Introduction
This paper is a revised version of the one published by W. Gurtner and
G. Mader in the CSTG GPS Bulletin of September/October 1990. The main reason
for a revision is the new treatment of antispoofing data by the RINEX format
(see chapter 7). Chapter 4 gives a recommendation for data compression
procedures, especially useful when large amounts of data are exchanged
through computer networks. In Table A3 in the original paper the definiton
of the "PGM / RUN BY / DATE" navigation header record was missing,
although the example showed it. The redefinition of AODE/AODC to IODE/IODC
also asks for an update of the format description. For consistency reasons
we also defined a Version 2 format for the Meteorological Data files (inclusion
of a END OF HEADER record and an optional MARKER NUMBER record).
The slight modification (or rather the definition of a bit in the Loss
of Lock Indicator unused so far) to flag AS data is so small a change that
we decided to NOT increase the version number! In order to have all the
available information about RINEX in one place we also included parts of
earlier papers and a complete set of format definiton tables and examples.
The Philosophy of
RINEX
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.
General format description
Currently the format consists of three ASCII file types:
- Observation Data File
- Navigation Message File
- Meteorological Data File
Each file type consists of a header section and a data section. The
header section contains global information for the entire file and is placed
at the beginning of the file. The header section contains header labels
in columns 61-80 for each line contained in the header section. These labels
are mandatory and must appear exactly as given in these descriptions and
examples.
The format has been optimized for mimimum space requirements independent
from the number of different observation types of a specific receiver by
indicating in the header the types of observations to be stored. In computer
systems allowing variable record lengths the observation records may then
be kept as short as possible. The maximum record length is 80 bytes per
record.
Each Observation file and each Meteorological Data file basically contain
the data from one site and one session. RINEX Version 2 also allows to
include observation data from more than one site subsequently occupied
by a roving receiver in rapid static or kinematic applications.
If data from more than one receiver has to be exchanged it would not
be economical to include the identical satellite messages collected by
the different receivers several times. Therefore the Navigation Message
File from one receiver may be exchanged or a composite Navigation Message
File created containing non-redundant information from several receivers
in order to make the most complete file.
The format of the data records of the RINEX Version 1 Navigation Message
file is identical to the former NGS exchange format.
The actual format descriptions as well as examples are given in the
Tables at the end of the paper.
Definition of the
observables
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,
PR = distance + (receiver clock offset -
satellite clock offset) * c
so that the pseudo-range reflects the actual behavior of the receiver
and satellite clocks. The pseudo-range is stored in units of meters.
Phase
The phase is the carrier-phase measured in whole cycles at both
L1 and L2. The half-cycles meeasured 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
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: means 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
To exchange RINEX files on magnetic tapes we recommend using the following
tape format:
- Non-label; ASCII; fixed record length: 80 characters; block size: 8000
- First file on tape contains list of files using above-mentioned naming
conventions
When data transmission times or storage volumes are critical we recommend
compressing the files prior to storage or transmission using the UNIX "compress"
und "uncompress" programs. Compatible routines are available
on VAX/VMS and PC/DOS systems, as well.
Proposed naming conventions for the compressed files:
| System |
Observation files |
Navigation files |
| UNIX |
ssssdddf.yyO.Z |
ssssdddf.yyN.Z |
| VMS |
ssssdddf.yyO_Z |
ssssdddf.yyN_Z |
| DOS |
ssssdddf.yyY |
ssssdddf.yyX |
RINEX Version 2
features
The following section contains features that have been introduced for
RINEX Version 2.
Satellite Numbers
Version 2 has been prepared to contain GLONASS or other satellite systems'
observations. Therefore we have to be able to distinguish the satellites
of the different systems: We precede the 2-digit satellite number with
a system denominator.
snn
s: satellite system
blank: system as defined in header record
G: GPS
R: GLONASS
T: Transit
nn: PRN (GPS), channel number (GLONASS) or
two-digit satellite number
Note: G, R, and T are mandatory in mixed files
Order of the Header
Records
As the record descriptors in columns 61-80 are mandatory, the programs
reading a RINEX Version 2 header are able to decode the header records
with formats according to the record descriptor, provided the records have
been first read into an internal buffer.
We therefore propose to allow free ordering of the header records, with
the following exceptions:
- The "RINEX VERSION / TYPE" record must be the first record
in a file
- The default "WAVELENGTH FACT L1/2" record (if present) should
precede all records defining wavelength factors for individual satellites
- The "# OF SATELLITES" record (if present) should be immediately
followed by the corresponding number of "PRN / # OF OBS" records.
(These records may be handy for documentary purposes. However, since they
may only be created after having read the whole raw data file we define
them to be optional.
Missing Items, Duration
of the Validity of Values
Items that are not known at the file creation time can be set to zero
or blank or the respective record may be completely omitted. Consequently
items of missing header records will be set to zero or blank by the program
reading RINEX files. Each value remains valid until changed by an additional
header record.
Event Flag Records
The "number of satellites" also corresponds to the number
of records of the same epoch followed. Therefore it may be used to skip
the appropriate number of records if certain event flags are not to be
evaluated in detail.
Receiver Clock Offset
A large number of users asked to optionally include a receiver-derived
clock offset into the RINEX format. In order to prevent confusion and redundancy,
the receiver clock offset (if present) should report the value that has
been used to correct the observables according to the formulae under item
1. It would then be possible to reconstruct the original observations if
necessary. As the output format for the receiver-derived clock offset is
limited to nanoseconds the offset should be rounded to the nearest nanosecond
before it is used to correct the observables in order to guarantee correct
reconstruction.
Additional Hints
and Tips
Programs developed to read RINEX Version 1 files have to verify the
version number. Version 2 files may look different (version number, END
OF HEADER record, receiver and antenna serial number alphanumeric) even
if they do not use any of the new features
We propose that routines to read RINEX Version 2 files automatically
delete leading blanks in any CHARACTER input field. Routines creating RINEX
Version 2 files should also left-justify all variables in the CHARACTER
fields.
DOS, and other, files may have variable record lengths, so we recommend
to first read each observation record into a 80-character blank string
and decode the data afterwards. In variable length records, empty data
fields at the end of a record may be missing, especially in the case of
the optional receiver clock offset.
RINEX under antispoofing
(AS)
Some receivers generate code delay differences between the first and
second frequency using cross-correlation techniques when AS is on and may
recover the phase observations on L2 in full cycles. Using the C/A code
delay on L1 and the observed difference it is possible to generate a code
delay observation for the second frequency.
Other receivers recover P code observations by breaking down the Y code
into P and W code.
Most of these observations may suffer from an increased noise level.
In order to enable the postprocessing programs to take special actions,
such AS-infected observations are flagged using bit number 2 of the Loss
of Lock Indicators (i.e. their current values are increased by 4).
