State of the art context analysis with RINEXCLI

In this tutorial, we'll use a set of two files that are hosted in this repo to demonstrated what rinex-cli (our main application) is capable of.

Load the context and run a quick identification

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

The file contains vehicles that belong to GPS, Glonass, BeiDou, QZSS, Galileo, EGNOS, BDSBAS and SDCM.

Sampling conditions are good and very steady.

Now proceed to record analysis by removing the -i special flag.
To reduce the quantity of data, we'll focus on GPS and observations on L1

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

We host overlapping BRDC navigation data for this day and context.
The file was generated by the same receiver and is also very high quality.

Run a quick identification of this one specifically:

rinex-cli -i \
   -f test_resources/CRNX/V3/ESBC00DNK_R_20201770000_01D_MN.rnx.gz

The file contains Ephemeris for the same constellations as the observatoin file.
This means

The time frame for BRDC NAV is 2020-06-24T19:50:00 GST - 2020-06-26T00:00:00 GPST.
