    2498 Each epoch in the output begins with a line containing the GPS Week Number and the seconds within the GPS Week. Following lines begin with the mountpoint string of the stream which provides the observations followed by a satellite ID. Observation types are specified by the 3-character observation code defined in RINEX Version 3. In case of phase observations a Slip Count is added which is put to '-1' if it is not set. The end of an epoch is indicated by an empty line.

     2503The following table describes BNC's synchronized output of GNSS observations via IP port. It consists of 'Epoch Records' and 'Observation Records'. Each Epoch Record is followed by one or more Observation Records. The Observation Record is repeated for each satellite having been observed in the current epoch. The length of an Observation Record is given by the number of observation types for this satellite. Secifications for code, phase, doppler and signal strenght follow definitions presented in the RINEX Version 3.03 documentation.
