GLONASS, alongside GPS, Galileo, Beidou and others are working towards the goal of providing the most accurate data for its users. Each navigation system has its differences and main area it focuses on the most. GLONASS is a Russian satellite-based navigation system that works as an alternative to GPS. GLONASS and GPS can together provide 20%
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.
Assessing the contribution of Galileo to GPS+GLONASS PPP: Towards full operational capability. Sermet Ogutcu. Add to Mendeley. Get rights and content. •. Galileo contribution to GPS+GLONASS PPP was investigated. •. Outliers were significantly reduced when adding Galileo to GPS+GLONASS PPP. •.
Galileo (EU) Developed by the European Union in 2011, Galileo will consist of 30 satellites when it is fully operational (i.e., 24 working satellites with six spares). It provides a more accurate positioning service at higher latitudes than other GNSS systems by using over 24 satellites in six orbital planes.

The fully deployed Galileo system will consist of 30 operational satellites and 6 in-orbit spares. As of now 22 out of 30 satell ites are in orbit.
The performances requirements for each service are the following: Galileo Open Service Performances. The expected performance once full deployment of the Galileo system at FOC are [1] : Galileo declared its Initial Services status in December 2016 as the first step towards full operational capability.
GPs 3 SV06 is expected to enter operational service a few months after launch. In its launch configuration fully fueled with propellant, the GPS 3 SV06 satellite weighed 9,595 pounds (4,352
With more precise satellite clocks, faster satellite orbit determination and improved signal modulation and larger bandwidth, the Galileo system promises a better performance when it is fully operational, compared to existing fully operational GNSS (i.e., GPS and GLONASS), in particular in terms of the effect of multipath interference.
The Global Positioning System (GPS) was the first global navigation satellite system (GNSS), but has been followed by the three other systems listed in the table (note that BeiDou and Galileo are not fully operational as of 2016). In addition to being globally available systems for positioning and navigation, GNSS systems are widely used as
When Galileo, Europe's own global satellite navigation system, is fully operational, there will be 30 new satellites in Medium Earth Orbit (MEO) around the Earth at an altitude of 23 616 km. Ten satellites will occupy each of three orbital planes inclined at an angle of 56° to the equator (see diagram). The satellites will be spread around each plane and will take about 14 hours to orbit
