Users can now upload GNSS vectors into OPUS projects, including vectors derived from either a single-base real-time kinematic (RTK) setup or from a real-time network (RTN), for evaluation, quality assessment, and inclusion in a GNSS survey network for least squares adjustment.
Use the new GNSS Vector Exchange (GVX) file format to transfer data from various manufacturer hardware to OPUS Projects 5.0.

Getting started:

• Use sample data that are available online and in the GVX file format.
• Talk to your vendor about converting your own GNSS vector data to the GVX file format.

For an overview of the new features check out the recent NGS webinar from May 20, 2021.

OPUS-Projects for RTK/RTN Vectors

NGS is developing OPUS-Projects so that GNSS vectors, including those from real-time kinematic (RTK) surveys, can be uploaded to a survey network for least-squares adjustment and submittal to NGS for publication. This has required developing a standardized GNSS vector exchange format known as GVX.
