The United Kingdom Global Navigation Satellite System (UK GNSS) was a United Kingdom Space Agency (UKSA) research programme which, between May 2018 and September 2020, developed outline proposals for a United Kingdom (UK) owned and operated conventional satellite navigation system, as a British alternative to the European Union (EU) owned and operated Galileo Global Navigation Satellite System.
Satellite navigation is a system that uses satellites to provide geolocation and time information to a receiver on Earth. GNSS is a term that refers to the global navigation satellite systems that operate worldwide, such as GPS, GLONASS, Galileo and BeiDou.

Samples of three GPS satellites' orbits over a five-year period (2013 to 2018) USA-242 · USA-239 · USA-151 · Earth As of 15 August 2023, 83 Global Positioning System navigation satellites have been built: 31 are launched and operational, 4 are unhealthy or in reserve, 41 are retired, 2 were lost during launch, and 1 prototype was never launched. 4 Block III satellites have completed ...
The Global Positioning System ( GPS ), originally Navstar GPS, [2] is a satellite-based radio navigation system owned by the United States government and operated by the United States Space Force. [3] It is one of the global navigation satellite systems (GNSS) that provide geolocation and time information to a GPS receiver anywhere on or near ...
All major GNSS receiver chips support Galileo and hundreds of end-user devices are compatible with Galileo. 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.
National GPS Network. The British National GPS Network, known as OS Net, is a network of global navigation satellite system GNSS base stations covering Great Britain. [1] It is managed by Ordnance Survey . It provides access to a stable, national coordinate reference system (through downloaded GNSS data) that allows highly accurate location to ...
Geometry of GNSS-IR. GNSS Interferometric Reflectometry (or GNSS-IR) is a specialized case of GNSS-R. Here the receiving instrument is on the surface of the Earth. In this technique the interference of the direct and reflected signals is used rather than a Delay Dopper Map or measuring the two signals separately.
The quad-GNSS SiRFstarV™ 5ea delivers a number of exciting features to the automotive market, including simultaneous tracking of GPS and other supported constellations, LTE immunity and MEMS ...
