## 一、 THE PHILOSOPHY OF RINEX ##

Rinex格式起源于一个项目，需要将不同接收机的数据汇总归类，以方便处理：

一般Rinex格式数据包括：载波相位、伪距、信号观测时间。

The first proposal for the "Receiver Independent Exchange Format" RINEX has
    been developed by the Astronomical Institute of the University of Berne for
    the easy exchange of the GPS data to be collected during the large European
    GPS campaign EUREF 89, which involved more than 60 GPS receivers of 4
    different manufacturers. The governing aspect during the development was
    the following fact:
    
    Most geodetic processing software for GPS data use a well-defined set of
    observables:
    
    - the carrier-phase measurement at one or both carriers (actually being a
    measurement on the beat frequency between the received carrier of the
    satellite signal and a receiver-generated reference frequency).
    
    - the pseudorange (code) measurement, equivalent to the difference of the
    time of reception (expressed in the time frame of the receiver) and the
    time of transmission (expressed in the time frame of the satellite) of a
    distinct satellite signal.
    
    - the observation time being the reading of the receiver clock at the
    instant of validity of the carrier-phase and/or the code measurements.
    
    Usually the software assumes that the observation time is valid for both
    the phase AND the code measurements, AND for all satellites observed.
    
    Consequently all these programs do not need most of the information that is
    usually stored by the receivers:  They need phase, code, and time in the
    above mentioned definitions, and some station-related information like
    station name, antenna height, etc.

## 二、GENERAL FORMAT DESCRIPTION ##

Currently the format consists of four ASCII file types: 文件类型

1. Observation Data File  
2. Navigation Message File  
3. Meteorological Data File  
4. GLONASS Navigation Message File

## 三、 DEFINITION OF THE OBSERVABLES ##

Time、伪距/Range、Phase、Doppler术语在Rinex中表示的内容：

GPS observables include three fundamental quantities that need to be
    defined: Time, Phase, and Range.
    
    TIME:
    
      The time of the measurement is the receiver time of the received signals.
      It is identical for the phase and range measurements and is identical for
      all satellites observed at that epoch. It is expressed in GPS time (not
      Universal Time).
    
    PSEUDO-RANGE:
    
      The pseudo-range (PR) is the distance from the receiver antenna to the
      satellite antenna including receiver and satellite clock offsets (and
      other biases, such as atmospheric delays):
    
        PR  =  distance +
               c * (receiver clock offset - satellite clock offset +
                    other biases)
    
      so that the pseudo-range reflects the actual behavior of the receiver
      and satellite clocks. The pseudo-range is stored in units of meters.
    
      See also clarifications for pseudoranges in mixed GPS/GLONASS files in
      chapter 8.1.
    
    PHASE:
    
      The phase is the carrier-phase measured in whole cycles at both L1 and
      L2. The half-cycles measured by sqaring-type receivers must be converted
      to whole cycles and flagged by the wavelength factor in the header
      section.
    
      The phase changes in the same sense as the range (negative doppler). The
      phase observations between epochs must be connected by including the
      integer number of cycles. The phase observations will not contain any
      systematic drifts from intentional offsets of the reference oscillators.
    
    The observables are not corrected for external effects like atmospheric
    refraction, satellite clock offsets, etc.
    
    If the receiver or the converter software adjusts the measurements using
    the real-time-derived receiver clock offsets dT(r), the consistency of the
    3 quantities phase / pseudo-range / epoch must be maintained, i.e. the
    receiver clock correction should be applied to all 3 observables:
    
      Time(corr)  = Time(r)  -  dT(r)
      PR(corr)    =  PR(r)   -  dT(r)*c
      phase(corr) = phase(r) -  dT(r)*freq
    
    DOPPLER:
    
    The sign of the doppler shift as additional observable is defined as usual:
    Positive for approaching satellites.

## 四、文件的命名方式 THE EXCHANGE OF RINEX FILES: ##

We recommend using the following naming convention for RINEX files:
    
            ssssdddf.yyt      ssss:    4-character station name designator
                               ddd:    day of the year of first record
                                 f:    file sequence number within day
                                       0: file contains all the existing
                                          data of the current day
                                yy:    year
                                 t:    file type:
                                       O: Observation file
                                       N: Navigation file
                                       M: Meteorological data file
                                       G: GLONASS Navigation file
