     2614<p>A valid 'Lock Time Indicator'
     2615An optional valid 'Lock Time' is only presented for observations from RTCM Version 3 streams. The parameter provides a measure of the amount of time that has elapsed during which the receiver has maintained continuous lock on that satellite signal. If a cycle slip occurs during the previous measurement cycle, the lock time will be reset to Zero. The 'Lock Time' could be of interest becuase the Lock Time Inficator is different for different RTCM3 measurement types. Hence, the 'Lock Time' in seconds is computed with the respective calculation rule.

     2617
    26142618<p>
    26152619The following table describes the format of BNC's synchronized output of GNSS observations which 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.
