This is a list of past and present satellites of the Galileo navigation system . As of August 2023, 28 Galileo (4 IOV "In Orbit Validation" and 24 FOC "Full Operational Capability") satellites have been launched. The 2 GIOVE prototype vehicles were retired in 2012, 23 satellites are operational, 1 is not available and 4 are currently not usable.
Operational satellites The complete Galileo constellation will comprise satellites spread evenly around three orbital planes inclined at an angle of 56 degrees to the equator. Each satellite will take about 14 hours to orbit the Earth. One satellite in each plane will be a spare, on stand-by should any operational satellite fail. From most locations, six to eight satellites will always be
As for the quality of the OSB products, the data availability (DA) of the GPS and Galileo satellites was greater than 97%, whereas that of BDS was less than 60%; the maximum fluctuation value (MAX) and standard deviation (STD) of the GPS, Galileo, and BDS satellites were 0.045 and 0.012; 0.081 and 0.028; and 0.292 and 0.085 cycles, respectively.
Galileo is Europe's GNSS solution (i.e Europe's version of GPS). As of December 2016, 18 of the 30 planned satellites are in orbit. Galileo has started offering Early Operational Capability and is expected to be fully operational in 2019. The Galileo GNSS solution operates in the following frequency bands:
SDCM and other SBAS systems under development to become operational. When these evolutions are completed it is thought that the global SBAS coverage will suffer an increase from the 7.54% at 99% (only WAAS, EGNOS and MSAS) to 92.65%, considering the use of multiple-constellation (GPS and Galileo).
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.
Galileo is a global navigation satellite system (GNSS) that went live in 2016, created by the European Union through the European Space Agency (ESA), operated by the European Union Agency for the Space Programme (EUSPA), headquartered in Prague, Czechia, with two ground operations centres in Fucino, Italy, and Oberpfaffenhofen, Germany.
Galileo is fully interoperable with GPS, and their combined use will bring many benefits to the end user. Galileo satellites will offer more usable satellites, meaning more accurate and reliable positioning and timing synchronization for end users.
A fully operational constellation with global coverage consists of 24 satellites, while 18 satellites are necessary for covering the territory of Russia. which will use modulation similar to modernized GPS, Galileo, and BeiDou. Glonass-K consist of 26 satellites having satellite index 65-98 and widely used in Russian Military space.
Galileo: en route to full operational capability. Date : Fri, Nov 26, 2021 | 07:30 - 09:00 GMT | 08:30 - 10:00 CET. Replay : Fri, Nov 26, 2021 | 16:00 - 17:30 GMT | 17:00 - 18:30 CET. Type: ESA TV Exchange. Soon another pair of Galileo satellites will be launched on top of a Soyuz from Europe spaceport in French Guyana.
