Logistic-aided Huber M-estimator for robust GNSS positioning
Zhengdao Li, Penggao Yan, Li-Ta Hsu
This paper develops a logistic-aided Huber (LAH) M-estimator for robust GNSS positioning under long-tailed, multipath-affected measurement errors. The key idea is to leverage a log…

Improved GNSS Positioning in Urban Environments Using a Logistic Error Model
Zhengdao Li, Penggao Yan, Baoshan Song +1
A Gaussian error assumption is commonly adopted in the pseudorange measurement model for global navigation satellite system (GNSS) positioning, which leads to the conventional leas…
