Abstract In this paper, a method is described for using 8-20MHz noise absorption effect for real time detecting radio wave absorption periods. The method is based on two empirical autoregression models of noise variations. The first (rough) prediction model is based on radar measurements of daily minimum noise variations averaged over 28-days with specially calculated weight coefficients. The second (fine) prediction model uses real-time scaling of rough model. The scaling is based on the compar...

Abstract The Xianshuihe fault is a very large left-lateral strike-slip fault, located on the eastern boundary of the Tibetan Plateau. In the late Cenozoic, this fault played a vital role in accommodating crustal deformation of the eastern Tibetan Plateau. High-spatial-resolution deformation measurements are key to understanding the deformation mechanism (block-like mode or continued mode) and seismic potential of this fault. However, due to the high elevation, harsh field conditions, and dense v...

Abstract In the next 6 years, over 3,000 nano/cubesats launches are expected. This is a segment of the satellite market that has attracted investors’ attention. Recent advances in electronics have led to the miniaturization of components, reduction of power consumption, and significant performance and reliability increase, besides cost reduction. This advance benefited not only the satellite market but also the aerospace sector, in particular for launchers. This work presents a study of the use ...

Abstract The mid- and low-latitude ionosphere is home to a variety of plasma density irregularities, including depletions (bubbles), enhancements (blobs), and small-scale scintillation. Previous studies of plasma density enhancements observed using ROCSAT data have posited that these structures are the direct result of the formation of bubbles near the geomagnetic equator. However, more recent observations from the C/NOFS satellite suggest that multiple mechanisms are responsible for forming pla...

Abstract The Atmospheric Effects of Precipitation through Energetic X-rays (AEPEX) mission is a 6U CubeSat that will monitor energetic electron precipitation from the radiation belts into the upper atmosphere. The primary instrument will image energetic (50–300 keV) X-rays produced in the atmosphere by bremsstrahlung, providing a near-direct signature of electron precipitation. An energetic electron detector will measure the precipitating electron spectrum, while the X-ray observations will be u...

Abstract The Ionospheric Dynamics Exploration and Attitude Subsystem Satellite (IDEASSat / INSPIRESat-2) is a three-unit (U) CubeSat developed with the objective of providing in-situ measurements of the Earth’s ionosphere in order to quantify both global scale ionospheric variability and small scale irregularities. The science payload is the Compact Ionospheric Probe (CIP) - an all in one in-situ plasma sensor developed at Taiwan National Central University (NCU), which is the miniaturized versi...
Abstract The development process of composite structures has suffered from a lack of balance between analysis, design and the use of design methods. This study finds a solution to this matter with an alternative proposal that aims at substituting with a stiffer and lighter material the aluminum alloy originally employed in the construction of the primary structure of a micro satellite (50 kg). The structural components to be substituted are the four vertical lateral walls (VLWs) fabricated as ho...

Abstract China’s Chang’E-4 (CE-4) probe has started its exploration on the far side of the Moon thanks to the relay satellite---Queqiao---which is around the Earth-Moon collinear libration point L 2 and provides continuous communication links between the lander and ground stations. The triangular libration points of the Earth-Moon system, L 4 and L 5 , have long been considered as potential locations for future space applications. As a possible extension of Queqiao or other future missions aroun...

Abstract The interplanetary magnetic field magnitude Bo, proton density Np and solar wind speed Vsw data from Ulysses spacecraft during its interplanetary cruise interval from Earth to Jupiter, from 18 November 1990 to 31 January 1992, are analyzed in this study. Statistical and wavelet techniques are employed to characterize some properties from the solar wind parameters near the ecliptic plane and their dependence with radial distance. The results from kurtosis analysis showed that the three s...
