Clock States plot

--clk allows visualizing SV clock states, usually described over radio broadcast from a Navigation RINEX file, but it can also plot this information contained in a Clock RINEX file or SP3 file. In this case, this operation is convenient and helps seeing the micro differences between the broadcast message, and the post processed / refined product.

Request Clock state visualization by enabling -g and --clk:

rinex-cli \
    -f test_resources/NAV/V3/ESBC00DNK_R_20201770000_01D_MN.rnx.gz \
    -P GPS \ # reduce data quantity
    -g --clk

Loading a Clock RINEX at the same time so we get the comparison

rinex-cli \
    -f test_resources/NAV/V3/ESBC00DNK_R_20201770000_01D_MN.rnx.gz \
    -P GPS \ # reduce data quantity
    -g --clk

Once both products have been loaded, the residual error between the broadcast message and the high precision product is requested with --clk-residual

rinex-cli \
    -f test_resources/NAV/V3/ESBC00DNK_R_20201770000_01D_MN.rnx.gz \
    -P GPS \ # reduce data quantity
    -g --clk-residual
