Post Processing RINEX Files to Generate a Trajectory

[Nathan Hubbard]

I am using the Swift Multi Starter Kit and I'm having trouble creating a trajectory with quality of 1 (fixed points) using RTKPOST. The Swift console is showing that the Rover is receiving Fixed coordinates while it is observing. During observation it shows that it is observing 8-9 satellites. The RTK trajectory on the console looks great, but when I try to generate a trajectory using RTKLIB, all of the points are a quality of 5, which if I recall correctly, is only accurate within 10-15 meters. To be specific, I am converting the swift-gnss.sbp.json files to RINEX using the "sbp2rinex.exe" using the instructions found here:

I downloaded the sample RINEX files which are the RINEX 3.0 format from the link on the web page above and successfully processed them using RTKPOST and received over 90% fixed points in the trajectory. I then attempted to apply those same RTKPOST settings to process my files and I still only get points with a quality of 5.

Does anyone have a  process for creating trajectories from that can be used in other GIS tools like Google Earth, Global Mapper or ArcGIS? My goal is to be able to create a KML or SHP trajectory from the swift generated JSON or RINEX files. I then want to be able to pull it into GIS applications and compare Rover trajectory to surveyed base station coordinate and compare to Ortho Imagery.

Any help would be greatly appreciated. Thanks!
