By the end of 2012, China had launched 16 BeiDou-2 navigation satellites that include six GEOs, five IGSOs and MEOs. This has provided initial precise pointing services ability in Asia-Pacific regions. In order to assess positioning performance system, Wuhan University built up a network BeiDou Experimental Tracking Stations (BETS) around World. The Position Navigation Data Analyst (PANDA) software was modified determine orbits provide orbit satellite clock bias products from system for user...
Soil moisture (SM) data can provide guidance for decision-makers in fields such as drought monitoring and irrigation management. Moisture Active Passive (SMAP) satellite offers sufficient spatial resolution global-scale applications, but its utility is limited regional areas due to lower resolution. To address this issue, study proposed a downscaling framework based on the Stacking strategy. The integrated extreme gradient boosting (XGBoost), light machine (LightGBM), categorical (CatBoost)...
Autonomous driving represents one of the emerging applications that require both high-precision positions and highly critical timeliness to reach stringent safety standards. We develop a method potentially achieve global instantaneous decimeter-level positioning by virtue tightly coupled multi-GNSS triple-frequency observations contributing precise point (PPP). Inter-system phase biases (ISPBs) for two wide-lane observables are first computed each station form inter-GNSS resolvable...
The soil dielectric constant model is essential for retrieving properties based on microwave remote sensing. However, the existing saline models perform poorly in simulating of with high water content and salinity. In this study, Wang Yueru (WYR) model, which was demonstrated to well describing effect salinity moisture constant, validated experimental measurements samples under different degrees. Furthermore, we adjusted form, refitted empirical coefficient finally acquired a two-stage...
Fatigue tests were conducted on 7050-T7451 aluminum alloy, a commonly used material in aircraft, under various stress levels utilizing random load spectrum. The crack extension data statistically analyzed to determine the mean remaining fatigue life and dispersion coefficient for structures with different damage sizes. analysis reveals that of decreases as size increases. At same size, higher result shorter life. Furthermore, increases, difference effect varying diminishes. also increases...
Abstract Sustainability in Cu chemical mechanical polishing (CMP) processing for highly integrated device manufacturing demands electric energy saving and slurry consumption reduction, which can be achieved through faster CMP. A strong chelating agent, quinaldic acid (QA), was chosen to accelerate the rate on an acidic H2O2-BTA system. The complexing capability of QA with ions facilitate formation a porous loose copper oxide film surface H2O2 solution soften microhardness surface, is...
The influence of prefabricated dislocation features induced by rate dependent prestrain on the post-cyclic process in 7075 aluminum alloy exhibits significant variations, which are great importance terms concerns, designs, and discoveries. Considering strain provides diversified hardening stimuli for subsequent cyclic process. maximum stress stage was maintained at same level as prestress with rates ranging from 10-4s−1 to 10-1s−1. Subsequently, adjusting post-cycling amplitude, research...
The Soil Moisture Active Passive (SMAP) satellite makes coincident global measurements of soil moisture using an L-band radar instrument and radiometer. It is crucial to evaluate the errors in newest SMAP satellite-derived products, before they are routinely used scientific research applications. This study represents first evaluation radiometer product over China. In this paper, a preliminary was performed sparse situ from 655 China Meteorological Administration (CMA) monitoring stations...
