 The latency of observations in each incoming stream is shown in the 'Latency' tab in milliseconds or seconds. Streams not carrying observations (i.e. those providing only broadcast ephemeris messages) are not considered here. Note that the calculation of correct latencies requires the clock of the host computer to be properly synchronized.
