Thus, IGS files must exist for 1 day before and after the specified begin and end dates, unless the -igs_span flag is set. 首先下载2006-12-13的星历和钟差数据 gipsy@ubuntu:~/GPS_DataProc/test/igs$ igs2flinn.pl -b 2006-12-14 -e 2006-12-14 2006-12-13: igsclk file does not exist at /opt/goa-6.1.2/bin/igs2flinn.pl line 121 下载2006-12-13的星历和钟差数据 gipsy@ubuntu:~/GPS_DataProc/test/igs$ igs2flinn.pl -b 2006-12-14 -e 2006-12-14 2006-12-15: igsclk file does not exist at /opt/goa-6.1.2/bin/igs2flinn.pl line 121 下载2006-12-15的星历和钟差数据 所需文件为： -r--r--r-- 1 gipsy gipsy 1004881 Dec 29 2006 igs14053.clk.Z -r--r--r-- 1 gipsy gipsy 94785 Dec 29 2006 igs14053.sp3.Z -r--r--r-- 1 gipsy gipsy 1033153 Dec 29 2006 igs14054.clk.Z -r--r--r-- 1 gipsy gipsy 94801 Dec 29 2006 igs14054.sp3.Z -r--r--r-- 1 gipsy gipsy 978763 Dec 29 2006 igs14055.clk.Z -r--r--r-- 1 gipsy gipsy 95049 Dec 29 2006 igs14055.sp3.Z gipsy@ubuntu:~/GPS_DataProc/test/igs$ igs2flinn.pl -b 2006-12-14 -e 2006-12-14 gipsy@ubuntu:~/GPS_DataProc/test/igs$ 得到的结果是： -rw-r--r-- 1 gipsy gipsy 116 Feb 26 12:38 2006-12-14.ant.gz -rw-r--r-- 1 gipsy gipsy 1346 Feb 26 12:38 2006-12-14.eo.gz -rw-r--r-- 1 gipsy gipsy 43 Feb 26 12:38 2006-12-14.frame.gz -rw-r--r-- 1 gipsy gipsy 98811 Feb 26 12:38 2006-12-14.pos.gz -rw-r--r-- 1 gipsy gipsy 80 Feb 26 12:38 2006-12-14.shad.gz -rw-r--r-- 1 gipsy gipsy 151475 Feb 26 12:38 2006-12-14.tdp.gz Examples: igs2flinn.pl -b 2006-01-02 -e 2006-01-09 Will make FLINNR formatted files, *.pos.gz, *.tdp.gz, *eo.gz, *.shad.gz, *frame.gz, *ant.gz for the time span 2006-01-02 to 2006-01-09 from IGS files in the same directory. This directory could now be used with the `-orb_clk' flag of gd2p.pl. igs2flinn.pl -b 2006-01-02 -e 2006-01-09 -flinn_dir FLINNR Will make FLINNR formatted files, *.pos.gz, *.tdp.gz, *eo.gz, *.shad.gz, *frame.gz, *ant.gz for the time span 2006-01-02 to 2006-01-09 from IGS files in the FLINNR subdirectory. Note the necessary IGS files could have been fetched to the current directory with the command: igs_orbits_clks_fetch.pl -b 2006-01-01 -e 2006-01-10 如果不下载处理当天的前一天和后一天的IGS轨道和星历数据，可采用下面的选项： Instead of generating files that span 30 hrs, as the standard FLINNR product does, generate files spanning 00:00:00 - 23:45:00 for each of the daily IGS files. This is the span of the rapid and final IGS products. For the longer 30 hr time spans, the IGS files are cat'd together appropriately. 4.goa_prod_ftp.pl 从JPL的服务器下载所需的轨道和星历（由于NASA对中国用户的限制，目前无法使用） /opt/goa-6.1.2/bin/goa_prod_ftp.pl -d yyyy-mm-dd DEFAULT flinnR gets orbit clock and associated files suitable for use with gd2p.pl -hr option will fetch high rate clocks for *R* products Examples: /opt/goa-6.1.2/bin/goa_prod_ftp.pl -d 2009-12-03 will fetch flinnR products /opt/goa-6.1.2/bin/goa_prod_ftp.pl -d 2010-10-01 -s ultra will fetch ultra products Ultra is updated every hour with about 1-hour latency 5.sta2antxyz.pl 根据测站的ID制作成ant的相位差异xyz文件 Help on module sta2antxyz: NAME sta2antxyz FILE /opt/goa-6.1.2/bin/sta2antxyz.py PURPOSE: Define phase variation file (xyz file) given a station ID, and using as input a sinex file with antenna information for the specified station, and an antex file with phase variations for the antenna type. DESCRIPTION: Given a station ID, IGS sinex file, and IGS antex file, this program will create a phase variation file (xyz file) for that station. The xyz file is the file used by GIPSY's gd2p.pl program. The antex file provides the phase center with respect to the reference point (typically the ARP), and a map with respect to the specified phase center. As such, for the output xyz file always contains phase variations with respect to the reference point (typically the ARP), computed as the sum total of the specified phase center and map with respect to the phase center. USAGE: sta2antxyz.py -s sss1 sss2 ... -sinex sinexfile1 sinexfile2 ... -antex antexfile -o xyzfile OPTIONS: -s sss1 sss2 ... List of four character station IDs for which antenna phase variation maps are desired. (Case insensitive) -sinex sinexfile1 sinexfile2 ... List of sinex files from which antenna and radome type for station is defined. Sinex files should contain the data block: SITE/ANTENNA This data block is checked for the antenna and radome type at the station, and this information is used to query the antex file to generate the xyz file for that station. igs.snx文件下载地址 : Possible IGS Sinex files include: ftp://igscb.jpl.nasa.gov/igscb/station/general/igs_with_former.snx ftp://igscb.jpl.nasa.gov/igscb/station/general/igs.snx The file igs_with_former.snx includes historical IGS sites. -antex antexfile Antexfile contained phase variation information for antenna/radome combinations. igs.antex文件下载地址: IGS Antex files can be found at: igscb.jpl.nasa.gov/igscb/station/general/ -o xyzfile Name of output xyzfile that will contain antenna phase variation maps for all stations in input list. Note that antenna phase variation maps will be appended to this file if already exists. -d yyyy-mm-dd Date at which phase variation map required (at 12:00:00). Default date is today (at 12:00:00). -h, -H, -help Prints this man page. EXAMPLE: sta2antxyz.py -s jplm algo -sinex igs_with_former.snx -antex igs05_1421.atx -o jplalgo.xyz -d 2006-01-01 sta2antxyz.py -s jplm algo -sinex igs.snx -antex igs05.atx -o jplalgo.xyz -d 2005-01-01 In the above example, antenna calibration maps for stations JPLM and ALGO are appended to the file jplalgo.xyz, by determining antenna information at the 2 sites on 2006-01-01 from the igs_with_former.snx sinex file, and using that antenna information to derive antenna calibrations from the igs05_1421.atx antex file.
