Talk:Automotive navigation system

From Wikipedia, the free encyclopedia

Blurb on taxis would be more appropriate in taxicab or mobile data terminal.

[edit] Contributions regarding mobile phones gps navigation system

I'd like to contibute to this subject, I work for LocatioNet who makes amazegps.com. Can I do it by myself or is it inappropriate? Thanks. Yoavf 07:41, 15 April 2007 (UTC)

see TomTom and Garmin for examples. remember to use a neutral informative format. Stephen Charles Thompson (talk) 06:32, 6 June 2008 (UTC)

[edit] CARiN

There seems to be too much emphasis on CARiN, which is a proprietary map database format. None of its inner structure or methodology is discussed, so the treatment of it has limited value. Roesser 16:28, 5 August 2007 (UTC)

[edit] DIY GPS receiver

GPS-receivers can also be build yourself. Please take a look at DIY GPS receiver and perhaps include in the article. —Preceding unsigned comment added by 81.245.186.7 (talk) 16:23, 9 October 2007 (UTC)

[edit] Better picture?

Who cares if it's in a taxi, let alone in Kyoto? We should take a picture of a satnav. Currently if readers don't already know what it looks like they would be excused for not being able to figure it out. Thanks. 83.67.217.254 (talk) 19:21, 9 December 2007 (UTC)

[edit] Dead Reckoning on Portable GPS Units (Dispute)

Resolved. Error addressed in dead reckoning portion of portable GPS units

Medic48 Medic48 (talk) 03:28, 26 January 2008 (UTC)

This part of the article indicates that portable GPS units do not have dead reckoning available, however in the TomTom 920, it has an EPS module that uses dead reckoning to identify position. What is Enhanced Positioning Technology (EPT). Retrieved on 2007-12-22. Medic48 (talk) 23:10, 22 December 2007 (UTC)

The article talks about GPS systems that have speed, direction and acceleration sensors, that allow for very accurate, unambiguous dead reckoning. Most portable GPS, not having any of these external inputs can only use dead reckoning in a very limited way, i.e. when speed and direction remain constant, and the vehicle continues to travel on the same road. However it appears you are correct in stating that the TT920 has motion sensors that now bring some of these features to handheld devices too (presumably it needs to be mounted to the vehicle rather than being held in your hand to work though?). Anyway, the article needs an update to clarify this development... Socrates2008 (Talk) 23:26, 3 January 2008 (UTC)

[edit] BMW uses VxWorks and *NOT* Windows

All current BMW iDrive systems use VxWorks on a 32-bit Hitachi SH processor. It even states so on the iDrive page.

The very first iDrive system in a 7-series did indeed use WindowsCE. It might have also been briefly used in a 5-series, but it was never used in the 3-series and all current BMWs use VxWorks for iDrive. —Preceding unsigned comment added by 81.165.3.128 (talk) 22:38, 3 January 2008 (UTC)

[edit] Primacy Dispute

I've added a lot to the section discussing who was first with automotive navigation systems. I think "commercially available" is an appropriate way to qualify the debate, since there were automotive navigation efforts conducted for basic research purposes somewhat earlier, and that doesn't seem to be an area of dispute. My NPOV might be suspect, since I was a consultant at Etak in 1989. I've done some work on both the Electro Gyrocator article and the article on Etak. —Preceding unsigned comment added by Yakushima (talk • contribs) 09:56, 18 April 2008 (UTC)
