Why is it recommended to wait outside for at least 15 minutes after completing GPS positioning the first time?

• This wait allows the product to record future measurements and locations more accurately, even if GPS positioning is not enabled later on. Try to perform GPS positioning somewhere where you are not surrounded by tall buildings or other overhead obstructions that might interrupt GPS signals. Also keep the product still as you wait.

  You should also wait outside for 15 minutes if this is your first time performing GPS positioning after not using the product for several months.
