Abstract

This research studies, analyzes, and develops the extended  Kalman filter algorithm to increase its accuracy in estimating the attitude  of a  CUBESAT with a size of 1U and dimensions of  10 * 10 * 10 cm^3 at a low altitude of 600 km and a weight of  1.33 kg. This research also shows the components of the control system for the stability of the cubic satellite and its mechanism of action,  Simulations were made for the control and  attitude estimation systems using the MATLAB/R2020a environment. The nature of the orbit within which the cubic satellite moves is circular.

This research demonstrated the effectiveness of the developed EDEKF attitude  estimation algorithm in increasing the position  accuracy of the  CUBESAT by 2.79 times over the EKF filter, with an improvement rate of 64.1%.  It also contributed to increasing the stability of the CUBESAT  on orbit by 1.73 times, with an average error of 0.01%. The EDEKF algorithm was also able to reduce the settling time of the CUBESAT in orbit to a value of 130.65 minutes, which is approximately 1.52 times that of the EKF filter.
