  2. Satellite navigation device - Wikipedia

    en.wikipedia.org/wiki/Satellite_navigation_device

    A satellite navigation device or satnav device, also known as a satellite navigation receiver or satnav receiver or simply a GPS device, is a user equipment that uses satellites of the Global Positioning System (GPS) or similar global navigation satellite systems (GNSS). A satnav device can determine the user's geographic coordinates and may ...

  3. GNSS applications - Wikipedia

    en.wikipedia.org/wiki/GNSS_applications

    Geo-fences can enable or disable devices based on their location. GNSS road pricing systems charge of road users using data from GNSS sensors inside vehicles. Advocates argue that road pricing using GNSS permits a number of policies such as tolling by distance on urban roads and can be used for many other applications in parking, insurance and ...

    The FCC has concerns U.S. handheld devices are receiving and processing Global Navigation Satellite System (GNSS) signals from satellites controlled by foreign adversaries in violation of ...

  6. GNSS software-defined receiver - Wikipedia

    en.wikipedia.org/wiki/GNSS_software-defined_receiver

    A software GNSS receiver is a Global Navigation Satellite System (GNSS) receiver that has been designed and implemented using software-defined radio.. A GNSS receiver, in general, is an electronic device that receives and digitally processes the signals from a navigation satellite constellation in order to provide position, velocity and time (of the receiver).

  7. Assisted GNSS - Wikipedia

    en.wikipedia.org/wiki/Assisted_GNSS

    Assisted GNSS (A-GNSS) is a GNSS augmentation system that often significantly improves the startup performance—i.e., time-to-first-fix (TTFF)—of a global navigation satellite system (GNSS). A-GNSS works by providing the necessary data to the device via a radio network instead of the slow satellite link, essentially "warming up" the receiver ...

  8. Galileo (satellite navigation) - Wikipedia

    en.wikipedia.org/wiki/Galileo_(satellite_navigation)

    All major GNSS receiver chips support Galileo and hundreds of end-user devices are compatible with Galileo. [10] The first, dual-frequency-GNSS-capable Android devices, which track more than one radio signal from each satellite, E1 and E5a frequencies for Galileo, were the Huawei Mate 20 line, Xiaomi Mi 8, Xiaomi Mi 9 and Xiaomi Mi MIX 3.
