What is a 22O file

22O files mostly belong to RTKCONV. A .22O file stores GNSS observation data, conforming to the RINEX 3.04 format. It contains raw measurements collected by GNSS receivers, including pseudorange, carrier phase, Doppler shift, and signal-to-noise ratio from various satellite constellations (GPS, GLONASS, Galileo, BeiDou, etc.). These files are crucial for precise positioning, navigation, and timing applications, enabling techniques like Real-Time Kinematic (RTK) and Precise Point Positioning (PPP). The RINEX 3.04 format ensures standardized data exchange and interoperability between different GNSS software and receivers.

How to open 22O files

.22O File Won't Open? Here is What You Can Do

Because .22O files originate from specialized systems, they aren't universally openable.

  1. Identify the Source: These files typically come from surveyors or geospatial analysts using GNSS receivers, suggesting processing software like RTKCONV.
  2. Check the Header: Open the file in a text editor to inspect the first lines.
    • "RINEX VERSION" or "OBSERVATION DATA" confirms standard GNSS data.
    • "PK" or scrambled characters suggest a compressed or proprietary binary format.
  3. Use the Original Software: The original geospatial program is usually required. Try RTKLIB (RTKCONV), Trimble Business Center, or ask the sender.
  4. Use this Webpage: Drag and drop your .22O file here to detect its format, extract readable metadata, and preview the contents.

How to solve problems with 22O files

  • Associate the 22O file extension with the correct application.
  • Update your software that should actually open gnss observation data files. Because only the current version supports the latest 22O file format. Search, therefore, e.g. on the manufacturer website after an available RTKCONV update.
  • To make sure that your 22O file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
