QZSS and the Growing Role of GNSS in Asia

The presentation was titled ‘Concept of Multi-GNSS Demonstration Campaign in Asia Oceania region and Application to the Transportation Area and can be downloaded or viewed online.

This new satellite will provide advanced coverage for the Asian area, and it is expected to augment already available satellites used for GNSS pruposes. The idea behind QZSS is to enable full GNSS availability throughout the region, thus increasing application security through available numbers. Due to it’s orientation, this will also extend into the inner cities, making these services available where it is often difficult to provide good signal strengths. Consequently, mobility applications are expected to flourish.

With multiple satellites in space forming larger GNSS networks, the constellation is expected to grow from around 60 available satellites now to over 100 within 10 years.

With precise point positioning (PPP) applications such as collision guidance between cars becoming more of a reality (and possibility). Such applications in turn will depend upon higher quality digital elevation models that support the notion of 3D road spaces and movements in all directions.

A new Multi-GNSS Era is about to unfold with QZSS becoming a primary participant in the Asian region.
