  2. Error analysis for the Global Positioning System - Wikipedia

    en.wikipedia.org/wiki/Error_analysis_for_the...

    When taken together, autonomous civilian GPS horizontal position fixes are typically accurate to about 15 meters (50 ft). These effects also reduce the more precise P(Y) code's accuracy. However, the advancement of technology means that in the present, civilian GPS fixes under a clear view of the sky are on average accurate to about 5 meters ...

  3. Global Positioning System - Wikipedia

    en.wikipedia.org/wiki/Global_Positioning_System

    As of early 2015, high-quality Standard Positioning Service (SPS) GPS receivers provided horizontal accuracy of better than 3.5 meters (11 ft), [10] although many factors such as receiver and antenna quality and atmospheric issues can affect this accuracy. GPS is owned and operated by the United States government as a national resource.

  4. GNSS enhancement - Wikipedia

    en.wikipedia.org/wiki/GNSS_enhancement

    The Global Positioning System (GPS) is the American satellite-based system for positioning and navigation. Receivers on or near the Earth's surface can determine their locations based on signals received from any four or more of the satellites in the network.

    At this confidence level, positional measurements are considered accurate enough to meet all but the most sensitive applications. 2–5 Good Represents a level that marks the minimum appropriate for making accurate decisions. Positional measurements could be used to make reliable in-route navigation suggestions to the user. 5–10 Moderate

    A speedometer or speed meter is a gauge that measures and displays the instantaneous speed of a vehicle. ... Instead, the GPS's positional accuracy, and therefore the ...

  7. Wide Area Augmentation System - Wikipedia

    en.wikipedia.org/wiki/Wide_Area_Augmentation_System

    GPS is simply not accurate enough to replace ILS systems. Typical accuracy is about 15 metres (49 ft), whereas even a "CAT I" approach, the least demanding, requires a vertical accuracy of 4 metres (13 ft). This inaccuracy in GPS is mostly due to large "billows" in the ionosphere, which slow the radio signal from the satellites by a random ...

  8. Time to first fix - Wikipedia

    en.wikipedia.org/wiki/Time_to_first_fix

    The TTFF is commonly broken down into three more specific scenarios, as defined in the GPS equipment guide: Cold or factory The receiver is missing or has inaccurate estimates of its position, velocity, the time, or the visibility of any of the GPS satellites. As such, the receiver must systematically search for all possible satellites.

  9. Receiver autonomous integrity monitoring - Wikipedia

    en.wikipedia.org/wiki/Receiver_Autonomous...

    The Global Positioning System (GPS) does not include any internal information about the integrity of its signals. It is possible for a GPS satellite to broadcast slightly incorrect information that will cause navigation information to be incorrect, but there is no way for the receiver to determine this using the standard techniques.
