-<p>BNC can average the latencies per stream over a certain period of GPS time. Mean latencies are calculated from the individual latencies of at most one (first incoming) observation per second. Mean latencies are recorded in the Log file/section at the end of each 'Latency logging' interval. Select a 'Latency logging' interval or select the empty option field if you do not want BNC to log latency information. Note that computing correct latencies requires the clock of the host computer to be properly synchronized.

+<u>Statistics:</u> BNC counts the number of GPS seconds covered by at least one observation. It also estimates an observation rate from all observations received throughout the first full 'Performance logging' interval. Based on this rate, BNC estimates the number of data gaps when appearing in subsequent intervals.
