Geometrical portrait of Multipath error propagation in GNSS Direct Position Estimation
Jihong Huang, Rong Yang, Wei Gao +2
Direct Position Estimation (DPE) is a method that directly estimate position, velocity, and time (PVT) information from cross ambiguity function (CAF) of the GNSS signals, signific…

An Accelerated Camera 3DMA Framework for Efficient Urban GNSS Multipath Estimation
Shiyao Lv, Xin Zhang, Xingqun Zhan
Robust GNSS positioning in urban environments is still plagued by multipath effects, particularly due to the complex signal propagation induced by ubiquitous surfaces with varied r…

Weiss-Weinstein bound of frequency estimation error for very weak GNSS signals
Xin Zhang, Xingqun Zhan, Jihong Huang +2
Tightness remains the center quest in all modern estimation bounds. For very weak signals, this is made possible with judicial choices of prior probability distribution and bound f…
