Efficient LOS-Sampled GNSS Direct Position Estimation: An Information-Loss CRB Analysis
Wei Gao, Rong Yang, Jihong Huang +1
Conventional Global Navigation Satellite System (GNSS) Direct Position Estimation (DPE) exploits raw intermediate-frequency (IF) data and provides a full-information Cramér-Rao Bou…
Spatial sparse sampling-based iterative optimization framework for GNSS Direct Position Estimation
Wei Gao, Rong Yang, Jihong Huang +2
Direct position estimation (DPE), a promising technique in Global Navigation Satellite Systems (GNSS) receivers, enables estimation of position, velocity, and time (PVT) solutions…
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…
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…
