IPhone : Indoor Atlas: iPhone sdk doesn't gives accurate position when we stop moving

I downloaded the Indoor Atlas iPhone SDK and also generate map paths and test paths for my venue. SDK navigates me perfectly when I am moving from one place to another but when I stop moving it generates scattered output with the position radius of 10 to 25. I am expecting precise co-ordinates in both the above cases in my project . Is there any way for precision?

Thanks.
