Hi, I would like to add sbas data to my stand alone solution, using ublox lea-4t receiver. the raw data i know how to get from the gps receiver, but i was unable to find how to ask for the sbas ephemeris. dose someone knows at which massage are they? assuming it is possible having the sbas ephemeris, does some one knows

I have such a receiver, but the led doesn't start flashing / doesn't go on, when I insert it in a ps/2 to usb cable or I insert it in a PS/2 socket of a computer. Is that normal?? -- -- 700+ Radio Stations on SW http://swstations.tk/

Just curious - last week on Tuesday my Garmin 765T went deaf for satellites while in the middle of a journey. Powered it down at the end of the journey, left it a few hours and it was ok for the return trip. Curiously, later that evening I discovered that it had flattened its battery. Charged it up and copied the current.gpx to my laptop. The next day, it went deaf again shortly after starting...

Apologies in advanced if this has been asked before! Having always thought SatNavs were just for people who couldn't read maps I have now come back down to earth and realised that I need one. The choice has left me bewildered. Can anyone recommend any decent and unbiased online reviews or comparisons that would help me make my choice? I do not want to subscribe to any subscription services as I...

Read the article I wrote on the SVN 49 issue. It is out on the Inside GNSS "frontpage" (http://insidegnss.com) now and will be included in the July/August printed version The article nicely shows and explains what is being done and why that works (for "ordinary" users).

Could anyone please let me know the definition of "Observed minus Computed" DD PSR and "Observed minus Computed" DD Carrier Phase? Is there any difference between the term "Observed minus Computed" and "Observed minus Expected"? Thank you.

I am using Anquet mapping software on my Asus A696 PDA. In general I find this very useful. However, the issue I have is that when I am walking slowly my actual and displayed position can be lagged by as much as 150 metres. I understand that this is a feature known as Static Navigation. A search of the web suggests that SirfTech software can be used to toggle this off and on.

Here is another take on Friday's meeting. http://blogs.agi.com/navigationAccuracy/ "Question: How is the fix for this problem modeled? Is it a constant bias or something else? Answer: (Madden) The fix effectively moved the antenna phase center for the satellite to 150 meters behind the satellite.

Does anyone have a copy of the Rocanda Grid Map they'd like to share? I would order it myself, but I don't have a credit card, and there is no nearby retail outlet where I can purchase it in person. Your post of the map would be most appreciated. Thanks

"I have used Streets & Trips 2009 in Mexico a lot. I've used it in the following states: Tamaulipas, Veracruz, Coahuila, Chihuahua, Sonora, Sinaloa, and Durango. Generally I'd say it has very good coverage from major roads down to small pueblos. Perhaps the biggest limitation is when you try to map along the autopistas, especially the newer ones. For instance, you can't map a trip from...

Routine early orbit checkout procedures determined that GPS IIR-20(M) signals were inconsistent with the...

I'd like suggestions from experienced users on GPS data loggers for photography. Oddly my Sony a900 does not come with a GPS data input to tag images with position and time. I would have though Sony would have added this as a natural with their own GPS logger. (Sort of proves the ex-Minolta guys are keeping their distance from the gadget boys at Sony). IAC, I would like a logger that:

The U.S. military's newest Global Positioning System navigation satellite is suffering from unusual signal distortions that will keep it out of service for at least six months, the Air Force announced Tuesday.

I am struggling to decide on a sat nav for a truck here in the UK.

Good morning all.

Hello there, Is this possible (as the title says) as a GPS receiver? I don't know much about GPS' NMEA but apparently on the setup page in MapPoint requires a 2.0 of NMEA. How do I check if this is possible? Thanks in advance, Lu Zheng

http://www.lazygranch.com/temp/infodia1.jpg http://www.lazygranch.com/temp/infodia2.jpg I got this at a flea market. The company appears to be defunct. It may be a GPS with some other functions since it has a SMA on the back, presumably for the external antenna. Any information on the device would be appreciated.

I have a Nuvi 765T and was wondering whether it is possible to tailor the typical road speeds it uses when working out routes and ETAs. Or even just to assign preference weights to certain types of road. I do find that it is often quite optimistic about ETAs early in the journey, having to re-adjust them later on, particularly if the traffic is slower than the speed limit. It appears to expect...

So far it seems to be an improvement. It was easy to install too, unlike my past adventures with Garmin's unlock codes. The NT seems to take up a lot less space on the memory than did my old non-nt 2007 City Select map. Garmin is being very coy with the update year on the package. No place does it say 2010, so people won't know if they are buying a 2009 or 2010, and so I guess so they can...

I've just bought one and I think it's great. Have a look at www.a-trip.com to see what you can do with it. They also give away free software for Windows mobile devicses to do the same sort of thing using the mobile device's inbuilt GPS or a separate GPS receiver.
