| Description |
Under the project NPMICAV, two estimation algorithms namely, 15-state EKF and NCF-EKF
spilt architecture are developed and evaluated in software-in-the-loop simulation (SILS) environment for
estimating position, velocities, attitude and heading of ‘Black-Kite’ MAV. The performance of both the
estimators is observed to be satisfactory. 100 Monte Carlo simulations were performed on both the
estimators and root mean square error (RMSE) of the estimates is found to be within 1-σ bound thereby
indicating their robustness against the measurement noise. The 15-state EKF is reduced to 4-state EKF
in quaternion form and NCF-EKF split algorithm is reduced to NCF and are implemented successfully
on APM-2.5 board. The performance of 4-state EKF and NCF is evaluated using LAB test,
Processor-in-the-loop simulation (PILS) and flight data. From these evaluations it is found that under no
wind condition 4-state EKF and NCF are comparable with the reference. But the performance of 4-state
EKF estimator degrades in windy conditions when compared to the reference. On indigenously
developed NAL auto-pilot board, 4-state EKF is implemented and some ground tests and flight test are
carried out. Initial results look encouraging however there are some issues such as code optimization,
data logging etc that need to be resolved in order to provide attitude and heading at the rate of 50 Hz
