The main error of satellite navigation is caused by tall buildings, which reflect or block the signals. To estimate the delay of these reflections, we developed a method based on signal power measurements from multiple carrier frequencies. This article presents this new method, together with an analysis of its sensitivity to signal power measurement noise. The findings show that the novel method’s performance is better than state of the art methods, as long as the standard deviation of the measurement noise is relatively low. Thus, the method can be used to correct time of flight measurements, especially for satellite navigation systems.","PeriodicalId":123786,"journal":{"name":"2020 International Conference on Localization and GNSS (ICL-GNSS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130227826","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}

Therefore, we propose multipath-assisted device-free localization with magnitude and phase information (MAMPI), a DFL system that employs ultra-wideband (UWB) channel impulse response (CIR) measurements between a transmitter and receiver and thereby benefits from multipath propagation. We implement a model that includes raytracing, diffraction, and inaccuracies of measurements in a validated error model. The multipath-assisted DFL system creates feature vectors at any position based on magnitude and phase measurements of each multipath component (MPC) of the CIR. We evaluate our new approach with a position error probability based on the propagation model including errors, as well as a distance metric of the feature vector of the positions. We compare the performance of the system with a line-of-sight solution with four instead of two nodes and variants of magnitude-only and phase-only approaches. By combining the magnitude and phase measurements of a multipath-assisted DFL system, we achieve a position error probability that is similar to the conventional DFL system.","PeriodicalId":123786,"journal":{"name":"2020 International Conference on Localization and GNSS (ICL-GNSS)","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115256727","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 probability of Line-of-Sight (LoS) propagation will be intuitively higher for aerial users than for terrestrial users and this will provide a trade-off between increased capacity and increased interference. Our paper analyzes theoretically this trade-off and proposes solutions based on downlink multiantenna beamſorming and joint optimization of the signal-to- interference ratio of multiple aerial users. It is shown that Multiple-Input-Single-Output solutions offer the most convenient tradeoff between complexity and capacity/interference performance.

The state-of-the-art techniques processing dual-frequency GPS and GLONASS data involve taking differences between the signals, which has become unfeasible now that there are half a dozen GNSS systems providing observations over various frequencies and modulations, resulting in over a hundred different observable signals with distinct properties. This work demonstrates joint estimation of all the station and satellite biases along with ionospheric delays, receiver clock offsets and carrier integer ambiguities from undifferenced raw multi-GNSS pseudorange and carrier phase observations. A sparse robust linear least squares solver combined with integer ambiguity resolution was implemented in MATLAB and its feasibility demonstrated using GPS, GLONASS, Beidou, and Galileo observations from MGEX network and post-processed satellite orbit products from ESOC. The results show that the method is computationally feasible and has high enough success rate to justify further study.","PeriodicalId":123786,"journal":{"name":"2020 International Conference on Localization and GNSS (ICL-GNSS)","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131691127","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}

With hundreds of networks being deployed in a short amount of time, NarrowBand IoT (NB-IoT) is stealing the LPWAN market shares from its competitors. The deep indoor coverage of NB-IoT guarantees the energy-efficient communication link between a device and a nearby base station. We believe we are the first to perform signal strength-based outdoor localization experiments with this up-and-coming technology. Instead of simulating the experiments, we face the challenges of working with real measurements in a real-world city-scale environment. In contrast to satellite-based solutions, the position of a mobile device equipped with a small battery can be estimated in indoor and outdoor environments for several years. In this research, we investigate the accuracy of NB-IoT localization, using the Received Signal Strength (RSS) to a single NB-IoT base station antenna. We evaluate three outdoor RSS-based algorithms: proximity, ranging and optimized fingerprinting. The experiments result in a mean location estimation error of 340 m, 320 m and 204 m, respectively.","PeriodicalId":123786,"journal":{"name":"2020 International Conference on Localization and GNSS (ICL-GNSS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128122467","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 system denies global navigation satellite system (GNSS) signals to any unwanted receivers while maintaining navigation capability for desired ones, with required modifications. The interference impact on GNSS signals is evaluated, as these are required to minimize the influence of the jamming system to other non-targeted GNSS services. A laboratory set-up demonstrates the validity of these bounds, showing what interference effects should be considered in receiver design. The area of influence and impact on GNSS receivers is analyzed and simulated. The jamming-pseudolite system is a plausible concept for alternative navigation.","PeriodicalId":123786,"journal":{"name":"2020 International Conference on Localization and GNSS (ICL-GNSS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130413429","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}

In order to operate spoofing in a real environment, we designed and implemented a portable, configurable, low-cost GPS spoofer exploiting a software-defined radio (SDR) implementation and a low-cost front-end. Such a tool has been exploited to set up a test campaign trying to mislead the Position, Velocity and Time computation of different Android™ smartphones. The effects of such simplistic spoofing attack on the smartphone GNSS has been assessed observing raw measurements and the evaluated positions and time. The main findings of this work showed that modern Android™ devices have a remarkable resilience to simplistic spoofing attacks, highlighting in parallel further potential weaknesses to be protected by means of practical defence mechanisms and countermeasures to spoofing.","PeriodicalId":123786,"journal":{"name":"2020 International Conference on Localization and GNSS (ICL-GNSS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124449512","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}
