I'm currently coding a gps location application, and I have found out, that there is huge difference between hardware and units.
Having tried on the Wildfire S, Galaxy S2, GalaxyTab 10,1, and others, I find that the GPS position update frequency seems to vary from about half a second to half a minute (after getting the initial fix, and having free sight up). The Wildfire S performing worst, and the tablet performing best.
Does there exist a table somewhere that compares the GPS hardware/chipset and CPU, with possible times?
I would be grateful to hear about your experiences.
