Executive Summary
This thesis details the design and simulation of an attitude determination system for a tactically useful Earth-imaging nano-satellite, specifically the TINYSCOPE project. It focuses on sensor selection, characterization, and high-fidelity simulation using an Extended Kalman Filter for multi-rate sensors. The goal is to enable low-cost, operationally responsive space capabilities for tactical imagery.
Why It Matters
This document is crucial for defense analysts interested in the development of low-cost, tactically relevant space assets, as it details the technical foundation for small satellite imagery capabilities. It highlights advancements in miniaturized satellite technology that can enhance military intelligence and operational responsiveness.
Key Takeaways
- The thesis develops a detailed attitude determination system design for a tactical Earth-imaging nano-satellite (TINYSCOPE) based on the CubeSat standard.
- It utilizes an Extended Kalman Filter with multiple sensor types (star tracker, sun sensor, gyroscope, magnetometer) for high-fidelity attitude determination.
- The research aims to enable operationally responsive space capabilities, providing useful tactical-level imagery products from small, inexpensive satellites.
Strategic Relevance
The development of low-cost, tactically useful nano-satellites for Earth imaging significantly enhances military intelligence, surveillance, and reconnaissance (ISR) capabilities. This technology supports operationally responsive space, allowing for rapid deployment and persistent coverage, which is critical for tactical decision-making and reducing reliance on larger, more expensive satellite systems.
