Journal ArticleDOI
On the computation and approximation of ultra-high-degree spherical harmonic series
TL;DR: In this paper, it was shown that in the degree-and-order domain, (l,m) of these functions (with full ortho-normalization), their rather stable oscillatory behavior is distinctly separated from a region of very strong attenuation by a simple linear relationship: m = \ell \sin \theta\), where θ is the polar angle.
Journal ArticleDOI
Network-based Collaborative Navigation in GPS-Denied Environment
TL;DR: In this paper, three statistical network-based collaborative navigation algorithms, the Restricted Least Squares Solution (RLESS), the Stochastic Constrained Least-Squares (SCLESS), and the Best Linear Minimum Partial Bias Estimation (BLIMPBE) are proposed and compared to the Kalman filter.
Journal ArticleDOI
Neural Network Aided Adaptive Filtering and Smoothing for an Integrated INS/GPS Unexploded Ordnance Geolocation System
Jong-Ki Lee,Christopher Jekeli +1 more
TL;DR: In this paper, the authors compared the improvement in the geolocation accuracy when the neural network approach is applied to aid the adaptive versions of the extended Kalman filter (EKF) and the unscented Kalman Filter (UKF).
Journal ArticleDOI
Cart-Mounted Geolocation System for Unexploded Ordnance With Adaptive ZUPT Assistance
Leilei Li,Yingjun Pan,Jong-Ki Lee,Chunhua Ren,Yu Liu,Dorota A. Grejner-Brzezinska,Charles K. Toth +6 more
TL;DR: An adaptive ZUPT (AZUPT) algorithm in a sliding time window is proposed to guarantee the correct identification of the zero velocity condition and improve the position accuracy of UXO geolocation.
Journal ArticleDOI
Modeling errors in upward continuation for INS gravity compensation
TL;DR: In this paper, an analysis of the model errors in upward continuation using derivatives of the standard Pizzetti integral solution (spherical approximation) shows that discretization of the data and truncation of the integral are the major sources of error in the predicted horizontal components of the gravity disturbance.
