To ensure reliability and accuracy in the Global Navigation Satellite Systems (GNSS) real-time data streams, maintenance operations may be performed at the server side, which could temporarily interrupt the availability of the real-time products for users. To address these issues, backup products were introduced by Centre National d’Etudes Spatiales Navigation Team (CNES/Nav) in November 2022. Du…

Windows are critical components for maintaining the functionality of space stations in the demanding environment of Low Earth Orbit (LEO). This article considers borosilicate glass (BSG) as a compelling novel material for multi-pane fenestration, evaluating its potential to outperform traditional options like fused silica (FS). By specializing our previously-established methodological framework, …

Solar flares are sudden, violent events that occur in the sun’s atmosphere and release large amounts of radiation. These phenomena can impact technological systems on Earth and in orbit, causing financial losses and endangering human life. Thus, forecasting these flares is crucial to mitigating their effects. Solar activity is monitored using specialized instruments that provide data for machine …

• this study proposes a novel ZHD model (NZHD) that requires input of surface atmospheric pressure and water vapor pressure. • To address the challenge of obtaining real-time meteorological observations, we constructed a high-resolution grid model of atmospheric pressure and water vapor pressure for the Chinese region based on real-time meteorological observations. • Compared to traditional model…

This paper investigates the effects of geomagnetic disturbances that occurred in August 2017, during the declining phase of Solar Cycle 24, when two geomagnetic storms driven by high-speed stream (HSS) and stream interaction region (SIR) structures and associated with HILDCAA intervals took place on 4–6 August and 17–21 August, together with a coronal mass ejection (CME) embedded in the solar win…
