-gpsprof measures the various latencies between a GPS and its client\&. It emits to standard output a GNUPLOT program that draws an illustrative graph\&. It can also be told to emit the raw profile data\&. The information it provides can be useful for establishing an upper bound on latency, and thus on position accuracy of a GPS in motion\&.

 Other line latency
-The transmission latency between the GPS and gpsd not accounted for by RS232 time\&. Total line latency (the sum of this bar and RS232 time) is measured; it begins with the GPS sentence's timestamp and ends with a timestamp that gpsd generates at sentence\-reading time, before it is decoded\&.
