Optimal Walker Constellation Design of LEO-Based Global Navigation and Augmentation System
TL;DR: This paper designs a LEO-based optimal global navigation and augmentation constellations designed by a non-dominated sorting genetic algorithm III (NSGA-III) and genetic algorithm (GA) and proves that the computation efficiency of the constellation design can be considerably improved by using master–slave parallel computing.

Dirichlet Process Mixtures for Density Estimation in Dynamic Nonlinear Modeling: Application to GPS Positioning in Urban Canyons
TL;DR: An attractive flexible Bayesian nonparametric noise model based on Dirichlet process mixtures (DPM) is introduced and the suitability of the proposed modeling scheme in a joint state/parameter estimation problem is handled by an efficient Rao-Blackwellized particle filter (RBPF).

Detecting the Orbital Angular Momentum of Electro-Magnetic Waves Using Virtual Rotational Antenna.
Chao Zhang,Lu Ma +1 more
TL;DR: An OAM mode detection method based on digitally rotating a virtual antenna, where the transmitter and receiver are physically fixed, but the Virtual Rotational Antenna is obtained by interpolating the signals received from transverse-mounted receiving antennas.
Temporal Characteristics of GPS Error Sources and Their Impact on Relative Positioning
TL;DR: In this research, the temporal characteristics of the orbital, satellite clock, and ionospheric errors are analyzed independently and the effect of each error in the position domain is investigated in addition to the combined effect.

A Novel Approach in Detection and Characterization of CW Interference of GPS Signal Using Receiver Estimation of C/No
TL;DR: Using the post- processing capability of a software GPS receiver, CW interference is detected and characterized by passing the GPS signal and the interference through the correlator, and the existence and characterization of the existing interference is determined.
