Path: SpacecraftEstimation/AttitudeEstimation
% An attitude determination system using vector measurements. The first column of catalog is the magnetometer data. -------------------------------------------------------------------------- Form: [x, p] = SunMagAttDet( x, p, r, qBToS, bMeas, sensorData, catalog, fScale ) -------------------------------------------------------------------------- ------ Inputs ------ x (3,1) Attitude [x;y;z] p (3,3) State covariance matrix r (m) Measurement noise qBToS (4,1) Quaternion from body to sensor axes bMeas (3,1) Measured magnetic field sensorData (m,3) .xy (2,:) Focal plane data .validMeas (:) 1 if measurement is valid catalog (3,p) Catalog of unit vectors fScale Sensor scale factor ------- Outputs ------- x (3,1) Attitude [x;y;z] p (3,3) State covariance matrix --------------------------------------------------------------------------
