Sources of GPS Error Signal slows as it passes through the atmosphere Signal multipath occurs when the GPS signal is reflected off objects such as tall buildings or large rock surfaces before it reaches the receiver. Number of satellites visible-buildings, terrain, electronic interference, or sometimes even dense foliage can block signal reception Receiver clock errors- receiver's built-in clock is not as accurate as the atomic clocks onboard the GPS satellites.
