What needs to gpsd for compute of speed?
two Time and Position Pairs.  speed = (p2 - p2) / (t2 - t1)

If that were true then gpsd would return the speed by GGA sentences only.
But I don't observe it. If I send to the gpsd only a GGA sentences (from real NMEA log, without changes) - gpsd doesn't return a speed.
