-Although data processing for obtaining high-accuracy PVT solutions is out of the scope of GNSS-SDR, we provide a module that can compute simple least square solutions (stored in GIS-friendly formats such as [GeoJSON](http://geojson.org/geojson-spec.html) and [KML](http://www.opengeospatial.org/standards/kml), or transmitted via serial port as [NMEA 0183](https://en.wikipedia.org/wiki/NMEA_0183) messages), and leaves room for more sophisticated positioning methods by storing observables a [...]

+* **RTCM SC-104** provides standards that define the data structure for differential GNSS correction information for a variety of differential correction applications. It was developed by the Radio Technical Commission for Maritime Services ([RTCM](http://www.rtcm.org/overview.php#Standards "Radio Technical Commission for Maritime Services")) and has become an industry standard for communication of correction information. GNSS-SDR implements RTCM version 3.2, defined in the document *RTC [...]

 **Important note:**
 
 In order to get well-formatted GeoJSON, KML and RINEX files, always terminate ```gnss-sdr``` execution by pressing key ```q``` and then key ```ENTER```. Those files will be automatically deleted if no position fix have been obtained during the execution of the software receiver.
