Attitude Anomaly Tracking Software

SWITCH TO API

Description

The Attitude Anomaly tracking software is designed to predict deviations in a system’s orientation, crucial for stability. It scrutinizes data from various sensors like Accelerometers and |Gyroscopes to discern anomalies from expected behavior. When anomalies arise, the sensor triggers alerts or corrective actions, safeguarding against malfunctions. Its design demands precision in sensor fusion, noise reduction, and adaptability to diverse conditions. Ultimately, this sensor stands as a vigilant guardian, enhancing system reliability by foreseeing and mitigating abnormal attitudes.

Example Use Cases

• Sensor Platform: The sensor platform scenario houses a collective of sensors and the attitude anomaly sensor used the IMU to predict this, on a Spacecraft.

---

Module Implementation

The attitude anomaly detector functions solely on the comparison of the sensors to the state of the spacecraft. In terms of the IMU sensor, the detector compares the angular velocity detected by the sensor and the state of the spacecraft using the navigator as follows:

$$\begin{array}{c}{\mathrm{IMU}}_{\mathrm{failure}}=\{\begin{array}{ll}\mathrm{true},& \text{if }|{\dot{\omega }}_{\mathrm{IMU}}-{\dot{\omega }}_{\mathrm{nav}}|>\mathrm{threshhold}\\ \mathrm{false},& \text{otherwise}\end{array}\end{array}$$

Where $\dot{\omega }$ is the angular velocity.

Assumptions/Limitations

• Accelerometers or gyroscopes is the only sensor active for verification on the attitude anomaly detector
• Functionality and accuracy are solely dependent on that of the Navigator
