He built a WWV receiver and worked with NIST to get estimates of propagation delays to get his best time estimate.

And since female albatross lay only one egg a year but take about that much time to incubate and raise their young, Peterjohn estimated that Wisdom has likely raised as many as 30 to 35 chicks. He noted that the the U.S.

I'll use 8' as a good estimate. I'm also not going to consider tide swing - but that has a pretty small effect with 200' of chain. First we have to determine the maximum amount of swing that you can actually experience.

FFT magnitude squared bin, is a rather hand-wavey approach to estimating receiver characteristics, but it's the "easiest" and hence, somewhat comparable, approach to giving you an estimate.

From that, read/estimate max output power at given freq and gain (5 dB: ca -10 dBm, 25 dB: ca 10 dBm) 3. Estimate TX output power (5 dB -> -10dBm · 0.2 ampl: ca -24 dBm, 25 dB -> 10dBm · 0.8 ampl: ca 8 dBm) 3. Estimate power reaching the TwinRX (5 dB/cable: -10 dBm·attenuation; 25 dB/antennas: ca +8 dBm · antenna gain · path loss) 3.

Estimates of classical measures such as the mean and standard deviation from the samples diverge as the number of samples increase. Whilst attempts have been made to estimate the error due to deadtime, the corrections require that the phase noise characteristics of the 2 (or more) sources being compared are accurately known.

Hi, There is two types of errors done when using this type of counters, First, the delta-estimator of frequency filtering will skew the Allan deviation, mostly in the white phase noise region but the effect wears of at the length of the averaging windown of the counter.

The result is rather disappointing (at least wrt my expectations): attached is the plot of the delay estimate between X310 channels from the PRN * when adding the GNSS antenna output (blue chart), the time transfer capability is degrated from a few ps to 1 ns (standard deviation).
