GNSS spoofing signals have the same signal structure as authentic signals,so it is difficult to mitigate the spoofing in time and frequency domains,and space domain processing has become one of the mo
It is necessary to measure the real-time rotation speed and the roll angle of a projectile relative to the geodetic coordinate system in order to achieve accurate guidance.To obtain the rotation speed
GNSS spoofing detection method has been widely discussed recently.Most of the detection methods assume that spoofing signal is transmitted by a single source rather than distributed sources.The detect
In this paper,a novel filter based on maximum correntropy criterion(MCC)and M-estimate theory is proposed.The MCC based Kalman filter(MKF)is developed by combining the MCC and the M-estimate theories
To overcome the linearizated errors from the state equation and observation equation based on Extended Kalman Filter(EKF),a Unscented Kalman Filter(UKF)matching algorithm using geomagnetic anomaly bas
GNSS ambiguity fixed solution can greatly improve the accuracy of GNSS/INS integrated system.But it is difficult to achieve perfect real-time dynamic single frequency cycle-slip detection merely by GN
Nowadays,geomagnetic localization has become a new locating method for pedestrian.In this paper,geomagnetic matching localization method is proposed,the result of localization is based on the correlat
In SATCOM On-The-Move(SOTM)systems,an accurate pointing from moving antennas towards the communication satellite is the key to a stable signal tracking.
Smartphone based pedestrian inertial navigation system usually uses the Pedestrian Dead Reckoning(PDR)algorithm to achieve navigation and positioning.The traditional PDR algorithm requires inertial de
