I recently purchased a Garmin GPS 18 LVC for the purposes of a refclock. After soldering all the wires to a 9-pin serial connector and getting power from a USB port, I connected it to my Windows machine and used the Garmin SNSRCFG software to test it out. To my surprise it had locked on to 8 satellites, and currently seems to vary anywhere from 3 to 10. I had plans to mount it outside a window or possibly on the slope of the roof, but from the looks of it now I can leave it sitting on top of my Linux machine where it is currently connected, with the 5 meter cable still coiled up in a twist tie. I don't have any long-term data yet, as it's only been two days, but so far it works great. Offsets average about +- 15 us, and jitter and noise are in the 1-2 us range. So you might try the GPS 18 LVC as you just might get good signal, even indoors like mine. -- Dennis Hilberg Jr <timekeeper(at)dennishilberg(dot)com> NTP Server Information: http://saturn.dennishilberg.com/ntp.php _______________________________________________ questions mailing list questions@lists.ntp.org https://lists.ntp.org/mailman/listinfo/questions
