Error Modeling and Calibration for Encoded Sun Sensors [PDF]
Sensors, 2013 Error factors in the encoded sun sensor (ESS) are analyzed and simulated. Based on the analysis results, an ESS error compensation model containing structural errors and fine-code algorithm errors is established, and the corresponding calibration method for model parameters is proposed.
