position of the satellite along its trajectory at a given time.

Pillar 2: Satellite Architecture & Frame Materials Science

Small satellites operate in unforgiving thermal and structural conditions. The CubeSat Course covers structural engineering standards, load calculations, and advanced materials:

Aluminum 6061-T6: The aerospace gold standard for high strength-to-weight ratio and structural stability.

Bio-Sourced Polymers (e.g., PA11): Innovative lightweight materials used to minimize launch mass by up to 40% while mitigating outgassing under thermal vacuum conditions.

Outgassing Protocols: Selecting materials that do not release volatile organic compounds under a $10^{-5} \ { Torr} vacuum, protecting delicate camera optics and solar cells from contamination.

Pillar 3: Electrical Power Systems (EPS)

A satellite cannot survive without power generation, storage, and precise distribution logic:

Solar Cell Technologies: Integrating high-efficiency triple-junction GaAs (Gallium Arsenide) cells on deployable or body-mounted panels.

Battery Chemistry: Managing Lithium-Ion/Lithium-Iron-Phosphate cell discharge rates during orbit eclipse periods while accounting for extreme temperature variations

Power Distribution Units (PDU): Implementing Maximum Power Point Tracking (MPPT) regulators and over-current protection circuits.

Pillar 4: On-Board Computer (OBC) & Software Architecture

The OBC is the central brain of the spacecraft. The CubeSat Course explores:

Microcontroller vs. FPGA architectures designed for radiation tolerance (Single Event Upset mitigation).

Real-Time Operating Systems (RTOS) like FreeRTOS or cFS (Core Flight System).

Command & Data Handling (C&DH) protocols, telemetry data formatting, and automated fault detection, isolation, and recovery (FDIR).

Pillar 5: Attitude Determination & Control System (ADCS)

Spacecraft pointing accuracy dictates payload success, whether aiming a camera at a city or pointing an antenna at a ground station. The CubeSat Course covers:

Sensors: Magnetometers, Sun sensors, horizon sensors, and miniaturized star trackers.

Actuators: Magnetorquers (for detumbling after release) and 3-axis reaction wheels (for fine pointing adjustments).

Control Algorithms: Proportional-Integral-Derivative (PID) and Extended Kalman Filter (EKF) implementations for accurate state estimation.

Pillar 6: Communications, RF Engineering, & Link Budgets

Connecting ground operators with the satellite requires thorough RF calculation. 

Pillar 7: Payloads & Scientific Instrumentation

Payload design is tailored to specific mission objectives:

Optical Payloads: High-resolution RGB and Multispectral sensors for Earth Observation.

RF Payloads: Automatic Identification System (AIS) receivers for ship tracking and Automatic Dependent Surveillance-Broadcast (ADS-B) for aviation tracking.

Microgravity Experiments: Biological, fluid, or material science tests conducted inside pressurized payload bays.

Pillar 8: Environmental Testing & Thermal Vacuum (TVAC) Validation

Before any satellite is cleared for launch, it must undergo rigorous environmental screening within the framework of the CubeSat Course:

Vibration Testing: Simulating the acoustic and mechanical shock loads of rocket launch profiles (sine sweep and random vibration tests).

Thermal Vacuum (TVAC): Exposing the flight model to extreme cold/hot cycles in a vacuum chamber to induce thermal stress and detect latent material defects.

Pillar 9: Launch Services, Deployers, & Safety Compliance

Integration into the launch vehicle requires strict adherence to launch provider specifications taught throughout the CubeSat Course:

Mechanical Interfaces: Designing according to the standard CubeSat Design Specification (CDS) for compatibility with deployment systems such as P-POD (Poly-Picosatellite Orbital Deployer) or ISIPOD.

Rideshare Logistics: Understanding how small satellites are loaded as secondary payloads alongside larger primary satellites on rockets like the SpaceX Falcon 9 (Transporter missions).

Inhibits & Flight Switches: Wiring mechanical deployment switches to ensure the satellite remains completely unpowered until 30 minutes post-ejection into space.

Pillar 10: Regulatory Licensing, Spectrum Management, & Space Sustainability

Operating in space requires legal and environmental compliance, a major focus area of the CubeSat Course:

International Telecommunication Union (ITU): Filing for radio frequency allocations to prevent signal interference with other satellites.

National Regulators: Navigating national licenses (e.g., FCC in the US, Ofcom in the UK).

Space Debris Mitigation: Ensuring the satellite naturally de-orbits within established international guidelines (e.g., 25-year/5-year rule) using passive drag sails or active propulsion modules.
