Successfully decode the signal Galileo global positioning satellite system

International Center for Research and Development of Satellite Positioning Technology (NAVIS), Hanoi University of Technology has just received and successfully decoded the positioning signals of the first satellites of the Guard System. Galileo global positioning system of the European Union.

Galileo global positioning satellite system is expected to be completed by 2020, with 27 orbit satellites.

So far, Galileo has four satellites operating in orbit, with two satellites launched in mid-October.

These satellites cater to the system's In-Orbit Validation phase.

According to the basic principle of positioning using satellites, to use location services provided by the Galileo system requires the receiver to receive signals of at least four Galileo satellites at the same time.

On December 17, 2012, for the first time all four Galileo satellites appeared and distributed the free galvanizing E1OS signal in the sky of Hanoi.

At that time, the research team at NAVIS Center tested the use of Galileo location services.

The results showed that the Navisoft receiver developed by the Center was successful in receiving and fully decoding four Galileo satellites, PFM, FM2, FM3 and FM4 with distance codes corresponding to 11, 12, 19 and 20.

Dr. La The Vinh, who directly participates in the process of decoding Galileo signals, said that the successful reception and decoding of Galileo signals has an important meaning in the willingness to master and develop solutions. Multi-system positioning, which enhances the accuracy, reliability of location services and particularly reduces dependence on a single navigation system.
