     4555During the combination process BNC is waiting for clock corrections input epoch by epoch.
     4556BNC drops whatever is received later than 'Wait for full clock epoch' seconds.
     4557A value of about 10 seconds is recommended, depending on the latency of the incoming streams
     4558and the delay acceptable to your real-time GNSS combination product.

    45544563Specify a combination sampling interval. Orbit and clock corrections will be produced following that interval.
    4555 value of 10 sec may be an appropriate choice.
     4564A value of 10 sec may be an appropriate choice.
