  2. Comparison of satellite navigation software - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_satellite...

    This is a list of notable commercial satellite navigation software (also known as GPS software) for various devices, with a specific focus on mobile phones, tablets, tablet PCs, (Android, iOS, Windows).

  3. Geodetic control network - Wikipedia

    en.wikipedia.org/wiki/Geodetic_control_network

    Electronic distance measurement (EDM) was introduced around 1960, when the prototype instruments became small enough to be used in the field. Instead of using only sparse and much less accurate distance measurements some control networks were established or updated by using trilateration more accurate distance measurements than was previously possible and no angle measurements.

  4. Pseudorange - Wikipedia

    en.wikipedia.org/wiki/Pseudorange

    The pseudorange (from pseudo-and range) is the pseudo distance between a satellite and a navigation satellite receiver (see GNSS positioning calculation), for instance Global Positioning System (GPS) receivers.

  5. Comparison of free off-line satellite navigation software

    en.wikipedia.org/wiki/Comparison_of_free_off...

    Very basic programs like this may not be suitable for road navigation in cars, but serve their purpose for navigation while walking or trekking, and for use at sea. To determine the GPS coordinates of a destination, one can use sites such as GPScoordinates.eu and GPS visualizer. Some software presented here is free, but maps may need to be paid ...

  6. GPS signals - Wikipedia

    en.wikipedia.org/wiki/GPS_signals

    GPS encodes this information into the navigation message and modulates it onto both the C/A and P(Y) ranging codes at 50 bit/s. The navigation message format described in this section is called LNAV data (for legacy navigation). The navigation message conveys information of three types: The GPS date and time, and the satellite's status.

  7. True-range multilateration - Wikipedia

    en.wikipedia.org/wiki/True-range_multilateration

    That name is selected because it: (a) is an accurate description and partially familiar terminology (multilateration is often used in this context); (b) avoids specifying the number of ranges involved (as does, e.g., range-range; (c) avoids implying an application (as do, e.g., DME/DME navigation or trilateration) and (d) and avoids confusion ...

  8. Real-time locating system - Wikipedia

    en.wikipedia.org/wiki/Real-time_locating_system

    ID signals from a tag are received by a multiplicity of readers in a sensory network, and a position is estimated using one or more locating algorithms, such as trilateration, multilateration, or triangulation. Equivalently, ID signals from several RTLS reference points can be received by a tag and relayed back to a location processor.

  9. Mobile phone tracking - Wikipedia

    en.wikipedia.org/wiki/Mobile_phone_tracking

    An indoor location tracking map on a mobile phone. Mobile phone tracking is a process for identifying the location of a mobile phone, whether stationary or moving. . Localization may be affected by a number of technologies, such as the multilateration of radio signals between (several) cell towers of the network and the phone or by simply
