    Lets have a review on the errors of GPS.
  •   Study   Slideshow
  • Caused by slight discrepancies in each satellite’s four atomic clocks.
    Satellite clock errors
  •  15
  • Variation in satellite orbits due to gravitational pull and solar pressure fluctuations.
    Orbit errors
  •  15
  • Causes the GPS satellite radio signals to be refracted as they pass through the earth’s atmosphere
    Ionospheric interference
  •  15
  • GPS errors are largely due to water vapor in this layer of the atmosphere. It is fairly insignificant to GPS.
    Tropospheric interference
  •  15
  • the electromagnetic field that the receiver’s internal electronics generate when it’s turned on.
    Receiver noise
  •  15
  • caused by reflected radio signals from surfaces near the GPS receiver
    Multipath interference
