新一代RINEX标准格式及其应用-谷守周

RINEX＊谷守周1,2,秘金钟1,3,党亚民1,2(1.,100039;2.,266510;3.,430079)　　　:随着GALILEO计划的实施、美国GPS和俄罗斯GLONASS现代化以及SBAS系统的使用,综合利用各个系统的卫星信号可以提高定位精度及其可靠性。为了适应新增卫星导航系统的信号频率和观测值的不同,在RINEX第二版数据交换格式的基础上产生了RINEX第三版。本文讨论了RINEX第二版中的2.10和RINEX第三版中的3.00的格式之间的差异,并论述了RINEX3.00格式的相关应用情况。:RINEX3.00;GPS;GLONASS;GALIELO;SBAS:P228　　:A　　:1008-9268(2009)04-0052-07　GNSS()GNSS[1]。,,RINEX(ReceiverIndependentExchangeFormat)。。,。,RINEX,RINEX。GALILEO,GPSGLONASSSBAS,(),RINEX[2]。RINEX2.10RINEX3.00,3.00。1　RINEXRINEXWernerGurtner1989[3]。,EUREF89(GPS)GPS。460GPS[1]。RINEX:RINEX,。1.1　RINEXRINEX11989。1.2　RINEXRINEX21990。RINEX:(GPS)、(GPS)、()、GLONASS(GLO-NASS)、GEO(GPS(GEO))()。RINEXVersion2.10,Ver-sion2.11,Version2.20。1.3　RINEX·52·GNSSWorldofChina/2009.3＊:2009-05-04:863(2007AA12Z313,2006AA12Z306);(1469990624202)。GALILEOGPS,、,,。,RINEX3.00。:;GPS;;GLONASS;SBAS。SBAS:(EGNOS),(WAAS),(MSAS)。2　RINEX3.00RINEX3.00GPSGLONASSRINEX2.10,SBASRINEX2.11,RINEX2.10,RINEX3.00。,。2.1　,。2.10,L(GALIELO),B(SBAS)。2.2　。,,“ENDOFHEADER”。,61～80,1～60。2.1080,3.00。2.2.1　文件头部分1),3.00,2.10NNSSGALILEO,E。2)3.00(MARKERTYPE)。3.0012:,,,,,,,,,,,,,。[2]。,。,,2.102。,3.0023。。3)。2.10WGS-84。3.00,。。4)。:AN-TENNA:DELTAX/Y/Z(),ANTENNA:PHASE-CENTER。5)GPSGalileo。IQ,A,BC。,。tna[4]:t::C,L,D,Sn::1,2,…,8a::,I,Q:L1C:GPSGLONASSL1C/AGalileoCE2-L1-E1。C2L:GPSLL2C。Galileon,7E5b,8E5a+b。,。·53·2009.3/,:L2SL2。RINEX3.00GPS,Galileo,GlonassSBAS,1-4。1　RINEX3.00GPS(MHZ)GPSL11575.42C/AC1CL1CD1CS1CPC1PL1PD1PS1PZ-trackingandsimilar(ASon)C1WL1WD1WS1WYC1YL1YD1YS1YMC1ML1MD1MS1Mcodeless-L1ND1NS1NL21227.60C/AC2CL2CD2CS2CL1(C/A)+(P2-P1)(semi-codeless)C2DL2DD2DS2DL2C(M)C2SL2SD2SS2SL2C(L)C2LL2LD2LS2LL2C(M+L)2C2XL2XD2XS2XPC2PL2PD2PS2PZ-trackingandsimilar(ASon)C2WL2WD2WS2WYC2YL2YD2YS2YMC2ML2MD2MS2Mcodeless-L2ND2NS2NL51176.45IC5IL5ID5IS5IQC5QL5QD5QS5QI+QC5XL5XD5XS5X2　RINEX3.00Glonass/(MHZ)GlonassG11602+k＊9/16C/AC1CL1CD1CS1Ck=0～13or-7～+6PC1PL1PD1PS1PG21246+k＊7/16C/A(GlonassM)C2CL2CD2CS2CPC2PL2PD2PS2P3　RINEX3.00Galileo/(MHZ)GalileoE2-L1-E11575.42APRSC1AL1AD1AS1ABOS/CS/SoLC1BL1BD1BS1BCnodataC1CL1CD1CS1CB+CC1XL1XD1XS1XA+B+CC1ZL1ZD1ZS1ZE5a1176.45IOSC5IL5ID5IS5IQnodataC5QL5QD5QS5QI+QC5XL5XD5XS5X·54·GNSSWorldofChina/2009.3/(MHZ)E5b1207.140IOS/CS/SoLC7IL7ID7IS7IQnodataC7QL7QD7QS7QI+QC7XL7XD7XS7XE5a+b(AltBOC)1191.795IC8IL8ID8IS8IQC8QL8QD8QS8QI+QC8XL8XD8XS8XE61278.75APRSC6AL6AD6AS6ABCSC6BL6BD6BS6BCnodataC6CL6CD6CS6CB+CC6XL6XD6XS6XA+B+CC6ZL6ZD6ZS6Z4　RINEX3.00SBAS/(MHZ)SBASL11575.42C/AC1CL1CD1CS1CL51176.45IC5IL5ID5IS5IQC5QL5QD5QS5QI+QC5XL5XD5XS5X　　6)。RINEXsnrnx1～9.dBHz。snrnx=MIN(MAX(INT(snraw/6),1),9)7)(DCBs),RINEX。SYS/DCBSAP-PLIED,。2.2.2　观测值数据部分1):,snn,“”.。2),2.10。3)6。2.10PRN。3.00。。。F12.9F15.12。4)。,RINEX。RINEX3.005.·55·2009.3/5　RINEX3.002.3　3.00GPSGLONASS2.10,。3.00SBAS2.11GEO。6。6　SBAS·56·GNSSWorldofChina/2009.32.4　,“#/TYPESOFOBSERV”:、、,、。RINEX3.002.11,7。7　3　RINEX3.00RINEX3.00GPS,GLONASS,GALI-LEOSBAS,,,,RINEX3.00GNSS。GNSS。:,,,,RAIM,;,;[4];,;(),,,,(:GalileoL1,E5a,E5bE6GPSL1,L2,L5),、,[5]。RINEX3.00GNSS。GNSS:。::、、、;;;,[6]。:GNSS,;GNSS;,,:,;GNSS、、、、、,。:GNSS;、。4　　RINEX2.10,RINEX3.00,,GNSS,,GNSS,,、、·57·2009.3/。GNSS,RINEX,RINEX3.00。[1]　,,.[M].:,2007.[2]　WernerGurtner.RINEX:TheReceiverIndependentExchangeFormatVersion3.00[M].AstronomicalInstituteUniversityofBern,2006.[3]　,.GPS[M].:,2005.[4]　Tran,M.PerformanceEvaluationsoftheNewGPSL5andL2Civil(L2C)Signals[J].JournalofInsti-tuteofNavigation,2004,51(3):199-21.[5]　.GPSL2C[J]..2004,12(4):1～18.[6]　,,　.GPS[M].:,1997.NewGenerationofStandardDataFormat:RINEX3.00anditsApplicationGUShou-zhou1,2,BEIJin-zhong1,3,DANGYa-ming1,2(1.ChineseAcademyofSurveyingandMapping,Beijing,100039China;2.ShandongUniversityofScienceandTechnology,Qingdao,266510China;3.WuhanUniversity,WuHan430079China)Abstract:WiththemodernizationofGPSandGLONASS,thedevelopingofGALILEOandtheap-plicationofSBAS,thepositioningaccuracyandreliabilitywillbegreatlyimprovedbyuseofthecom-bineddataofthesesystems.Inordertoadaptforthenewfrequenciesandobservationtypes,anewRINEXversion3.00wasdevelopedbasedonRINEX2.ThepapermainlydiscussesthedifferenceofRINEX3.00andRINEX2.10andsimplyanalyzestheapplicationofRINEX3.00.Keywords:RINEX3.00;GPS;GLONASS;GALIELO;SBAS:　(1984-),男,山东菏泽人,山东科技大学与中国测绘科学研究院联合培养硕士研究生,主要研究方向GPS数据处理。·58·GNSSWorldofChina/2009.3
