Analysis on the coverage performance and networking scheme of an MEO constellation by Yanbin ZHAO, Renning WANG, Peipei HU

“…Geostationary earth orbit (GEO) satellite orbit position resources have been scarce for a long time.The development of giant low-orbit satellite constellations has made the low-orbit resources unprecedentedly scarce.As a compromise between GEO and low earth orbit (LEO) constellations, the medium earth orbit (MEO) constellation will surely become a battle field for all countries.Referring to various MEO constellations in the world and our national conditions, a (6+4) MEO constellation was proposed.STK (Satellite Tool Kit) was used to simulate and analyze the constellation coverage performance, inter-satellite link characteristics, gateway site selection and coverage performance.Inter-orbit communication was realized through ground station relay, effectively avoiding various problems through inter-satellite links.The system was more simple and steady.It's much valuable in strategy in the circumstance of global low-orbit resources scarce.…”

Design of amplifying information metasurface for enhancing signal coverage by Lijie WU, Hanqing YANG, Qiang CHENG, Tiejun CUI

“…Traditional information metasurfaces can be used in wireless relay systems to control the propagation direction of electromagnetic waves due to their capability to control the amplitude and phase.However, owing to the lack of signal amplification function, these metasurfaces have a limited operating distance.Thus, a large size of metasurfaces is usually demanded to realize the signal coverage of dead zones.To solve this problem, an amplifying information metasurface was designed to realize the 2 bit phase manipulation and signal amplification function within the broad band from 2.7 to 3.1 GHz.Furthermore, a power dividing and combining network was introduced to combine the 1×8 metasurface elements into an array with only one amplifier, which greatly reduced the number of amplifiers, the hardware cost, and the power consumption.The simulation results indicate that the array can realize beamforming and signal amplification over a broad band.Therefore, the proposed amplifying information metasurface array may find important applications in wireless relay systems and provide a new solution to enhancing the signal coverage and reducing the size of the metasurface array.…”
