资源简介:

Boxcar-integrated I&Q data sets of WWVB (60 kHz) received with magnetic loop antenna at 43.21N, 79.89W (Hamilton, ON). Three data files start at 09:00:00 UTC. on Aug 20, Aug 21, Aug 22, 2017. Each file spans seventeen hours. Each I&Q boxcar data point represents average WWVB carrier integrated over the one-second period starting with WWVB's BPSK phase-transition point, one-hundred milliseconds after start-of-second. The 60 kHz carrier downconverter oscillator is a Valpey-Fisher VF150 crystal oscillator which is free-running. Its phase and frequency vary with time and temperature. It is possible to determine WWVB's legacy AM timecodes from \(amplitude = \sqrt{inphase^2+ quadrature^2}\) File format is CSV text compatible, quadrature delimited by ASCII space '0x20' from in-phase. Quadrature and In-phase data are signed decimal integers lying in all four phase quadrants.
