## Project Stratosphere: Mission Title
* **Institution**: Gower College Swansea & University of South Wales.
* **Objective**: Design and simulation of a sustainable 1U CubeSat for monitoring the ozone layer above Wales.
* **Budget**: £200 limit (Estimated spend: £88.30).

## Mission Definition & Parameters
* **Target Altitude**: 10–20 km via high-altitude balloon.
* **Environmental Conditions**: Withstanding temperatures from -40°C to -50°C.
* **Scientific Payload**: Monitoring ozone concentration (0–10 ppm), UV radiation, temperature, and pressure.

## System Design: Electronics
* **Microcontroller**: Seeeduino Lotus Cortex-M0+ (ATSAMD21).
* **Primary Sensor**: DFRobot Gravity Ozone Sensor (10 ppb resolution).
* **Navigation**: Grove GPS Air530 Module (50 km ceiling).
* **Power**: 3.7V 2Ah LiPo battery with chemical heat pack management.

## Structural & Thermal Management
* **Frame**: Aluminium 6061-T6 alloy for high strength-to-weight ratio.
* **Insulation**: EPP foam and Mylar blanket to maintain internal temperature >0°C.
* **Dimensions**: 1U format (10x10x10 cm).

## Cost Analysis
* **Ozone Sensor**: £43.08
* **LiPo Battery**: £22.10
* **GPS Module**: £11.77
* **Total Estimated Cost**: £88.30 (approx. 56% budget remaining).

## Future Recommendations
* **Telemetry**: Integration of LoRa radio for real-time data.
* **Sensors**: Addition of CO2 and Methane (CH4) gas sensors.
* **Imaging**: Implementation of an HD camera for visual verification.
