Abstract Here we delineate a complete satellite-based augmentation system (SBAS) authentication scheme, including over-the-air rekeying (OTAR), that uses the elliptic curve digital signature algorithm (ECDSA) and timed efficient stream loss-tolerant (TESLA) without quadrature (Q) channel. This scheme appends two new message types to SBAS scheduler over-burdening schedule. We have taken...

Small Baseline Subset InSAR (SBAS InSAR) utilizes a series of synthetic aperture radar (SAR) interferograms to generate time that can analyze the surface displacements coherent points. Still, atmospheric errors in interferometric SAR (InSAR) measurements seriously affect reliability displacement series. In this article, new approach incorporating Generic Atmospheric Correction Online Service fo...

We investigate the structural, electronic and magnetic properties of transition metal (including Mn, Fe, Co, Ni, Cu, Rh Pd) adsorbed on SbAs monolayer by using density functional theory. found that an induced moment is observed for Co atoms, while in case Cu Ni it suppressed local distortions. Our calculations show can induce total spin 4.86μB, 3.51μB, 1.99μB 0.90μB, respectively. The origin ma...

The Laxiwa hydropower station reservoir in the upper reaches of Yellow River basin is located a canyon zone. Due to its complex terrain and difficult transportation, traditional monitoring methods are implement this area, especially during critical deformation stage when personnel may face danger or encounter difficulty reaching site. To achieve long-term continuous dynamic upstream active slop...

Different interferometric approaches have been developed over the past few decades to process SAR data and recover surface deformation, each approach has advantages limitations. Finding an accurate reliable interval for preparing mean deformation rate maps (MDRMs) remains challenging. The primary purpose of this paper is implement application consisting three unsupervised clustering algorithms ...

Interferometric Synthetic Aperture Radar (InSAR) has become the primary remote sensing detection method for monitoring significant surface subsidence and deformation caused by underground coal mining. Time Series InSAR been intensively researched in mining-caused its ability to provide time series, with Small Baseline Subset (SBAS-InSAR) Permanent Scatter (PS-InSAR) being two classical methods....

As a World Cultural Heritage site with sacred landscape featuring an exceptional range of Buddhist art and architecture, much attention has been focused on the sustainable development Bagan (Myanmar). Particularly, monitoring surface subsidence monument instability is great importance to protection planning heritage site. In this study, we applied high resolution TerraSAR-X imagery acquired fro...
