The government started the discussion that encrypted a part of the radio signal of the positioning about semi-zenith satellite "MICHIBIKI" that aimed at the accuracy improvement of the positioning on the 12th.
It clarified it by the state affairs officer class meeting of eight prefecture ministries that talked about the development plan.
It is discussed to provide the commercial utilization with the encrypted hertzian wave in charge besides making it to the government agency exclusive uses such as the Self Defense Forces and the police, and will bring a concrete idea together by March, '11.

The first machine was launched in September so that the MICHIBIKI might supplement global positioning system (GPS) of the rice used for the car navigation system etc.
However, the general plan including the development since the second is undecided.

In the encryption, it is a purpose to prevent the obstruction such as "Disguise" that mix wrong information.
The positioning satellite in Europe refers to the charging of the code hertzian wave besides there is a military hertzian wave of the high accuracy that the civilian cannot use even for GPS and it refers to these by the under discussion.

The possibility that the high accuracy of the article for sale is limited to a part of use has come out though the MICHIBIKI was planned by the assumption that everyone can use free of charge.

Moreover, review, "Four or more is necessary for 24 hour management", and the clarification of the policy conventionally at the time of came as "Minimum three is necessary for the MICHIBIKI" in the meeting on the same day.
Six MICHIBIKIs and three synchronous satellites ..combination.. were assumed to discuss the construction of "Japanese version GPS" by the the greatest.
It increases the number, the reception region is expanded, and there is an idea used for Official Development Assistance (ODA) to Southeast Asia and the Pacific Ocean nations, too.
