Convert RNX to another file type

To convert your RNX file to another format, you need RTKLIB or other GIS software.

Convert a file to RNX

To convert other file formats to the "GPS Data Exchange" file type, you need software like RTKLIB or a similar tool.

About RNX files

A .RNX file is primarily a RINEX (Receiver Independent Exchange Format) file, the global standard for storing raw GNSS/GPS satellite observation data. Unlike standard GPX or KML files which store simple latitude/longitude tracks, an RNX file contains complex raw measurements (carrier phase, pseudorange, Doppler) recorded by survey-grade receivers.

The Problem: Because .RNX files store raw sensor data rather than calculated positions, they cannot be opened directly in Google Maps, Google Earth, or standard GPS viewers. They are text-based (ASCII) and can be opened in a text editor like Notepad++, but the data is unreadable to humans without technical knowledge. To use this data, you typically need to "post-process" it using scientific software to calculate accurate coordinates, or convert it into a visual format.

The Solution:

For Visualization: Process the file to generate a track, then convert the output to KML or GPX for use in Google Earth.
For Analysis: Convert the raw data to CSV to analyze signal strength and satellite visibility in Microsoft Excel.
For Archiving: The .RNX format itself is the gold standard for long-term archiving of raw survey data.

Note: In very rare legacy cases, an .RNX file may be a settings file for RealPlayer, used to configure streaming media playback.

Convert.Guru analyzes your RNX file, detects the exact format, and lets you read the text inside.

Users also converted 25O, GZ, T04, CRX, ZIP, C4D, XPT, LCP, PLO and OBS files.

FAQ

If you want to convert RNX file to OBS, INI, CFG, CONF, CONFIG, JSON, XML, YAML, YML, TOML, ENV or PROPERTIES, you can use RTKLIB or similar software from the "GNSS Observation Data Storage" category. In the File menu, look for Save As… or Export….

To convert ZSHRC, CONF, RCFILE, GITCONFIG, RC, PLIST, BASHRC, CONFIG, PROFILE, INI, PREFS or CFG files to RNX, try RTKLIB or another comparable tool in the "GNSS Observation Data Storage" category.

The RNX Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our RNX converter.
