ABSTRACT The United States (U.S.) faces challenges in achieving its ambitious net‐zero carbon emissions target by 2050, with current emissions having fallen by less than 1% in 2024. Despite an investment of $500 billion in low‐carbon resources while holding the second‐largest green technology patent portfolio globally, it is further imperative to ...

Real-time PPP-based monitoring of Galileo–BDS time offset using PPP-B2b and HAS
Abstract In multi-GNSS positioning, navigation and timing, the inter-system time offset must be handled explicitly. For Galileo–BDS Time Offset (GBTO), PPP-BCE is limited by signal-in-space errors, and fixing GBTO as a prior is fragile due to sub-nanosecond datum and inter-system bias drifts between HAS (GTRF) and

Real-Time Estimation of Ionospheric Power Spectral Density for Enhanced BDS PPP/PPP-AR Performance
The undifferenced and uncombined (UDUC) model preserves raw code and carrier-phase observations for each frequency, avoiding differencing or ionosphere-free combinations. This approach enables the direct estimation of atmospheric parameters. However, the stochastic characteristics of these parameters, particularly ionospheric delay, are often ...
