Star Pattern Recognition for Attitude Determination Using Genetic Algorithms
This paper presents a study using Genetic Algorithms (GA) to solve the star pattern recognition problem associated with star tracker attitude determination systems. Characteristics of the stars that are visible within the Field of View (FOV) of an imager are defined with regard to relative distances and angles. The proposed GA minimizes the discrepancy between the characteristics of the stars i...
متن کاملA High Performance Star Sensor System for Full Attitude Determination on a Microsatellite
ABSTRACT A high precision star sensor system is presented for accurate attitude determination on the SUNSAT microsatellite. The design constraints were low cost, mass, volume and power. The principle of operation is to image stars and match the observed constellation to a star catalogue. A set of corresponding observed and reference vectors are used to feed an extended Kalman filter for full at...

متن کاملA Novel Attitude Determination System Aided by Polarization Sensor
This paper aims to develop a novel attitude determination system aided by polarization sensor. An improved heading angle function is derived using the perpendicular relationship between directions of E-vector of linearly polarized light and solar vector in the atmospheric polarization distribution model. The Extended Kalman filter (EKF) with quaternion differential equation as a dynamic model i...
متن کاملA Pinhole Sun Sensor for Balloon-borne Experiment Attitude Determination
We report on the design, calibration and in-flight performance of a sun sensor, which is used to determine the attitude of a balloon-borne telescope. The device uses a position-sensitive detector (PSD) in a pinhole camera. By determining the position of the image of the Sun on the PSD, the orientation of the sun sensor and the boresight of the telescope relative to the Sun can be determined. Th...
