Summary
A novel digital sun sensor achieves 1 kHz data rates and 1.1 arcsecond precision over a 105° field of view. This high-performance sensor is crucial for advanced space technologies requiring accurate attitude determination.
Area of Science:
- Space Technology
- Attitude Determination
- Sensor Design
Background:
- Accurate attitude determination is critical for advanced space missions like Earth observation and laser communication.
- Existing sun sensors may not meet the stringent bandwidth and accuracy requirements for these applications.
Purpose of the Study:
- To propose a novel digital sun sensor with high accuracy, a large field of view (FOV), and an ultra-high data update rate.
- To enhance the performance of sun sensors for precise satellite attitude determination.
Main Methods:
- Utilized the Electronic Rolling Shutter (ERS) imaging mode of an APS CMOS detector.
- Introduced an "amplifier factor" to significantly boost the data update rate.
- Developed a novel mask with two aperture patterns, inspired by multiplexing detectors, for high precision and large FOV.
Main Results:
- Achieved an ultra-high data update rate of 1 kHz.
- Demonstrated a precision of 1.1 arcseconds (1σ).
- Covered a large field of view of 105° × 105°.
Conclusions:
- The ERS-based digital sun sensor offers a significant advancement in attitude determination accuracy and speed.
- This sensor technology has broad applications for high-accuracy satellites and future space missions.
