In this study downward longwave (LW) atmospheric radiation data for the period of 2014–2020 were used to search for short-term periodicities using fast Fourier transform (FFT). Several local peaks in the power spectrum density were found and established. The time series exhibits a series of significant peaks (exceeding the 95% confidence limit), such as at 273 days, 227 days, 200 days, 178 days, 157 days

Temporal evolution analysis of storm-enhanced density during an intense magnetic storm on March 2015 Adv. Space Res. (IF 2.177) Pub Date : 2021-01-01 Shiyou Li
An intense Storm Enhancement Density (SED) event with the magnetic storm occurred on 17–24 March 2015 has been investigated. The morphological character of the SED during different phase of the magnetic storm is examined and compared with the non-storm time. Three intensity indexes, i.e., “general” SED index, “heavy” SED index and “severe” SED index, are defined to represent the intensity of SED respectively

Event-Triggered Adaptive Fuzzy Attitude Takeover Control of Spacecraft Adv. Space Res. (IF 2.177) Pub Date : 2020-12-31 Kai Ning; Baolin Wu; Chuang Xu
The problem of attitude takeover control of spacecraft by using cellular satellites with limited communication, actuator faults and input saturation is investigated. In order to lighten the communication burden of cellular satellites, an event-triggered control strategy is adopted. The filtered attitude information needs to be transmitted only when the defined measurement error reaches the event-triggered

Introduction to global short message communication service of BeiDou-3 navigation satellite system Adv. Space Res. (IF 2.177) Pub Date : 2020-12-31 Gang Li; Shuren Guo; Jing Lv; Kanglian Zhao; Zehua He
Short Message Communication (SMC) is a featured service of BeiDou Navigation Satellite System (BDS). After its successful deployment in 2003, Regional Short Message Communication (RSMC) service has been continuously serving China and its neighboring countries and regions, especially in life safety scenarios. In this paper, the architecture of the Global Short Message Communication (GSMC) system is

Analysis of the long lasting events of ionospheric irregularities near the equatorial region of East Asia based on various observations Adv. Space Res. (IF 2.177) Pub Date : 2020-12-31 Sheping Shang; Jiankui Shi; Guojun Wang; Zhengwei Cheng; Zheng Wang; Xiao Wang
Using the ground-based multi instruments observations in Hainan and Southeast Asia, as well as space-based observations, the long lasting events of ionospheric irregularities occurred in the equatorial region of East Asia on the night of March 31, 2014 are studied. Concurrent observations at Hainan station indicate that ionospheric irregularities measured with different instruments showed distinct

Active Vibration Suppression for Flexible Satellites Using a Novel Component Synthesis Method Adv. Space Res. (IF 2.177) Pub Date : 2020-12-30 Liang Zhang; Shijie Xu; Zhiping Zhang; Naigang Cui
This paper is devoted to developing a closed-loop vibration suppression controller for a satellite with large flexible appendages based on component synthesis vibration suppression (CSVS) method. The dynamics model of a flexible satellite is firstly established by using the Newton–Euler methodology, and the dynamics model of the flywheel is also developed. A novel CSVS method is presented based on

Comparative Analysis of Global Optical Observability of Satellites in LEO Adv. Space Res. (IF 2.177) Pub Date : 2020-12-30 L. Shakun; N. Koshkin; E. Korobeynikova; D. Kozhukhov; O. Kozhukhov; S. Strakhova
With a growing number of resident space objects (RSOs), the facilities for near-Earth space surveillance have to cope with increasing workload. It also applies to low-cost small optical surveillance facilities which may present regional, national and global networks. Improved methods of planning and scheduling optical telescopes are required to use these instruments efficiently. Today, optical observations
