I am reading location from GPS module. But every time, i am getting different location. I are getting information about
1. latitude and longitude
2. Time
3. Horizontal Estimated Positional Error
4. Heading
5. vertical speed
6. horizonatl speed
7. Altitude
8. Location uncertainty angle
9. Standard deviation of axis along
10. Standard deviation of axis perpendicular to

Based on above information. How can i fix to nearest location with minimum error? Is there any method or logic to get nearby location?

Best Regards
Learner

What is the magnitude of the positional errors are you getting and what magnitude of positional error are you wanting. Most GPS devices should give a position to within 10 meters given an open sky and a low DOP (I suspect this is item 3 in your list).

I don't understand your second question.
A bit of light reading for you if it helps is here
