It would be nice, but if no graphic i/f is used for the server side, I think it would be better to implement it in standard C instead of PyQt, for portability reasons, so the server could be easily rebuilt for running in a non-PC class embedded linux computer (like those using ARM) For providing ntp, probably the best way is to use ntp :) As far as I remember, since I've not played around it since some time, the LinuxPPS driver is implemented as a character driver, so several applications can read it, and as other has pointed, ntp i/f to the GPS can be implemented using shmem. ntp can also be recompiled for running in almost anything (I've put it into work both in Nios-II uClinux-MMU and Blackfin uClinux-nonMMU, also taking time from an M12 using Linux-PPS) Best regards, Javier ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

I patched it and wrote some startup and monitoring scripts for it for Ubuntu. See http://wa5znu.org/2011/08/tbolt/ I run Heather under Wine with some flags and make it talk to the server; that cuts way down on the CPU time that LH would otherwise use in its tight loops.

[time-nuts] Lady Heather for a noob
Alright, I took the plunge and got a Thunderbolt and installed Lady Heather 3.00. So, it first didn't seem to want to grab satellites, probably because it had a position set in it of 23.1019557 113.2662616 which looks to be a tall building in China. I used Google Earth to get a lat/long which was as accurate as I could make it and put those in. That gained me 4 good and 4 marginal satellites and phase lock. What should I do next? Should I have it do its own survey? Do I need to change any settings from default? Do those readings, or some others, tell me when I'm fully up and synchronized? Is there a faq on how to do this that someone could point me to? Any help would be much appreciated!

Re: [time-nuts] Lady Heather for a noob
For normal use all you need to do is apply power. You don't need to connect a computer at all. The t-bolt will figure out it's location and be up and running in maybe an hour. LH is for the next step where you care about fine running. Now it's maybe better to just let it run Sounds like you might have a marginal antenna. It really does need a good view of the sky and the self survey is not useful if the antenna can move, so at least duct tape it down. A mast is better. Have to read the Thunderbolt book http://www.trimble.com/support_trl.asp?pt=Thunderbolt®%20GPS%20Disciplined%20ClockNav=Collection-2357 the monitor program at the above link is less complex and a good way to get started. Now, to hijack this thread. Do people think a server version of LH that does NOT need Windows would be usefull. Sames a water to have to find a Windows PC just for this one task. The server could run on a very low-power computer and push data onto the network. For example I have the t-bolt running an NTP server and I'd like to run the LH server on the same computer On Thu, Jan 12, 2012 at 7:24 PM, Peter Gottlieb n...@verizon.net wrote: Alright, I took the plunge and got a Thunderbolt and installed Lady Heather 3.00.

Re: [time-nuts] Lady Heather for a noob
To original poster - go to bed, let it sit and see what you have tomorrow. Chances are it will be locked on 8 birds and settled down. I found the KE5FX remote link very useful as a reference system in learning about LH. I think I hosed up that machine pretty good in the learning process too (sorry to all). Hijacked thread. Yes - this would be great to see done on a linux machine.

brent.ev...@gmail.com said: I don't know much about NTP other than pointing machines to NTP servers for time, but having the server side provide also be an NTP server would be the cats ass for me. I think the way to do that would be to make LH use the shared-memory interface to NTP. (Contact me off list if anybody wants more info. Or look at the gpsd sources.) Or maybe setup NTP to watch the PPS API too. I'm not sure what happens if 2 programs are both reading the PPS API and/or if that's what LH uses so this could be a wild goose chase. -- These are my opinions, not necessarily my employer's.
