Clock RINEX
Clock RINEX are one special RINEX file format. Like SP3, they are high end product that are post processed, not compatible with real time positioning.
Attaching a Clock RINEX file makes the provided context PPP compliant. It also unlocks new features in the command line, like:
- new temporal visualizations become available
- the Radio/Clk residual analysis becomes available
When targetting ultimate PPP results, it is required that the Clock RINEX files be expressed in the same timescale as the Observation RINEX.
If you fail in doing so, the -p logs will let you know by printing some warnings.
The toolbox allows projectting the SV clock states and resolved system time
with --clk if Graphical Mode is first enabled with -g.
If Clock RINEX files were loaded, it is possible to resolve such information as similarly done from radio messages. A residual analysis is also feasible between the clock state broadcasted over radio and the clock state refined by Clock RINEX.
Example:
./target/release/rinex-cli \
-f test_resources/NAV/V3/ESBC00DNK_R_20201770000_01D_MN.rnx.gz \
-f test_resources/CLK/V3/GRG0MGXFIN_20201770000_01D_15M_30S.CLK.gz \
-P GPS \
-g --clk --clk-residual
