-**NB: RINEX conversion is currently an experimental facility based on the [pygnssutils pyrinexconv CLI utility](https://github.com/semuconsulting/pygnssutils#rinexconvert). See [pygnssutils release notes](https://github.com/semuconsulting/pygnssutils/releases/tag/v1.2.1) for details of current functionality and limitations**. The intention is to enhance functionality in future releases.
