🦄 Is Galileo Gps Fully Operational

After the fully operational global services of BDS-3 from July 31, 2020, this is the first time to assess the positioning performance of GPS/BDS-3/GLONASS/Galileo in polar regions. Galileo's Full Operational Capability (FOC) is expected for 2020, in a staggered approach from the IOC phase. Four new Galileo satellites were put on orbit on top of an Ariane 5, on July 25, 2018 from the European spaceport in Kourou, French Guiana. Besides existing operational global positioning systems i.e. GPS and GLONASS, another two have already emerged: GALILEO and Compass/Beidou. Alternatives to GPS imposed the GNSS concept, which has crystallized in a short time. The true reasoning of this excessive need for positioning information is beyond the scope of this paper; instead, an Abstract and Figures. Nowadays one can use four global navigation satellite systems (GNSS). Two of them are complete constellations (GPS, Glonass) and two (Beidou, Galileo) are already usable and The L1-SAIF signal at 1575.42 MHz is fully compatible with the GPS-SBAS and WAAS system while the L-EX signal at 1278.75 MHz provides a high-data rate signal (kbit/s) and is compatible with the E6 signal band of the European Galileo satellites - allowing QZSS to serve as an augmentation constellation for both GPS and Galileo. Galileo is the world's fourth geolocation satellite system, after ones created by the U.S., Russia and China, and has been pitched by the EU as a more accurate alternative to GPS. The EU has poured some €10 billion into the system, which has operated on a trial basis since late 2016 and is set to be fully operational by the mid-2020s with The most critical Galileo services will also remain available to EU Member States in crisis situations, which cannot be fully guaranteed for other satellite navigation systems. A significant part of Galileo services has been available since 2016. The intention is to declare the basic services fully operational in 2022. Abstract: Global Navigation Satellite System (GNSS) will in effect be fully deployed and operational in a few years, even with the delays in Galileo as a consequence of European Union's financial difficulties. The vastly broadened GNSS spectra, spread densely across 1146-1616 MHz, versus the narrow Global Positioning System (GPS) L1 and L2 bands, together with a constellation of over 100 GPS from the U.S. GLONASS from Russia. Galileo from European Union; BeiDou from China. Two regional systems: NavIC from India; QZSS from Japan. What is the need for NavIC when already others are Operating? GPS and GLONASS are operated by defence agencies of the respective nations. It is possible that the civilian service can be degraded or denied. aJoE.
