[amsat-bb] Re: GPS Time observation
Well the most likely explanation would seem to be related to your GPS display routine. If you are getting accurate position information the timing from the satellites must be within a few nanoseconds. The satellite time currently differs from UTC by plus 15 seconds because UTC is retarded by one leap second on a regular basis but the satellite time is not altered. The satellites broadcast this offset from UTC but only every 12.5 minutes. It is not unusual for a GPS display to have a relatively low priority compared to the intensive position calculations and give a time display that differs by a second or two from UTC. 73 Alan ZL2BX -Original Message- From: amsat-bb-boun...@amsat.org [mailto:amsat-bb-boun...@amsat.org] On Behalf Of Dave Guimont Sent: Thursday, 2 February 2012 18:29 To: Vince Fiscus, KB7ADL Cc: amsat-bb@amsat.org Subject: [amsat-bb] Re: GPS Time observation Interesting question, Vince...am sure someone on here will be able to answer it.

[amsat-bb] Re: SatPC32 rotor question
I'll take a shot at this: You can, by SatPC32 settings, limit the movement to 90 deg elevation. That will prevent what many of us call "180 flip mode" or some variant. Now to limit to 85 deg?? I bet if you use a setting of either time interval (increase it...) or Position change (increase it) you'll end skipping most of the 85-90 operations, most of the time... Is it absolute? Probably not. Now, if the controller is configured to only go to 85 deg, I suspect it would ignore any values above 85...so just rely on the hardware/controller and not SatPC32. Best I can offer up... 73, Mark N8MH On Thu, Feb 2, 2012 at 12:36 PM, Dave Webb KB1PVH wrote: > I had this question posted to me, and I can't seem to figure out if it is > possible. > > >>.I want my rotator to stop at about 85 Deg elevation and not go to 90 , > 100 , 110 etc etc but to rotate on its asmith by >180 deg and then start to > drop elevation from 85 Deg.. > > I know that the rotor interface unit, ERC can be limited via it's service > tool software, but I wasn't sure how SatPC32 would react to the interface > unit limiting it. > > Dave - KB1PVH > ___ > Sent via AMSAT-BB@amsat.org.

Scott, No problem, unless you want to run it in full screen or graphics mode. WIN7 does not fully support DOS programs in full screen mode. However, there are a couple of ways around that. You can run it in a virtual XP machine. I have WIN7 Pro, and it is a free download. However, there is a simpler method. There is a program called DOSBox which is intended to run really old legacy games. It works perfectly with ITrack, and makes a much smaller footprint on your machine. http://www.dosbox.com/ Even though I have the virtual XP machine, I prefer to use the DOSbox version.

[amsat-bb] Re: GPS Time observation
You will find that most handheld GPS receivers sold for casual use have a displayed time error that varies from 0 to 4 seconds. The receiver software was designed with an emphasis on computing position and performing other tasks, such as routing, more than on displaying time. Hence the presentation of time is some times delayed. If time is of higher importance, then a specialized GPS timing receiver is needed. Look for one that outputs a 1PPS (one pulse per second) signal and comes with timing software.

[amsat-bb] Re: GPS Time observation
I'm not sure about GPS,but I have noticed that the clock on our cable box is off by up to 4 seconds at times.Customer service was not aware or concerned when I let them know. -Original Message- From: Vince Fiscus, KB7ADL Sent: Thursday, February 02, 2012 10:28 AM To: amsat-bb@amsat.org Subject: [amsat-bb] GPS Time observation I have an old GPS unit, a Magellan explorist 210. It's fairly accurate determining position. After it has acquired about eight to ten satellites the position error averages between 20 to 35 feet. Now the question, the other day I was looking at one of the information pages the unit can display and on it, it gives the time in UTC. Just for fun I thought I would see how close the time was to WWV. I was surprised to see the unit was between one to four seconds off over various tests compared to WWV. IS this typical of all GPS units or do some display the time of day more accurately? KB7ADL ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Re: GPS Time observation
Check outhttp://gpsinformation.net/main/gpstime.htm The short answer is, the internal GPS clock for position is very accurate or it could not make to calculations needed as to where you are at, but there are many factors that might delay what time it gives to you on a display panel or through a serial cable. 73 Kevin WA6FWF On 2/2/2012 7:28 AM, Vince Fiscus, KB7ADL wrote: I have an old GPS unit, a Magellan explorist 210.
