Estimation of BDS pseudorange biases with high temporal resolution: feasibility, affecting factors, and necessity

open access: yesSatellite Navigation, 2023
A common practice adopted for the pseudorange bias estimation and calibration assumes that Global Navigation Satellite System satellite-dependent pseudorange biases vary gently over time. Whereupon satellite pseudorange biases are routinely estimated and

A time‐stamp calibration method for smart meter data based on interpolated least squares

open access: yesEnergy Conversion and Economics, EarlyView.
Abstract Temporal asynchrony in smart meter data, caused by clock drift and protocol failures, significantly undermines grid state estimation and fault location. Traditional synchronization methods often rely on costly hardware or real‐time protocols and are ineffective for historical data and legacy devices.

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...
