Advantages of QZSS

In recent years more countries are developing and establishing original satellite positioning systems. However, QZSS is superior to these systems. As many countries launch positioning satellites, only Japan's QZSS is highly compatible with GPS and can be used with GPS in an integrated way; QZSS and GPS can be utilized as a single group of satellites. To put it simply, with QZSS it is like the number of GPS satellites has been increased. Because QZSS can be used in an integrated way with GPS, the number of satellites that can transmit satellite signals at the same time is increased, which makes highly precise, stable positioning possible. This also decreases the positioning errors as described.
