In December 2017, China Satellite Navigation Office published the open service signal B2a transmitted from the BDS space segment to the BDS user segment. The B2a signal is transmitted by the Medium Earth Orbit (MEO) satellites and the Inclined Geosynchronous Satellite Orbit (IGSO) satellites of BDS-3, and provides open services. When the signal is transmitted to the ground, it can be reflected or scattered into the receiver through the ground object. This phenomenon is called multipath. The multipath signal will be attached to the direct signal, and that causes the autocorrelation function to be distorted which causes the error of measuring at the end. This paper introduces the characteristics of B2a signal briefly at first, and then analyzes the Narrow Correlator Spacing Technique, the Early/Late Slope Technique (ELS), the Double-Delta Correlator Technique, and the Code Correlation Reference Waveform Technique (CCRW) for B2a signal. The simulation results show that the W4 waveform of CCRW is the best for the multipath mitigation for B2a signal, and the multipath error envelope is reduced by 67.31% compared with the Narrow Correlator Technique with the infinite bandwidth.","PeriodicalId":434266,"journal":{"name":"2018 European Navigation Conference (ENC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124006881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike classical GNSS point positioning, which uses the pseudorange observables from four or more visible satellites and the broadcast ephemeris to obtain the user instantaneous position, PPP takes the advantage of the more precise carrier phase measurements, attempting to account for all the GNSS errors and biases. PPP is able to provide accuracy level comparable to differential positioning. In particular, the single-frequency (SF) PPP technique is attracting great interest, since SF GNSS devices are widely used for most positioning and navigation applications. For this aim, the paper proposes a SF-PPP approach based on the use of code and single-frequency ionosphere-free linear observables combination, collected from GPS and Galileo systems. In addition, an integrity monitoring algorithm is modified to be applied to SF-PPP for the detection, isolation and the removal of faulty measurement sources. The proposed strategy is tested using real and simulated data gathered in static mode. Results demonstrate the effectiveness of the proposed integrity monitoring algorithm, applied to SF-PPP.","PeriodicalId":434266,"journal":{"name":"2018 European Navigation Conference (ENC)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122548091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The LEO satellites can serve both as space-based monitoring stations and as navigation information broadcasting sources. The system can be developed together with the LEO communication system, and do not need to build a new system. The Hongyan LEO communication system under construction by China Aerospace and Technology Corporation (CASC) is adopted for the analysis in the paper. When served as space-based monitoring stations, the LEO satellites can jointly determine the precise orbits and clock errors of GNSS satellites and LEO satellites with the data from the mounted high precision GNSS monitoring receiver and the ground based monitoring stations. When served as navigation information broadcasting sources, the Assistant GNSS (AGNSS) architecture is used to broadcast assistant navigation information, and the general-purpose GNSS receiver can realize fast signal acquisition in the extremely complicate environment and achieve better antijamming capability for the navigation availability augmentation. For the navigation precision augmentation, besides the precise orbit, precise clock error, and integrity augmentation information, an additional navigation augmentation signal is broadcasted to realize global precise point positioning (GPPP) with sub-meter positioning precision level in dynamic mode and sub-decimeter precision level in static mode. The convergence time of precise point positioning is shorten from 30 minutes using a GNSS system alone to less than 5 minutes using a GNSS system together with the LEO global navigation augmentation system.","PeriodicalId":434266,"journal":{"name":"2018 European Navigation Conference (ENC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127614216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The modernization of current GNSS constellations, like GPS, and the deployment of new ones, like Galileo or BDS, broadcasting dual-frequency signals in the Aeronautical Radio Navigation Service (ARNS) bands will lead in the near future to a Dual-Frequency Multi-Constellation (DFMC) GNSS environment for civil aviation. This new GNSS environment with additional and enhanced signals will support navigation services with improved positioning performances and robustness.GNSS augmentation systems like ABAS, SBAS and GBAS also need to evolve to support the new DFMC environment. Standardization of these new DFMC GNSS elements is a key step before their approval for operational use in civil aviation. The SBAS DFMC Service Volume Prototype (DSVP) is a software tool developed specifically to support the upcoming standardization activities of SBAS DFMC use for civil aviation. This paper presents the up-to-date SBAS DSVP tool along with its evolutions to comply with the latest SBAS DFMC standard. The paper also provides some examples of achievable SBAS DFMC system and user performances to test various system configurations and/or different interpretations or utilizations of the SBAS DFMC standard.","PeriodicalId":434266,"journal":{"name":"2018 European Navigation Conference (ENC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114451817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A possible approach to mitigate the impact of jamming is the implementation of Pulse Blanking (PB) that is an effective mitigation technique for pulsed interference. Clean samples are however required for receiver processing. In order to achieve this condition, filtering can be used: the jamming signal usually sweeps large frequency bands. When filtering is applied, the jamming signal periodically enters and exits the filter bandwidth resulting in pulsed interference. For wide-band GNSS signals, a Filter Bank (FB) can be adopted: the input signal is split into several sub-bands and PB is applied independently on each sub-band. The jamming signal impacts only one sub-band at the time resulting in a sequence of pulses in the different sub-band channels. In this paper, sub-band signal processing is combined with robust Zero-Memory Non-Linearities (ZMNLs) and a general scheme for interference mitigation is proposed. In particular, PB is replaced by ZMNLs that introduce robustness to the processing of GNSS signals. Sub-band decomposition is performed using a uniform Discrete Fourier Transform (DFT) FB, which is efficiently implemented using polyphase decomposition. Different FB configurations and different ZMNLs are considered. Hardware simulations and real GNSS data are used to demonstrate the effectiveness of the mitigation schemes proposed.","PeriodicalId":434266,"journal":{"name":"2018 European Navigation Conference (ENC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128977653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
