    ION requests final comments on GNSS SDR Metadata Standard

    Logo: ION

    The Institute of Navigation’s GNSS Software Defined Radio Metadata Standard working group is seeking its second and final public comment on the standard through Nov. 30.

    In recent years, there has been a proliferation of software-defined radio (SDR) data-collection systems and
    processing platforms designed for GNSS receiver applications or those that support GNSS bands.

    For post-processing, correctly interpreting the GNSS SDR sampled datasets produced or consumed by these systems has historically been a cumbersome and error-prone process. This is because these systems necessarily produce datasets of various formats, the subtleties of which are often lost in translation when communicating between the producer and consumer of these datasets.

    The GNSS SDR Metadata Standard standardizes the metadata associated with GNSS SDR sampled data files and the layout of the binary sample files.

    The standard defines parameters and schema to express the contents of SDR sample data files. It is designed to promote the interoperability of GNSS SDR data-collection systems and processors. The metadata files are human readable and in XML format.

    A compliant open-source C++ API for reading metadata and binary samples is also officially supported to promote ease of integration into existing SDR systems.

    Comments can be made by going to sdr.ion.org and clicking on “Submit a Comment.” Public comments are being accepted through Nov. 30.

  • OGC requests comments on proposed Quality of Service and Experience DWG

    The Open Geospatial Consortium (OGC) requests comments on the charter for a proposed Quality of Service and Experience (QoSE) Domain Working Group (DWG).

    Spatial data now plays a critical role in the smooth functioning of contemporary society. From aiding emergency workers during crises to empowering businesses to make informed decisions, the reliable availability of the spatial data infrastructures (SDIs) that provide this critical spatial information is more important than ever.

    Yet, despite their critical nature, SDIs may suffer from sub-optimal configuration, malfunctioning hardware, or other factors that ultimately affect the accessibility of that data.

    The closely related fields of Quality of Service (QoS) and Quality of Experience (QoE) deal with estimating, reporting, and improving the experienced quality of communication between the components of distributed systems to inform the SDI users of the suitability of the service for the users’ needs.

    Organizations must establish a reliable SDI and measure, improve, and communicate information about QoS criteria — such as availability, performance, and capacity of SDI components — to end users. Mature tools for measuring and analyzing the QoS of these SDI components do exist, but there is little to no support for a standardized way of communicating the expected QoS level of the services to the end users and/or their analysis tools.

    The OGC QoSE DWG will provide a forum for discussing the evaluation of the QoS and QoE of an SDI as whole, and, when appropriate, propose corrections and enhancements to the existing OGC Standards (or externally governed standards) and guidance to make it easier to improve the experienced quality of Spatial Data Services.

    Further, the QoSE DWG will provide a forum for presenting, discussing, and sharing knowledge about evaluating and improving the QoS and QoE of Spatial Data Services from the perspective of the applications and organizations relying on these services for delivering timely and accurate spatial information to the end users.

    The draft charter for the QoSE DWG is available for download. Comments are requested by Nov, 15 and can be submitted to [email protected].

  • OGC requests participation in its marine working group

    The Open Geospatial Consortium (OGC) is calling for public participation in its newly established Marine Domain Working Group (Marine DWG).

    The Marine DWG was established to address applicability of the OGC standards baseline with regards to marine geospatial data, and to ensure knowledge is exchanged effectively between the relevant standards organizations, the OGC membership, and the broader geospatial community.

    Geospatial data in the marine domain has been successfully standardized for navigational purposes by hydrographic agencies for many years. This has allowed mariners to safely navigate oceans, ports and waterways anywhere on earth.

    However, the core data that support this activity is now in demand for a much wider range of applications, including environmental protection, emergency response, offshore energy, fisheries and more. As such, interoperability of this data is more important than ever before.

    While this group will not create new standards, it will be an open forum to discuss and understand any issues, concerns, or barriers to interoperability with the aim to ensure that marine data can be used effectively by the wider community.

    The OGC is looking for interested parties to assist the Marine DWG in achieving its goals. Details on the Marine Domain Working Group are available, along with the charter. Interested parties can join the email list.
