Then use the great-circle distance formula. THough in reality, when looking at such short distances with respect to the planet's radius, a simple 2D euclidean distance between two points is going to be close enough.

I will take the question literally, without trying to guess what you really meant:

  1. you have to get a second position (where you are)
  2. calculate the distance between the 2 locations
  3. check if it is less than 10 meters

Once you get the current position you could calculate the distance between those two points and test if it is less than 10 meters.
