ION requests comment on GNSS SDR Metadata Standard

September 15, 2017  - By

The Institute of Navigation’s GNSS Software Defined Radio Metadata Standard working group is seeking public comment on the standard through Dec. 31.

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.

This specification standardizes the metadata associated with GNSS SDR sampled data files and the layout of the binary sample files.

The GNSS SDR Metadata Standard defines parameters and schema to express the contents of SDR sample data files. The standard 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.
