Hi All, I have a question. Does anyone have any suggestions on how to keep accurate time on the computer in an observatory that does not have internet...
... You'll need a clock disciplined by either a WWVB or GPS signal. There are expensive units that connect to your computer in various ways that can provide...
The canonical ways of doing this are radio receivers using GPS (or less often, GPS+WWV, Irig-B, etc) There are a wide variety of rackmount receiver units, most...
Here's the associated software that puts the time signals from the clock onto a local network: http://www.atomictimeclock.com/radsynhome.htm ... From: George...
Radio systems are nice, provided your observatory is in a zone where you receive radio signals… There are also some well written telescope control programs...
I think the set of area on the earth where amateurs have observatories and where GPS signals aren't available is very, very, small. I suppose if you were very...
I wrote a simple tutorial on using a USB GPS receiver last year: http://blog.retep.org/2012/06/18/getting-gps-to-work-on-a-raspberry-pi/ It would get you close...
I should ask a question we should have asked up front... What type of observatory is this, what's time going to be used for, to what precision (1 sec? 100 ms?...
Hi All, Sorry, I should have spoken about this in my first email. The observatory is located just outside Lubbock TX and belongs to the university. There is no...

Maybe I was not clear, GPS is available everywhere, but radio signal emitted by some stations are usually not available in remote places. In south America for...
