Graph Observation

Carrier Signal plots

Loading GNSS signal observations into the toolbox, allows their dedicated plot which you can request with -o,--obs.

Like Clock RINEX and other products that have a high sample rate, these files are quite heavy, therefore it is recommended to at least focus on the Constellation or the couple of Satellites you're interested in.

rinex-cli \
    -P G05,G15,G08 \ # reduce data quantity, refer to Preprocessing toolbox
    -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 signal, only this one is to be depicted.
In our previous examples, we obtained all observables but only from 3 vehicles.

Note that -o,--obs (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:

GNSS signal combinations

RINEX-Cli knows how to form all standard GNSS carrier signal recombinations.
They are formed in a dedicated plot, in this example, we request both the Geometry Free combination to be plotted:

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