-The latency of observations in each incoming stream is shown in the 'Latency' tab in milliseconds. Streams not carrying observations (i.e. those providing only broadcast ephemeris messages) are not considered here. +The latency of observations in each incoming stream is shown in the 'Latency' tab in milliseconds.

Note that latency calculations require the clock of the host computer to be properly synchronized.
