Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. Is it the position of the receiver antenna or the satellite? The coordinates are defined by WGS These coordinates are typically extracted from the raw data file downloaded from the receiver when the RINEX file is created.

However, these coordinates can be modified by the user at the time of creation. Typically the position is of psuedorange quality don't rely on it for precise applications. You are probably looking for S1 signal-to-noise for L1 and S2 signal-to-noise for L2. If more than 5 types are present for a given epoch and satellite, then they will be continued on the next line. If S1 or S2 are not present in the file, then you are out of luck if you don't have access to the raw data file.

RINEX simply provides the raw observables from each satellite that are used to compute positions. If all you care about is the Approx. There are many utilities available to do that. For an example check out OPUS. Most support static processing, some support kinematic processing. Well let's just say that when you process RINEX data to obtain position estimates, there are all sorts of error sources that must be accounted for a user to obtain accurate position estimates. If you're interested, check out books like Global Positioning System: Signals, Measurments, and Performance for more information.

There are a few free tools out there. GPSTK also has utilities that help with that. Learn more. Asked 5 years ago. Active 5 years ago. Viewed 4k times.Since every manufacture is having its own proprietary output file format of GPS data collected. For example Trimble have. DAT, T01, T02 as output file extension. L1 carrier waves frequency L2 carrier waves frequency 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 for each line contained in the header section. Each Observation file and each Meteorological Data file basically contain the data from one site and one session.

Starting with Version 2 RINEX also allows to include observation data from more than one site subsequently occupied by a roving receiver in rapid static or kinematic applications. Although Version 2 and higher allow to insert header records into the data field it is not recommended to concatenate data of more than one receiver or antenna into the same file, even if the data do not overlap in time.

If you choose, your position can also be shared publicly on the NGS website. NGS will publish the coordinates on survey mark datasheets. OPUS decimates all recording rates to 30 seconds.

Select your antenna type To find the correct antenna type, browse antenna calibrations. Correctly selecting your antenna will help OPUS apply the appropriate antenna calibration model to counter the unique measurement biases inherent in each antenna's design.

Choosing an incorrect antenna may result in a height error as large as 80 cm and a horizontal error up to 1 cm. See antenna calibration for a drawing of the ARP for your antenna usually the center of the base or tripod mount. Depending on the duration of your data file, OPUS will use either static or rapid-static processing:.

Under normal conditions, most positions can be computed to within a few centimeters. However, estimating the accuracy for a specific solution is difficult because formal error propagation is notoriously optimistic for GPS reductions.

User errors such as misidentification of antenna or ARP height cannot be detected. Local multipath or adverse atmospheric conditions may also negatively impact your solution. Please note: OPUS-RS may perform poorly or fail during periods of high ionospheric disturbance or during the passage of a strong weather front.

In general, it is best to avoid collecting GPS data during these events. Extended: in addition to the information in the standard solution, the extended solution also includes more detailed information about the base stations used and solution statistics.

For static: The formal statistical root mean square RMS error of your solution.

For rapid static: a unitless normalized RMS. Accuracies below are reported as either peak-to-peak errors static or standard deviation estimates rapid static. All initial computations are performed in IGS. Your NAD83 coordinates are derived by transforming IGS vectors into the NAD83 reference frame and recomputing the 3 independent and averaged positions not a direct transformation of the IGS coordinates; a direct transformation could be considered more accurate, but wouldn't fit your surrounding NAD83 network as well.

Your final IGS reference frame coordinates retain this observed epoch, while your NAD83 coordinates are transformed again to the standard epoch date of January 1, The US National Grid coordinates and referenced datum are reported, if applicable.

I got a warning message that the IGS Precise Orbit was not available at the time of processing, but the "rapid" was used. What does that mean? This final precise orbit is the combination of seven analysis centers worldwide.

It can take these analysis centers several days to upload the orbit to the IGS so the availabilty of a Sunday orbit can be 19 days.If enabled, data is scanned after conversion to correct potential issues. See Pre-processing Checks for more information. Auto will set the entire file static or kinematic according to the detected processing environment.

The default value is 0 cycles, as most manufacturers remove the offset at the firmware level, but this is not always the case. The decoder attempts to determine the data interval by reading the header or scanning the observation file. If this fails, enable this option to force an interval.

Setting the interval here may be required for successful conversion of RINEX data that contains data gaps in the first minute of the file.

This is because data gaps early in the file may cause errors computing the expected data interval. Calculates Doppler from the change in L1 phase measurements between consecutive epochs. This will produce average velocity values between measurement samples that are relatively noisy.

Recomputes Doppler using predicted satellite motion from the broadcast ephemeris. This requires the data to be static and is the best method for recomputing Doppler data for static data. If a navigation file is either missing or has a different name than the observation file, you will be prompted to select a navigation file. You may define a path to the navigation file manually.

This will override the previous option. The yy in the file extensions found in the table above designate the last two digits of the year that the observations were collected in. OM v5. January Waypoint User Documentation. Skip To Main Content. All Files. Submit Search. You are here:.

OPUS: Online Positioning User Service

To get the geolocation of connected GNSS chips. An independent computation to check and validate positions from a real-time positioning process. Our innovative products are conceived to have an adaptability level the current wide-scope solutions would not reach. Stop using GNSS pivots and go for virtual reference stations. Allow your material and human resources somewhere else! Thanks to our high-quality geodetic algorithms, get precise coordinates even within a low CORS-density area.

You have no choice but record a short session instead of a long one as the state-of-the-art requests? You can use them to get precise coordinates even with short observations range! Set virtual reference stations to simulate a balanced CORS network around your points network. Shorten your measuring time! With the PPP algorithm, the positioning accuracy is enhanced in the whole world.

GNSS chips embedded in your systems may be located from the meter to the centimeter level! In the file, for each recorded epoch, there is a list of the available observables value, especially the code and phase value, for every tracked satellite at the recording time. Those values are used as distances between the satellite and the receiver.

The raw data written in a RINEX file can be used for several tasks, such as coordinates computation, ionospheric or tropospheric activity surveys, GNSS antennas calibrationand more. A RINEX file is called virtual when raw data have not been really measured by a receiver but have been computed. The virtual data are derived from surrounding CORS observations thanks to interpolation methods. It is then possible to simulate a CORS right on your working location!

It is so much easier to make a precise georeferencing of your GNSS receiver. The baseline between reference station and rover is as short as possible.
