Technology:
A total of about
200 companies including Toyota,
Honda, and Mitsubishi Electric will establish an industry-government-academia research
organization coming July to promote industrial applications of the Japanese GSP.
The currently-used GPS analyzes the radio waves coming from U.S satellites to
figure out a position. The Japanese GPS uses 4-7 quasi zenith satellites going
around in the sky above the region from Japan
and Australia
describing a figure of eight. With the quasi-zenith satellite system, the error
will decrease from 10 m to less than 1 m, and ultimately to less than several
tens of centimeters. The organization plans to start substantiative experiment
toward 2016. The “Michibiki (guidance)” launched in September 2010 is currently
in operation. It stays just above Japan for eight hours a day. The
Japanese government has decided to launch three quasi satellites to set up a
four-satellite system by 2018.
With the technology
to be realized by the Japanese GPS, it will be possible to increase the guide
precision of the car navigation system and the accident prevention function of
a vehicle. Other applications include precise operation and control of
aircraft, even smoother train operation, detailed instructions on cropping
system, optimal pesticide spraying, automated operation of farm equipment, precise
control of construction machinery, and elaborate services for sightseers looking
for a sightseeing spot with a smartphone in hand. The Japanese GPS can be used
in the areas covered by the quasi zenith satellites including East Asia,
Southeast Asia, and Australia.
The Cabinet Office reckons that the position information service in the Asia
and Oceania regions will grow to about 11
trillion yen in 2020, accounting for 20% of the world market.
