Japan launched a rocket carrying the local version of American GPS satellite with the Japanese GPS system to improve the stability of receiving radio waves and intensify the precision of positioning information used in smart phones and car navigation system.
Japan launched an H-2A rocket which carries the satellite called “Michibiki No.2” from a space centre in Tanegashima, southern Japan.
In 2010, the country launched the first Michibiki satellite on a trial basis into space and according to the cabinet office, it plans to send two more satellites later this year.
Once the four satellites are in orbit, one satellite at the minimum will be flying over Japan for eight hours per day.
The U.S. GPS has a margin of error of about 10 meters (about 33 feet) but on combining with the Japanese system positioning error will be diminished to only several centimeters (a few inches).
The system is expected to use for the activities such as driverless tractors in farming and to assist evolve automated construction machines.
By fiscal 2023 the government plans to have launched a total of seven satellites into orbit and secure Japan’s own GPS system without depending on the U.S. system.
