New algorithm for attitude and orbit determination using magnetic field measurements

A generalized algorithm for a Combined Nonlinear Control and Estimation CNCE process for spacecraft attitude and orbit determination and control is pre-sented. The approach tends to eliminate the delays due to the separation be-tween the estimation and control processes. Also, it minimizes the possi...
