海军护航打击索马里海盗有充分的国际法依据。《联合国海洋法公约》关于海盗行为的定义一定程度上限制了对索马里海盗的打击。短时间内,修订《联合国海洋法公约》关于海盗的定义并不现实,联合国安理会的决议又具有临时性,通过双边或区域协议的方式对海盗的认定达成共识是一种可行的方法。由某一主权国家审判索马里海盗存在一定的困难性,国际社会可采取特设法庭的方式来审判索马里海盗。我国应制定惩治海盗的国内法。

PRIS: A Novel Complex Sequence Construction Method

第五届中国卫星导航学术年会

作者： Zuping Tang Jiaolong Wei Hongwei Zhou Tao Yan Zhihui Zhou bo qu Huazhong University of Science & Technology Beijing Institute of Tracking and Telecommunication Technology

Unexceptionally, modern global Navigation Satellite System （GNSS） adopt Direct Sequence Spread Spectrum （DSSS） signal structure, in which, correlation property of Pseudo Random Noise（PRN） code play an important role of affecting its rejection performance to Narrow Band Interference（NBI） and Multiple Address Interference （MAI）. In order to mitigate the cross‐correlation performance degradation due to tiered code construction, this paper proposes a new method for constructing complex sequence of GNSS civil signal. Based on any primary sequence of length L, Pseudo Random Initiate State （PRIS） transformation is used to construct a complex sequence of length NL, and a feasible generator scheme is presented. Simulation and analysis results shows, the acquisition complexity of PRIS sequence is similar to tiered code, and the correlation property of PRIS sequence is 4‐5dB better than tiered code, which approaches the performance of random sequence of length NL. The proposed method is applicable to civil GNSS signal designing, and is helpful to improve the receiving performance in challenge environment without distinct additional complexity, which will be attractive to GNSS users around the world.

LEO navigation augmentation system has become an inevitable choice and development direction to meet the urgent requirements of higher precision, higher reliability and higher security PNT in emerging satellite navigation applications. Therefore, the compatibility between LEO navigation augmentation signal and GNSS signal has become a problem to be solved, the compatibility design requirements of LEO navigation augmentation signals and GNSS signals are mainly reflected in two aspects:1. Reasonable compatibility design can make traditional GNSS receivers suitable for LEO navigation augmentation system through a small number of system upgrades, which expands the service scope of the system and improves the service quality;2. Systematic compatibility design needs to cover on-board transceiver isolation technology, reduce the complexity of payload co frequency integration and improve system reliability. In this paper, LEO navigation augmentation compatible signal is studied from two perspectives of ground user and payload realization respectively, and the chip level pulse quasi-continuous navigation signal CPQC-NAV is optimized, which is studied in time domain, frequency domain and correlation domain. On this base, we design receiver algorithm for payload and ground user, and the performance of navigation system is theoretically analyzed. The accuracy of theoretical analysis is verified by simulation test and the feasibility of system design is verified by hardware platform. Results show that *** receiver of chip level pulse quasi-continuous navigation signal has good compatibility with GNSS, CPQC-NAV shows pluse characteristics in time domain and continuity in measurement domain, which has no impact on the augmentation service of LEO navigation. 2. With CPQC-NAV, the problem of the COfrequency transceiver of the satellite payload has been effectively solved.

The performance assessment on lunar navigation for GNSS

第九届中国卫星导航学术年会

作者： bo qu Tao Yan Xingyuan Han Yanguang Wang Longlong Li Yansong Meng China Academy of Space Technology(Xi’an)

With the gradual implementation of China’s lunar exploration project, the ground monitoring and control network also has to complete a large number of lunar monitoring and control tasks. In order to alleviate this pressure, lunar spacecraft needs to employ other methods to finish its positioning and timing tasks. Global navigation satellite system is designed to provide positioning and timing service for terrestrial users. Because of the improvement on GNSS receiver, it has been used on LEO satellites and spacecraft. However, the signal power of navigation satellites in GNSS is weak, and GDOP of visible satellites is bad, which is a big challenge for the design of GNSS receiver on lunar orbit. In this paper, the lunar navigation performance of GPS and BDS Ⅲ is evaluated. We analyzed the propagation attenuation loss of GPS and BDS Ⅲ signals on the moon, and gave the propagation attenuation of these signals at different frequencies. In addition, we investigated the power variation characteristic, the number variation, visible time, and GDOP of navigation satellites in GPS and BDS, which can improve the design of GNSS receiver for lunar mission.

秦汉时雇佣的记载颇多。居延、敦煌所出汉简中的"庸券",经考证乃是书写于中原内地各郡,由庸者代雇者服戍役时带到边地的雇佣券实物,是汉代更戍制度中流行的践更制的具体体现。"僦券"则多书写于边地,是对车牛等物及其主人的一种短雇。这些均是公元前后,即西汉到东汉的雇佣券。对汉简中这批雇佣文契的首次认定,改变了传统认为雇佣券最早是十六国时期的看法,比传统认为的最早雇佣券提前了三、四百年。
