Visualization

PPPx writes a .pos solution and an RTKLIB-compatible .stat file, so you can visualize results in the browser, with the bundled Python script, or with RTKLIB.

With the PPPx Web Viewer

The PPPx Web Viewer is a browser-based app for viewing PPPx results interactively. It takes a PPPx .pos or .stat file as input and offers two main views: a position time series and a map view of the solution. Being entirely browser-based, it needs no installation and works on any platform.

Just open app.pppx.dev and load a .pos or .stat file. The viewer can also process a RINEX observation file on the server with a fixed PPP configuration — see Try it online.

A PPPx solution in the PPPx Web Viewer

With Python: `plot_ppppos.py`

The plot_ppppos.py script in the repository’s scripts/ folder plots a .pos file. It can show either the position time series (east/north/up relative to the mean) or the full set including the receiver clock and ZTD.

# (1) position estimates only
../../scripts/plot_ppppos.py path/to/solution.pos -s

# (2) position, receiver clock, and ZTD
../../scripts/plot_ppppos.py path/to/solution.pos -a

Options:

Option	Effect
`-a`	Plot position and receiver clock and ZTD.
`-s`	Fixed (scaled) y-axis; otherwise the scale is automatic.
`-i`	Interactive plot window (otherwise a PNG is saved).

`-s` (position only)	`-a` (position + clock + ZTD)

With RTKLIB

For richer, interactive plots — including post-fit residuals — open the .stat file in RTKLIB’s RTKPLOT.

Open rtkplot (rtkplot.exe on Windows).
File → Open Solution-1 and select the PPPx .stat file.
Switch between the ground-track, position, and residual views.

You can open a second solution in the same window to compare two runs side by side.

Ground track	Position time series

Residuals vs. time	Residuals vs. elevation
