... modeled with noise, static bias, misorientation, misleveling, scaling and quantization errors; and the sun sensor is modeled with noise and quantization errors. All sensors are sampled at 10 Hz. Spacecraft disturbance torques ... maximum possible value without leading to numerical instability. The large initial angular error causes GEOB to reach an angular error of almost 100 deg during the first eclipse. However, for the rest ...
... (II.12b), we have \hat \omega \ = \overset\sim \omega - \hat \beta and the estimation error of the angular velocity becomes \delta \omega \ = - (\delta\beta + \eta_\upsilon), where \delta\beta ... nominal quaternion. This implies that the state dimensionality is n = 6.
The conversion from error GRPs to error quaternions is fairly simple and makes use of the sigma points computed in Eqs ...
... I don't know if I ever convinced him. "It was an error."
No, it was not an error, because if we hadn't had the program in there
to fix it, that would have been a bad error.
Fortunately, they had actually experienced this problem…in Houston
