2022-07-06 12:53:00 【Proletarians】
The most direct file to understand the updated content of an open source library is readme.txt, Update the content by :
- NavIC (IRNSS) completely supported.
- RINEX 3.04 supported. BDS-3 and QZSS new signals added.
- RTCM 3.3 amendment-1 supported. MT1041/1131-7 (NavIC ephemeris/MSM)
added. - RTCM3 MT1230 (GLONASS code-phase biases) supported.
- RTCM3 MT4076 (IGS SSR) supported.
- GNSS singal ID changed: L1,L2,L5/3,L6,L7,L8,L9 -> L1,L2,L3,L4,L5.
- Only Windows 64bit APs supported. 32bit APs deleted.
- Windows scaled DPI APs supported for different DPI screens.
- Directories RTKLIB/app and RTKLIB/data reorganized.
- License clarified. See RTKLIB/LICENSE.txt.
- Bugs and problems fixed including GitHub Issues:
#461,#477,#480,#514,#540,#547,#555,#560.
From above 11 Click Update to see , It's mainly about rinex3.04 and rtcm3 Support for .
I'm not sure 11 Point of interest ,bugs Namely :
#461: ZED f9p strsvr ubx-> rtcm3 conversion
#477: ntrip browser map view not working
#480: Post releases on Releases tab instead of in RTKLIB_bin repo
#514: stec.c missing
#540: License in separate file
#547: Missing header <sys/select.h> in rtklib.h
#555: exec convbin find a problem
#560: Issue with Delta Clock C2 value
Specifically issue You can check the corresponding serial number to find a detailed problem description . From above 8 individual bugs Look at , It seems that there are no major updates worth paying attention to .
Look down again readme.txt, Will find api There are changes ( New addition / Optimize / Delete ), Namely :
The following APIs added:
code2freq(),sat2freq(),code2idx(),timereset(),setseleph(),getseleph(), decode_gal_fnav(),decode_irn_nav()
The following APIs modified:
obs2code(),code2obs(),setcodepri(),getcodepri(),tickget(),traceb(), getbitu(),getbits(),setbitu(),getbits(),rtk_crc32(),rtk_crc24q(), rtk_crc16(),docode_word(),decode_frame(),test_glostr(),decode_glostr(), decode_bds_d1(),decode_bds_d2(),decode_gal_inav(),input_raw(),input_oem4(), input_oem3(),input_ubx(),input_ss2(),input_cres(),input_stq(),gen_ubx(), gen_stq(),gen_nvs(),input_rtcm2(),input_rtcm3(),gen_rtcm3(),inputsol(), outprcopts(),outsolheads(),outsols(),outsolexs(),outnmea_rmc(), out_nmea_gga(),outnmea_gsa(),outnmea_gsv(),sbsdecodemsg(),strread(), strwrite(),strsvrstart(),strsvrstat(),showmsg()
The following APIs deleted:
lam_carr[],satwavelen(),csmooth(),satseleph(),input_gw10(),input_cmr(), input_tersus(),input_lexr(),input_gw10f(),input_cmrf(),input_tersusf(), input_lexrf(),gen_lexr(),strgetsel(),strsetsel(),strsetsrctbl(), pppcorr_read(),pppcorr_free(),pppcorr_trop().pppcorr_stec(), stsvrsetsrctbl(),init_imu(),input_imu(),lexupdatecorr(),lexreadmsg(), lexoutmsg(),lexconvbin(),lexeph2pos(),lexioncorr()
The following types modified:
obsd_t,eph_t,nav_t,rtcm_t,rnxctr_t,prcopt_t,rnxopt_t,ssat_t,raw_t,strsvr_t
The following types deleted:
lexmsg_t,lex_t,lexeph_t,lexion_t,stec_t,trop_t,pppcorr_t,exterr_t, half_cyc_t,imud_t,imu_t
The next step is to support the receiver , This part of the code is mainly in src/rcv in .
The next part is about all kinds of APs Update , Let's learn the two most important open source libraries AP Namely rtkpost and rtknavi 了 , Focus on the updates of these two programs , As follows :
RTKPOST:
TGD and BGD handling improved for Galileo and BDS. Always L1-L2 (E1-E5b for Galileo, B1-B2 for BDS) used for Iono-Free LC. Always I/NAV used for Galileo orbits and clocks. SP3-d format for precise ephemerides supported. CPU usage much improved in SD to DD conversion for ambiguity resolution. OpenBLAS linked instead of Intel MKL for fast-matrix computation. Option QZSS LEX and Input STEC for ionos-correction no longer supported. Option Input ZTD for troposphere correction no longer supported. AP RTKPOST_WIN64 and RTKPOST_MKL deleted.
RTKNAVI:
NMEA talker ID GQ and GI (NMEA 0183 4.11) for QZSS and NavIC supported. NMEA GQ/GB/GI-GSA/GSV sentences supported. Option Panel Font added. Menus reorganized in RTK Monitor. Menu Station Info added to RTK Monitor. Satellite positions in Skyplot by TLE data no longer supported. Menu LEX and Iono Correction deleted from RTK Monitor. AP RTKNAVI_WIN64 deleted.
stay rtkpost in , The highlight is the conversion from single difference to double difference in ambiguity calculation CPU Improve the efficiency of use , Use in fast matrix calculation OpenBLAS Replace MKL, among :OpenBLAS is an optimized Basic Linear Algebra Subprograms (BLAS) library based on GotoBLAS2 1.13 BSD version.( Optimal Linear Algebra Subroutine ),Intel MKL:Intel Math Kernel Library, Intel math core library . This explains the article 《rtklib The new version 2.4.3 b34 Test comparison 》 and 《RTKlib 2.4.3 b34 Data testing and performance analysis 》 Reasons for the improvement of operation efficiency .
summary : from readme.txt On the whole, I know what has been updated , Also know the key point of looking at the code , Next I'll start with src Start with the source code to see what happened before and after the update diff New add Of api. It is expected that this week will be on src Middle Division rcv Make a detailed summary of the update of , I hope you can communicate with each other .
