I am in the market for a simple GPS module to integrate with my current autonomous robot and am looking for recommendations. I know working with GPS indoors is always hit or miss (most often miss). Can anyone suggest a GPS module that might have a decent chance of working under inside conditions?
u-blox. They are expensive but work very well under adverse conditions. They are used by the military and law-enforcement agencies because of their performance.

Do you have first hand experience with u-blox?
I’ve used one of the earlier units; it worked very well, and support was good. That should do what you want.

I’ve used that module. It has the LEA-5H GPS module and the
helical antenna. I’m not sure if it is the antenna or the chipset
but it locks onto several satellites buried in my office that has
no windows and is in the center of a large building. None of my
various GPS handheld and USB units will lock even a single satellite.
I was amazed that it was able to do that.
This module has a NEO u-Blox module but no antenna:
Wow, that’s impressive. How do you feel about it’s position accuracy? Knowing this is hard to quantify, is it roughly within 5m?
I’ve not done any testing or checking of it’s accuracy yet from firsthand experience, but I have read that it is very accurate compared to other
GPS modules. I’ll know more in about 30 days.
Something tells me you are going to be dissapointed even with a really powerful gps unit. What type of accuracy are you expecting/need?
Yep. This post was initially intended to get some feedback on indoor GPS as a means to solving a much larger issue. I am designing an indoor system that needs to acquire local location form an object moving about in this 3d space. I have started to look into the Cricket Wireless Location System.
Thanks all.
