Fault Tolerant Attitude Estimation for Small Satellites

Small satellites use commercial off-the-shelf sensors and actuators for attitude determination and control (ADC) to reduce the cost. These sensors and actuators are usually not as robust as the available, more expensive, space-proven equipment. As a result, the ADC system of small satellites is more vulnerable to any fault compared to a system for larger competitors. This book aims at presenting useful solutions for fault-tolerance in ADC systems of small satellites. The contents of the book can be divided into two categories: fault-tolerant attitude filtering algorithms for small satellites and sensor calibration methods to compensate the sensor errors. MATLAB(R) will be used to demonstrate simulations.

• Presents fault-tolerant attitude estimation algorithms for small satellites with an emphasis on algorithms' practicability and applicability
• Incorporates fundamental knowledge about the attitude determination methods at large
• Discusses comprehensive information about attitude sensors for small satellites
• Reviews calibration algorithms for small satellite magnetometers with simulated examples
• Supports theory with MATLAB simulation results which can be easily understood by individuals without a comprehensive background in this field
• Covers up-to-date discussions for small satellite attitude systems design
