| titleOfInvention | Simple detector X-ray pulsar navigation timesharing observation method and device |
| abstract | The invention discloses a kind of simple detector X-ray pulsar navigation timesharing observation method and devices, and wherein method includes: acquisition system prior state and system prior state covariance；Estimation System posteriority state covariance is obtained according to the measurement equation of each X-ray pulsar to be observed in presetting database and measurement error estimated value, system prior state and system prior state covariance；System posteriority state covariance calculates the corresponding system mode Posterior estimator error of each X-ray pulsar to be observed on the estimation, to select the smallest X-ray pulsar of system mode Posterior estimator error to be observed；By being observed to obtain the arrival time of X-ray pulsar signal to the smallest X-ray pulsar of system mode Posterior estimator error, to be updated to measured value；And system posteriority state and system posteriority state covariance matrix are obtained according to updated measured value.This method can effectively improve navigation accuracy by timesharing observation. |
