V0.16

[gwbres]

RINEX V0.16 comes with many improvements.

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/V3/GRG0MGXFIN_20201770000_01D_15M_ORB.SP3.gz
-P G15,G16,G31 \
-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/V3/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

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/NAV/V3/ESBC00DNK_R_20201770000_01D_MN.gz
-f test_resources/CLK/V3/GRG0MGXFIN_20201770000_01D_30S_CLK.CLK.gz
-f test_resources/SP3/V3/GRG0MGXFIN_20201770000_01D_15M_ORB.SP3.gz
-P GAL
-p -c rinex-cli/config/rtk/gpst_ppp_basic.json | tee logs.txt

Code based PPP + CGGTTS

./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/V3/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.
In V0.16 state we can parse the file correctly but no analysis modes are available.
This will be introduced in following versions.

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)

What's next

• Hifitime upgrade to V4.0
• BeiDou in SPP/Code based PPP opmode
• QZSS in SPP/Code based PPP opmode
• More options to process DORIS
• Upgrade in the QC capabilities
• Glonass in SPP/PPP will come after BDS and QZSS
