It connected between the Ogasawaramura clinic and Tokyo metropolitan Hiro-o Hospital by satellite "KIZUNA" as a demonstration of the telemedicine in the region without the high-speed communication circuit, the communication experiment was done, and the result was announced.

Japan Aerospace Exploration Agency (hereafter, JAXA) and Tokyo Ogasawaramura (hereafter, Ogasawaramura) announced the consequence of the demonstration of the telemedicine that connected the Ogasawaramura clinic and Tokyo metropolitan Hiro-o Hospital (hereafter, Hiro-o Hospital) by using Internet satellite "KIZUNA" on December 1 and had done on November 30.

When the effectiveness of the satellite communication was able to be demonstrated by the telemedicine intended for "Digital divide (digital divide)" region without the high-speed communication circuit by this experiment, it is Iu according to JAXA.

Various data of 24Mbps and 3 channels was able to be transmitted by using the satellite communication of KIZUNA though the existing circuit between the Ogasawaramura clinic and Hiro-o Hospital was 64kbps. About 3Mbps and hi-vision TV conference are about 9Mbps.  about 12Mbps, the endoscope image, and echo the hi-vision image in the radiograph etc. the break-down

This experiment was executed with a mock patient and a simulator concerning the following experimental selections.

It confers the case for the emergency in the early plural multiple injury patient accruals.
Double check of diagnostic support blood typing by upper gastrointestinal tract endoscope moving image transmission
Technical assistance of treatment(burr hole opening haematoma drainage and pleural cavity drain insertion)

It is assumed, "It is possible to do safely before treatment with high urgency is transported by doing stable high-speed communication, and lead to the amelioration of the condition of the patient" in JAXA.
It is enabled the demonstration of "There are effects also in can ..treatment.. conclusion in situ, and decreasing the flying boat transportation" and others and "It is useful also for the improvement of the accuracy of the diagnosis and treatment by looking over plural doctors".

The JAXA press release: The performance result of the telemedicine demonstration in the digital divide region by ultrahigh-speed Internet satellite "KIZUNA" (WINDS) is one in December, 2010 Http://www.jaxa.jp/press/2010/12/20101201_kizuna_j.html.

Japan Aerospace Exploration Agency announced that they sent the positioning signal from semi-zenith satellite "MICHIBIKI" that corroborated Global Positioning System (GPS) used for the car navigation system etc. on the 15th and aimed at the accuracy improvement, and started the demonstration test for high accurateness and use.
It uses it to research automated system operation of agricultural tractor etc. using the position information of high accuracy.

If the accuracy of the signal can be improved up to one meter in the error margin spending 3-6 months, and the accuracy of the target be put out, the transmission is scheduled to be started for the general user according to the spacecraft structure.
When the development of the provision by which seven enterprise companies of the inside and outside the country receive the signal of the satellite is planned, and cooperation is requested to the spacecraft structure, it is Iu now.

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.

To construct Japanese version GPS (global positioning system) on the fourth, the government decided the policy of intensively launching the homotype machine of semi-zenith satellite "MICHIBIKI" and the synchronous satellite by 6-7 planes in about two years from 2014.

The system that the positioning can be done by accuracy that is ten times higher than present GPS is straightened for the whole area of the Asia Pacific Ocean.
The private capital is scheduled to be used for the charge of 200 billion yen in total dimension that hangs to the launch etc.

The space development strategy headquarters of the government (general manager and sedge Prime Minister) is hardening the original bill, and the plan is decided on in around August.
The inside and the government of financial difficulty plan to fil the amendment bill of the PFI law that uses the private capital and know-how to the next regular session of the Diet, and to add the satellite manufacturing to the object business of PFI.

Japanese original GPS is constructed because even sending the hertzian wave for the private organization is obstructed to the third country, and the civil life and the economic activity might be influenced in the emergency etc. for the military use from an original purpose of GPS of the United States.

Japan launched the first machine "MICHIBIKI" of the semi-zenith satellite originally developed in September, '10.
The homotype machine also makes to three inclusion or more, and one plane will always be located in the sky over Japan.
If you combine with GPS that the United States operates
The accuracy such as the car navigations rises by ten times now, and the error margin becomes small up to one meter.

It is front loaded Shite as for the reentry plan to Venus to which Japan Aerospace Exploration Agency (JAXA) came as "Six years later" for one year, and discussing the rechallenge after five years has understood the fourth of failing probe "Morning twilight" the infusion of Venus to the rotating orbit.
The power output in the strategy that waits to overtake due to the trouble surfaces, and the dropping engine is assumed ..feasible.. plan and has surfaced the slow ..morning twilight.. slowdown, and surfacing of Venus, and.
It is expected that the period cutback will work advantageously in respect of the longevity of the equipment. 【 Daisuke Yamada ]

The morning twilight reversely jetted the engine to the closest approach lingua side in Venus on December 7 last year, slowed down rapidly, fetched about in the gravitation of Venus, and surroundings scheduled it being made turn.
However, the suspension in about two and a half minutes when engines are shorter than plans.
The speed doesn't fall enough, pass Venus, fly the sun now, and the rotating orbits fly faster than Venus.

Venus does JAXA at first and the morning twilight does the sun 11 times ten times while it does.
It was scheduled that it was made to approach most in December, '16 after six years when Venus became "Delay at the orbiting" - January, '17.
However, it turns out that the power output of the engine has fallen into about 60 percent for the investigation afterwards.
Obstacle of fueling by malfunction of valve of piping
There is a possibility of the breakage of the engine nozzle, and complete restoration is a tough going.

If the jet is weak, reentry to need the sudden deceleration at the closest approach becomes difficult.
The speed of the morning twilight was made to slow down little by little, and therefore, JAXA started sunning and started the discussion to make after five years doing overtake Venus eight times.
If time acts rashly, the hazard of the equipment failure by the radiation from the sun is reduced, and the long term monitoring after the infusion of Venus also wears reality.

The JAXA affiliate「Perhaps, it cannot be reentered at first at the speed of the plan. It wants to discuss all the possibilities, and to achieve the observation of Venus. 」It speaks.
