Graph mode

Graph Mode (-g)

Graph mode, for the lack of a better term, is there to generate graphical views of the output products.

The typical use is RINEX record analysis. RINEX-Cli allows analyzing all supported types of RINEX files.

Graph mode is requested with -g. This mode has a lot of options, when unsure, do not hesitate to use the command line helper:

rinex-cli \
    -f test_resources/CRNX/V3/ESBC00DNK_R_20201770000_01D_30S_MO.crx.gz -g -h

Options are sorted according to the type of files that have been loaded into the context.

OBS RINEX visualizations

When GNSS observations have been lodaed, you can request their visualization with -o,--obs.

These files have tendency to be quite heavy, for demonstration purposes we will focus only a few SV:

rinex-cli \
    -P G05,G15,G08 \ # reduce data quantity
    -f test_resources/CRNX/V3/ESBC00DNK_R_20201770000_01D_30S_MO.crx.gz -g -o

When observable visualization is requested, all contained observations will be depicted.
In this example, Doppler shifts and received SSI are some of the available measurements:

If you applied a filter condition like -P L1C to retain only a specific observable, only this one is to be depicted. In our previous examples, we obtained all observables but only from 3 vehicles.

Note that observable visualization also applies to Meteo sensors:

Differential Code Bias (DCB)

Once OBS RINEX is loaded, we can also request DCB visualization, with --dcb:

rinex-cli \
    -P G05,G15,G08 \ # reduce data quantity
    -f test_resources/CRNX/V3/ESBC00DNK_R_20201770000_01D_30S_MO.crx.gz -g --dcb

DCB is rendered in a dedicated plot:

Code Multi Path Bias (MP)

Once OBS RINEX is loaded, we can also request code Multipath (MP) bias visualization, with --mp:

rinex-cli \
    -P G05,G15,G08 \ # reduce data quantity
    -f test_resources/CRNX/V3/ESBC00DNK_R_20201770000_01D_30S_MO.crx.gz -g --mp

Code MP bias is rendered in a dedicated plot:
