This allows processors to seamlessly consume such data without the need to input these parameters manually. The technical development phase of the initial version of the standard has now been deemed complete and is currently undergoing the last remaining procedural steps towards adoption as a formal standard by the Institute of Navigation. This paper reports on the activities of the working group since September 2018 and summarizes the final products of the standard. It also reports on examples of early adoption by academic, research, and open source SDR projects. This includes an example where, as intended, capabilities covered in the standard have been expanded to describe custom data embedded within sampled data streams. Also included is an example where the standard is used to describe non-GNSS data. Several examples of commercial adoption are also documented in this paper. The standard website (sdr.ion.org) includes a repository containing SDR files of various topologies and formats. The working group is currently in the process of providing the satnav observables for these datasets using well-known SDRs in order to serve as a reference for those working to adopt the standard products into their own software projects. This paper also includes results from this effort. 32nd International Technical Meeting of the Satellite Division of the Institute of Navigation (ION GNSS+ 2019), Miami, Florida, September 16-20, 2019 3785 https://doi.org/10.33012/2019.17027 INTRODUCTION The ION GNSS SDR Metadata Standard arose out of a need that was first discussed at the ION GNSS+ 2013 meeting in Nashville Tennessee, to come up with a standard way to describe the sampled data file formatting and other important parameters relevant to satnav SDR processing (referred to as GNSS SDR metadata), in such a way that an SDR could conceptually handle any of these files without having to manually enter these parameters. After 6 years of voluntary effort by the Standard Working Group, this vision has largely been realized and this free and open standard development has been deemed complete. All technical documentation and reports generated as part of this development can be found in http://sdr.ion.org/presentations-and-publications.html. The draft standard document can be found in https://github.com/IonMetadataWorkingGroup/GNSS-Metadata-Standard/tree/master/Specifications/documentation. This paper represents the final report on this effort. Activities since September 2018 and the final steps toward formal ratification are summarized below. An overview of the normative reference software and current status is described next. The remainder of the paper reports on current adoption and use cases of the standard by academia and research organizations, as well as availability of commercial products that have adopted the standard.

Firstly, the odometer-based method, which are proposed in our previous research [1], is concretized to be implemented for general cases. This method detects faults in the GNSS solution due to satellite failure or local effects using both odometry and track geometry of the onboard system. It enables to monitor all three-dimensional solution error so that higher sensitivity for the fault detection can be achieved. Secondly, single-axis accelerometer-based approach is newly proposed. Positioning architecture of this method is designed in traveling distance domain with the configuration of single-axis accelerometer installed along the forward direction. The diagnosis of GNSS signal can be done easily in one-dimensional space. Therefore, the latter method is expected to give greater sensitivity to detect GNSS failures while maintaining a relatively simple architecture. Both methods are tested in simulation, and their abilities for detecting fault in GNSS signal are investigated","PeriodicalId":381025,"journal":{"name":"Proceedings of the 32nd International Technical Meeting of the Satellite Division of The Institute of Navigation (ION GNSS+ 2019)","volume":"195 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115646932","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}
