I'm looking around for a decent GPS module for a project of mine. The Sparkfun GPS Buying Guide is nice, but focuses mostly on modules with patch antennae.
My project is a wrist- or upper-arm-mounted GPS logger. It will be displayless and log continually, and thus there can be no assumptions about the orientation of the device (as there probably could be if the user were to read a display). As far as I've understood, this means I should go for a helical antenna instead of a patch one for better omnidirectionality. Is this correct?
If so, does anyone have any recommendations for a decent (and decently priced) GPS module with a helical antenna? An antenna-less module with a third-party antenna is also possible, but I'd prefer a complete module. The last time I looked into this a few months ago, the most interesting device I found was the Falcom FSA03 based on the u-blox UBX-G5010. I also see there's a UBX-G6010 based FSA03-LP out now. Does anybody have any experience with these?
Edit: I've also been hearing about PCB loop antennae. Any experiences with those? From what I've understood, these are often used in cellphones...
I don't have very specific requirements, but the size should be small. I'm not looking for the tiniest of the tiny, but it shouldn't be bulky either - this is vague, I know, but I'm looking for something suited to a small wrist-mounted device. Low power consumption is important. And of course, the more reasonably priced, the better.
Thanks in advance for any recommendations!
Conclusion (in case anybody comes across this at a later point): I went for a u-blox LEA-6H module ($50 on eBay) and a Sarantel SL1300 antenna (€10 at Mirifica). I haven't had the time to try things out yet, but it seems to be exactly what I need.
