v0.16.1

RINEX V0.16 comes with many improvements.

V0.16.1 is the first official release of the V0.16 serie. V0.16 simply had an error in its auto documentation process

Clock RINEX

This file format is now correctly supported and we can take advantage of it for precise positioning.
It is also added to analysis opmodes, try this for Clock RINEX | SP3 Clock and BRDC Clock comparison for example

./target/release/rinex-cli \
   -f test_resources/NAV/V3/ESBC00DNK_R_20201770000_01D_MN.gz \
   -f test_resources/CLK/V3/GRG0MGXFIN_20201770000_01D_30S_CLK.CLK.gz \
   -f test_resources/SP3/GRG0MGXFIN_20201770000_01D_15M_ORB.SP3.gz \
   -P GPS -g --clk

PPP processing time

RTK-RS core upgraded to V0.5: 50x computation speed improvement.
The following now runs in about 3sec on my computer, against 2'30 previously

./target/release/rinex-cli \
   -f test_resources/CRNX/V3/ESBC00DNK_R_20201770000_01D_30S_MO.crx.gz \
   -f test_resources/NAV/V3/ESBC00DNK_R_20201770000_01D_MN.gz \
   -f test_resources/CLK/V3/GRG0MGXFIN_20201770000_01D_30S_CLK.CLK.gz \
   -f test_resources/SP3/GRG0MGXFIN_20201770000_01D_15M_ORB.SP3.gz \
   -P GPS \
   -p -c rinex-cli/config/rtk/gpst_spp_basic.json | tee logs.txt

SSI/SNR against SV elevation

SSI against SV Elevation visualization to emphasize their correlation

./target/release/rinex-cli \
   -f test_resources/NAV/V3/ESBC00DNK_R_20201770000_01D_MN.gz \
   -f test_resources/CLK/V3/GRG0MGXFIN_20201770000_01D_30S_CLK.CLK.gz \
   -f test_resources/SP3/GRG0MGXFIN_20201770000_01D_15M_ORB.SP3.gz \
   -P GPS -g -o

Code PPP

New positioning method: Code Based PPP which gives the best results ever obtained.
Run this to try the new strategy:

./target/release/rinex-cli \
   -f test_resources/CRNX/V3/ESBC00DNK_R_20201770000_01D_30S_MO.crx.gz \
   -f test_resources/CRNX/V3/ESBC00DNK_R_20201770000_01D_30S_MO.crx.gz \
   -f test_resources/SP3//GRG0MGXFIN_20201770000_01D_15M_ORB.SP3.gz \
   -P GPS -p -c rinex-cli/config/rtk/gpst_ppp_basic.json

Code based PPP + CGGTTS

Code based PPP strategy applies similarly to CGGTTS special solutions

./target/release/rinex-cli \
   -f test_resources/CRNX/V3/ESBC00DNK_R_20201770000_01D_30S_MO.crx.gz \
   -f test_resources/NAV/V3/ESBC00DNK_R_20201770000_01D_MN.gz \
   -f test_resources/CLK/V3/GRG0MGXFIN_20201770000_01D_30S_CLK.CLK.gz \
   -f test_resources/SP3/GRG0MGXFIN_20201770000_01D_15M_ORB.SP3.gz \
   -P GAL,GPS \
   -p --cggtts \
   -c rinex-cli/config/rtk/gpst_ppp_basic.json | tee logs.txt

DORIS

DORIS RINEX (special file format) is partially introduced.
V0.16 can parse the file correctly but no analysis is available yet.

Other

• Improved plotting performances in a couple of spots (time to generate plots)
• Huge improvements of the File Production interface. Generate standardized RINEX easily,
  as you would expect in profesionnal contexts like laboratories and production agencies.
• First -p tests with Galileo and they give even better results
• First -p tests with Mixed constellations (GPS + GAL)
