Re: [time-nuts] nuts about position (Michael Wouters)

Real-time GPS <0.3m accuracy is quite possible with RTKLIB and < $35 of new equipment, some patience, a laptop/android phone, and a real-time RTCM3 correction station stream (free) or with post-processing using ground stations and actual satellite path (Ephemeris). Disclaimer: I am neither a

Re: [time-nuts] Very Accurate Delta Time RF Pulse

Thank you all who responded including Bob, Attila, Vlad, Brooke, and Chris for some great suggestions. This is a fun side project of mine to passively detect RF emitters based upon strongest nearby signal using ToA pulses from cheap log power sensors or perhaps the Watson-Watt method. The

[time-nuts] Very Accurate Delta Time RF Pulse Measurements

Hi Guys, This is a little outside of time-nuts scope, but not by much. I'm interested in finding the time between two rising edges above a set threshold with preferably nS or high ps timing accuracy. Can this be simply done with a few programmed Microchip PICs or with a good short term OCXO

[time-nuts] FTS 4050 Cesium Time Reference Manual

Does anyone by chance have a copy of the FTS 4050 Cesium Time Reference Operation or Service manual in PDF? Or is an equivalent Cesium unit out there who's manual can be used as a surrogate for setup and operation? I have a request in with support from Symmetricom (Microsemi), however there is

[time-nuts] Generating a solid PPS from 10Mhz source

Hey Guys, Is there an easy circuit to build that can consistently deliver a 1 PPS from a 10MHz source with excellent resolution and repeatability? My first application is to test different 10MHz oscillators without a TIC always attached and then compare the PPS output change over time against
