Kyoto Startup Drone Flies on Autopilot in Areas without GPS Reception
The
“seamless drone” created by developers in Kyoto Prefecture is seen entering a
warehouse that does not have GPS signal reception in the prefectural city of
Nantan, on July 20, 2020
A business venture in western Japan has developed
a drone that can be operated on autopilot in places with no GPS reception, such
as below girder bridges or in tunnels — a promising device for infrastructure
maintenance.
The “seamless drone” was created by Earth
Analyzer, a startup based in the city of Ayabe, Kyoto Prefecture. The drone
receives location information from sensors set up around places with no GPS
signals, which is converted into the same kind of signals used in GPS. This
enables the drone to automatically identify its location.
The first demonstration flight was unveiled on
July 20 at a warehouse of a construction company in the Kyoto prefectural city
of Nantan.
Once the command to takeoff was given to the drone
on standby outside the warehouse, the device floated in the air as its four
propellers made a humming noise. The drone flew to the entrance while following
a course along ribbons that were strung outside the warehouse, just as it had
been programmed to do, and hovered for a moment.
Then, a change was made to the system so that the source of location information transmitted to the drone was switched from GPS to a group of six sensors. The drone entered the warehouse, which was about the size of a small gym, and flew along a course indicated by the ribbons before leaving the warehouse. The drone hovered once more when going outside, and switched back to GPS signal. The drone indeed ran “seamlessly,” as its name suggests, and came to a stop right on a circular landing point marked with an “H.”

There had previously been no other option but for
people to operate drones manually inside buildings and other places where GPS
signals could not reach. Although there is also a method to operate drones by
equipping them with cameras and lasers and have them fly while analyzing
images, this method apparently requires slowing down their speed and there are
also limitations on the locations they can be flown.
The new drone system was developed in a joint
effort by Earth Analyzer, Tokushima University, and i System Research Corp., a
tech firm based in Kyoto’s Nakagyo Ward. The GPS used include those of the
United States, the Galileo systems of the EU, and Russia’s GLONASS. The
seamless drone also uses satellite signals apart from GPS, and the developers
are enhancing its precision.
The drone has already entered stages of practical
usage, and is apparently scheduled to fly through a water supply tunnel in
September after passing through a sluiceway in the Yura River in the city of
Fukuchiyama in northern Kyoto Prefecture.
Hisanori Araki, president of Earth Analyzer
emphasized the quality of the new system, saying,
“Japan’s
infrastructure has been showing signs of deterioration, and there is a high
potential demand for inspections by drones. Although manual operation requires
time for training skilled pilots, the seamless drone can be flown by anyone
even if you aren’t a skilled expert.”
