Which of the following is the most significant source of error in position from GPS signals?
A. Atmospheric effects
The GPS signals have to travel through charged particles and water vapors in the atmosphere which delays its transmission. Since the atmosphere varies at different places and at different times, it is not possible to accurately compensate for the delays that occur.
