FYI, the accuracy of GPS velocity should be around 5 cm per second for
the ublox GPS receiver, that is around 0.2 km per hour... So almost one
km/h is pretty bad... not necessarily TangoGPS fault. Maybe something is
badly configured in the GPS ship. Or maybe there is a sensible delay
between when the velocity is calculated and when it is displayed by
TangoGPS... Latency handling is very important in real-time navigation
software.
