<p dir="ltr">I've seen these work well.  Cheaper at other sources.   No 10mhz but does 1pps.  Ymmv.. </p>

<br>
These were designed as a retrofit for a specific earlier GPS receiver but they appear to be potentially useful to supply at least the 1 PPS signal required by the RTCM.  They might also act as a frequency standard for simulcast, although they may not have the oscillator required to provide a stable frequency source in the event of loss of GPS signal.<br>
<br>
Does it appear that these units would work? Has anyone experimented with this or similar units with the RTCM?<br>
<br>
Thanks.<br>
