Meteorological Data File : Pressure (mbar), Dry temperature (deg Celsius), Relative Humidity, Wet zenith path delay (millimeters)(percent)Įach file type consists of a header section and a data section.Navigation Message File : epoch, satellite clock information.Observation Data File : C/A code, P or Y code, L1 and L2 or Time, Phase, and Range.The RINEX version 3.00 format consists of three ASCII file types: RINEX Version 3 – The new version also includes the unofficial Version 2.20 definitions for space-borne receivers.RINEX version 2 – presented and accepted by the 2nd International Symposium of Precise Positioning with the Global Positioning System in Ottawa, 1990.RINEX version1 – presented and accepted by the 5th International Geodetic Symposium on Satellite Positioning in Las Cruces, 1989.Up till now two major RINEX format versions have been developed: 0: File sequence (Here it is first file of the day).335: Julian day or day of the year of first record (Date: ).The file structure of a RINEX file is as follows:Įxample: 04843350.13o(Observation file) and 04843350.13n(Navigation file) The GPS data in RINEX file format is universal acceptable as it is a receiver independent file format.
#Convert trimble t01 file to dat code#
L2 carrier waves (frequency 12.27 MHz, wavelength 24 cm) is modulated by P or Y code and navigation message. L1 carrier waves (frequency 1575.42 MHz, wavelength 19 cm) is modulated by C/A code, P or Y code and navigation message. DAT, T01, T02 as output file extension.Ī GPS signal consist of two carrier waves (L1 and L2) modulated with C/A code, P or Y code, navigation message. Since every manufacture is having its own proprietary output file format of GPS data collected. The proposal for RINEX was developed by the Astronomical Institute of the University of Berne, Switzerland. The first requirement for having a receiver independent exchange format arisen for easy exchange of the GPS data to be collected during the first large European GPS campaign EUREF 89, which involved more than 60 GPS receivers of 4 different makes.
