I'm working on some GPS tracking apps on Android tablets. We found out that depending on the type of phone / tablet we use, we can have results ranging from really accurate to really bad.

Those tests were conducted on the same track, with GPS only location - so I'm pretty sure the GPS chip quality is of great importance in those results differences.

Is there any way to access GPS chips manufacturers or infos depending on device models ? An app, command ... any means.

  • Hmm I forgot to add in my question that we're only working with android devices. That's why I posted here. Sorry for the oversight. Question edited. – Mat Apr 23 '15 at 7:07
  • Looks OK to me, I see no reason that an end user couldn't be interested in the model of their GPS chip. I have removed the request for an off-site resource or programming solution since those are off-topic. You could ask on Stack Overflow about a way to use code to get this info -- just link to this question and point out that it differs in approach. – Matthew Read Apr 23 '15 at 12:20
  • Thanks for letting me in. I finally found some informations. The thing is, I had trouble to find it because I didn't know nowadays the GPS module is embedded with cpu / gpu / ... whereas I was looking for standalone modules. Anyway I started a list myself (see answer). – Mat Apr 23 '15 at 13:01
  • I do a lot of work with GPS systems and antenna gain, placement and general design plays a huge part. Sleep / low power modes that can be changed in low-level software / firmware can also affect instantaneous accuracy so this generally might be a bit more complex than assuming one chipset is more accurate than another. – PeterJ Apr 23 '15 at 13:38
  • Thanks @PeterJ for your interest. Any luck you'd share some resources on the subject ? My list is just a starting point I guess, but I'm really new on the subject. – Mat Apr 23 '15 at 15:10

I didn't find anything up to date over the internet.

Thing is : nowadays gps modules in mobile devices get embedded with other components such as gpu / cpu / wifi receiver / ....

So what you have to do is googling for "cpu details Galaxy Tab 10.1" for example, and then see what's included in this particular kind of chip.

Anyway I started a list for my own personal use, feel free to use / amend it : https://github.com/mhicauber/android-devices-gps-chip-manufacturers
