  2. Global Positioning System - Wikipedia

    en.wikipedia.org/wiki/Global_Positioning_System

    GPS data mining: It is possible to aggregate GPS data from multiple users to understand movement patterns, common trajectories and interesting locations. [123] GPS data is today used in transportation and disaster engineering to forecast mobility in normal and evacuation situations (e.g., hurricanes, wildfires, earthquakes). [124] [125] [126] [127]

    The ionospheric data are transmitted via satellite in Satellite Based Augmentation Systems (SBAS) such as Wide Area Augmentation System (WAAS) (available in North America and Hawaii), EGNOS (Europe and Asia), Multi-functional Satellite Augmentation System (MSAS) (Japan), and GPS Aided Geo Augmented Navigation (GAGAN) (India) which transmits it ...

  4. General Problem Solver - Wikipedia

    en.wikipedia.org/wiki/General_Problem_Solver

    General Problem Solver (GPS) is a computer program created in 1957 by Herbert A. Simon, J. C. Shaw, and Allen Newell (RAND Corporation) intended to work as a universal problem solver machine. In contrast to the former Logic Theorist project, the GPS works with means–ends analysis .

  5. GPS/INS - Wikipedia

    en.wikipedia.org/wiki/GPS/INS

    GPS/INS is commonly used on aircraft for navigation purposes. Using GPS/INS allows for smoother position and velocity estimates that can be provided at a sampling rate faster than the GPS receiver. This also allows for accurate estimation of the aircraft attitude (roll, pitch, and yaw) [citation needed] angles.

  6. Map matching - Wikipedia

    en.wikipedia.org/wiki/Map_matching

    Topological map matching aligns GPS points with a road network by considering the connectivity and relationships between road segments. It accounts for the structure of the network, path constraints, and the sequence of GPS points to provide accurate and realistic route matching, especially in complex environments.

  7. Positioning system - Wikipedia

    en.wikipedia.org/wiki/Positioning_system

    A major subclass is made of geopositioning systems, used for determining an object's position with respect to Earth, i.e., its geographical position; one of the most well-known and commonly used geopositioning systems is the Global Positioning System (GPS) and similar global navigation satellite systems (GNSS).

  8. 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.

  9. GPS tracking unit - Wikipedia

    en.wikipedia.org/wiki/GPS_tracking_unit

    A data pusher is the most common type of GPS tracking unit, used for asset tracking, personal tracking and vehicle tracking systems. Virtually every cell phone is in this mode per user agreement, even if shut off or disabled storing the data for future transmission.
