It is based on phase-lock techniques. Al its narrowest bandwidth, 0.03 cps, the phase peak-topeak noise deviations are reduced to ± 1.5 percent of a wavelength for a signal strength of -140 dbm coming into the receiver "front ends". The filter introduces no phase shift or time delay regardless of the signal phase rate.application/pdfenginfo:eu-repo/semantics/openAccessTracking control systemsArtificial satellitesLocation and trackingA phase-locked phase filter for the minitrack systeminfo:eu-repo/semantics/reporthttp://purl.org/pe-repo/ocde/ford#1.05.01
