Credible Uncertainty Quantification under Noise and System Model Mismatch
Penggao Yan, Xingqun Zhan, Rui Sun +1
State estimators often provide self-assessed uncertainty metrics, such as covariance matrices, whose credibility is critical for downstream tasks. However, these self-assessments c…

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…
