Vietnam developed the North Dau navigation system receiver

Hanoi University of Science and Technology successfully developed the receiver operating with China's North Pole Navigation System.

Bac Dau is compatible with the US GPS navigation system, European Galileo system and Glonass of Russia. Bac Dau provides free civil navigation services with a range of 10m accuracy, and military service with accuracy up to 10cm. The birth of Bac Dau positioning system provides more options for location services for users worldwide.

With the aim of self-researching, developing and mastering the technology of manufacturing transceiver systems operating with multi-global satellite systems (multi-GNSS), the research group of the International Center for Development Research Satellite positioning technology (NAVIS), Hanoi University of Technology has developed the North Dau receiver as soon as the system starts to provide services in December 2012.

The North American receiver developed by NAVIS is operating stably. Truong Minh Duc, head of NAVIS design team, said: 'Apart from China, the world has not yet disseminated North Dau trade receivers. Therefore, the successful development of Bac Dau collection is an important achievement in the field of satellite navigation in Vietnam ".

The testing process of Bac Dau collection shows that, for users in the Asia-Pacific region, including Vietnam, the North Dau navigation system is capable of providing location services with availability. High screen, reduce the complexity of positioning calculations in the receiver. These strengths are due to the addition of the medium-range Earth Orbital (MEO) as other satellite navigation systems, Bac Dau also uses geostationary orbits (GEO), and Earth synchronous orbits. inclined (IGSO) helps increase the ability of the receiver to 'see' satellites.

Bac Dau collection also added an important component in NAVISOFT collection system which is being developed by NAVIS Center. NAVISOFT is capable of operating with all global positioning satellite systems (GPS, GLONASS, Galileo and Bac Dau), as well as being able to receive information rectified by Japan's QZSS positioning satellite system Version provided.

In particular, in addition to operating each individual system (stand-alone), NAVISOFT also integrates the ability to simultaneously coordinate positioning signals coming from these systems in mixed positioning solutions. This is an advanced and advanced feature that enhances the accuracy, availability, continuity and reliability of the positioning solution.
