    Load balancing multipath routing protocol for mass remote sensing data downlink in LEO satellite network by Pei-long LIU, Hong-yu CHEN, Song-jie WEI, Hao CHENG, Shuai LI, Jun-yong WANG

    Published 2017-10-01
    “…LEO satellite networks can provide seamless real-time data communication for all kinds of users,which developed rapidly in recent years.At the mean time,the massive payload data down-link system of space data sources,such as remote sensing satellites,still make use of traditional storage and forward mode.The real-time performance of space mission data will be improved effectively,if such satellites are connected to LEO satellite networks equipped with inter satellite links.However,it is necessary to design a specialized satellite network load balancing routing algorithm.Satellite parallel edge-disjoint multipath routing protocol (SPEMR) was designed for remote sensing satellite real-time down-link applications.OPNET simulation results indicate that the performance degradation index(DI) of the multipath scheme implemented by SPEMR is 0.32,which is only 32% of the TLR and 21% of the traditional DSP scheme.It is demonstrated that SPEMR has the better capability of transmitting massive data in real time.…”

    Antenna Configuration Method for RF Measurement Based on DOPs in Satellite Formation Flying by Weiqing Mu, Rongke Liu, Zijie Wang, Yukai Liu

    Published 2018-01-01
    “…Furthermore, the concept of dilution of precision (DOP) is extended to the RF relative measurement sensors, and a new dilution called IDOP is proposed as a benchmark to determine the precision of relative position and attitude measurement in engineering applications of the space mission. In order to select the optimal antenna configuration in real time in a scene where the intersatellite position and attitude change dynamically, this study presents an optimal antenna configuration selection strategy and models the antenna configuration selection as a combinatorial optimization problem. …”

    Cynonyms of the space squad by I. V. Ostroverkhaia

    Published 2025-01-01
    “…The study reveals the main onomastic characteristics of the space squad cynonyms: predominant object-evaluative motivation actualising the dogs-cosmonauts’ external features, behaviour and participation in the space mission; predominance of Russian folk onyms built according to characteristic Russian nominative models; pronounced manifestation of the appellative onymization process resulting in extremely frequent appellative substantives and adjective names formed by direct and associative methods of nomination; presence of transonymization onyms formed in a symbolic way through intercategorial and intraspecific transonymization; prevailing diminutivity, which determines the meliorative evaluation of referents by nominators; memorability explicated through memorial cynonyms with a numerical indicator; presence of single occasional cynonyms, which turn to be a symptomatic manifestation of the nominators’ onomastic creativity; polyonymy due to extralinguistic factors. …”
