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.

Tick 'Auto start' to supersede the usage of the 'Start' button. The information is recorded in the specified 'Raw output file' in the received order and format.
It supports the offline repetition of a real-time situation for debugging purposes and it is not meant for Post Processing. BNC adds its own time stamps in order to allow the reconstruction of a recorded real-time situation. The default value for 'Raw output file' is an empty option field, meaning that BNC will not save all raw data into one single daily file. In case an observation type is listed in the RINEX header but the corresponding observation is unavailable, its value is set to zero '0.
The solution implemented in BNC is to start with RINEX Version 3 observation type records from skeleton files see section 'Skeleton Extension' and switch to a default selection of observation types when such skeleton file is not available or it does not contain the required information.
Specifying a decoder string 'ZERO' means to not convert the affected stream contents but save its contents as received. If there is more than one stream with identical 4Char Station ID same first 4 characters for their mountpoints , the mountpoint strings are split into two sub-strings and both become part of the RINEX file name.
If several streams show exactly the same mountpoint name example: BRUS0 from www. The default value is 15 minutes. This is the default value. A HTTP link to a directory containing these skeleton files may be available through data field number 7 of the affected NET record in the source-table.
For that BNC allows using personal skeleton files that contain the header records you would like to include. You can derive a personal RINEX header skeleton file from the information given in an up to date sitelog. If that is overridden by a stream outage, the triggering event is the stream reconnection. The default value is 1 day. Specify an IP port number to activate this function. Galileo multipath plots are presented for L1 and L5 frequencies.
BNC lets you specify the RINEX version, sampling interval, begin and end of file, operator, comment lines, and marker, antenna, receiver details. Default is an empty option field, meaning that no additional comment line will be added to the RINEX header.
When specifying several input files BNC will concatenate their contents. If 'Analyze' is selected, specifying a 'Log' file to output analysis results is mandatory. A multipath and a signal-to-noise ratio analysis are presented in terms of a sky plot. The syntax for that looks as follows --key where stands for the name of an option contained in the configuration file and stands for the value you want to assign to it.
The following example for a Linux platform calls BNC in 'no window' mode with a local configuration file 'rnx. This approach to differential positioning is using 'observation space' information.
An alternative to the observation space approach is the so called 'sate space' approach. The principle here is to provide information on individual error sources. For a rover position, state space information concerning precise satellite clocks, orbits, ionosphere, troposphere et cetera can be converted into observation space and used to correct the rover observables for more accurate positioning. Alternatively the state information can directly be used in the rover's processing or adjustment model.
RTCM has developed Version 3 messages to transport satellite orbit and clock corrections in real-time. When using clocks from Broadcast Ephemeris with or without applied corrections or clocks from SP3 files, it may be important to understand that they are not corrected for the conventional periodic relativistic effect.
Orbit corrections are provided in along-track, cross-track and radial components. These components are defined in the Earth-centered, Earth-fixed reference frame of the broadcast ephemerides. For an observer in this frame, the along-track component is aligned in both direction and sign with the velocity vector, the cross-track component is perpendicular to the plane defined by the satellite position and velocity vectors, and the radial direction is perpendicular to the along track and cross-track ones.
The three components form a right-handed orthogonal system. After applying corrections, the satellite position and clock is referred to the 'ionospheric free' phase center of the antenna which is compatible with the broadcast orbit reference.
Depending on the accuracy of your application you should correct for such effects by other means. Such messages are needed for accurate single frequency applications. Broadcast Corrections can be saved by BNC in files. The file name convention for Broadcast Correction files follows the convention for RINEX files except for the last character of the file name suffix which is set to "C".
Saved files contain blocks of records in plain ASCII format where - separate for each GNSS, message type, stream, and epoch - the begin of a block is indicated by a line like examples :! In case of RTCM message types or see Annex the first five parameters in each record are followed by Number of Code Biases Indicator to specify the signal and tracking mode Code Bias Indicator to specify the signal and tracking mode Code Bias etc. Default value for Broadcast Corrections 'Directory' is an empty option field, meaning that no Broadcast Correction files will be created.
The default is an empty option field, meaning that no Broadcast Correction output via IP port is generated. The output format equals the format used for saving Broadcast Corrections in a file with the exception that the Mountpoint is added at each line's end. A value of 2 to 5 seconds could be an appropriate choice for that, depending on the latency of the incoming Broadcast Corrections stream and the delay acceptable by your application.
