Glonass: l'état actuel

"In July or August will launch a GLONASS-M, September-October will be another three starts (satellite navigation) from Baikonur," - he said. AE Shilov said that before launching should conduct all necessary tests and to observe safety precautions.

Deputy Head of Russian Federal Space Agency said that so far the GLONASS system equipped with 23% of the aircraft of the Russian Federation, 87% of marine and river vessels, 80% of vehicles (we are talking about public transport).

La constellation de satellites russes de navigation GLONASS couvre l'intégralité du territoire russe et 98% de la planète, a annoncé mardi le directeur de l'Agence fédérale spatiale russe (Roskosmos) Anatoli Perminov au micro de la Voix de Russie.

"Actuellement, 27 satellites se trouvent en orbite, dont 22 sont en service et quatre sont en cours de test. Récemment, un satellite de nouvelle génération Glonass-K a été mis en orbite, il également testé. La constellation existante permet de couvrir 100% du territoire de notre pays et 98% de celui de notre planète", a indiqué le directeur de Roskosmos.

"Au deuxième semestre de cette année, nous entendons lancer quatre satellites Glonass-M, et un nouveau satellite Glonass-K en fin de l'année. Pourquoi en fin d'année? Parce qu'il faut procéder aux essais de vol du satellite existant, constater les défauts et les corriger sur le prochain satellite, avant de le mettre en orbite", a expliqué le responsable.

Le système de navigation GLONASS est l'équivalent russe du GPS américain, permettant de déterminer les coordonnées d'un objet sur terre et en mer au mètre près.

MOSCOU, 1er Juin (Xinhua) -- L'Agence spatiale russe Roskosmos envisage de lancer cinq satellites Glonass-M et un satellite Glonass-K en 2011, a annoncé mercredi le chef adjoint de Roscosmos, Anatoli Shilov.

Le premier lancement du satellite Glonass-M est prévu pour le mois d'août et le second devrait intervenir en octobre, a assuré M. Shilov lors d'un forum de navigation à Moscou.

La nouvelle génération de satellite Glonass-K devrait être lancée en décembre, a-t-il ajouté.

"D'ailleurs, nous espérons toujours procéder à un lancement groupé de trois satellites Glonass-M à bord d'une fusée Proton-M depuis le cosmodrome de Baïkonour à la fin de l'année", a-t-il déclaré cité par l'agence de presse Interfax.

La date du lancement groupé n'a pas encore été déterminée, a- t-il ajouté.

En décembre dernier, une fusée Proton-M, qui a décollé du cosmodrome de Baïkonour au Kazakhstan, a omis de remettre trois satellites de navigation Glonass-M sur orbite. Les satellites sont tombés dans l'océan Pacifique. Les enquêteurs ont accusé plus tard l'équipage au sol d'avoir pompé trop de carburant dans une fusée d'appoint.

2 satellites provisoirement en maintenance

In addition, Mr Popovkin said that in Roskosmos completes formation of new federal program "GLONASS", for the period until 2020.
"Right now, the forming of the Federal Program" GLONASS ". We ask for this program 402 billion rubles to 2020 ", - said Vladimir Popovkin.
According to him, these funds will be allocated to support the constellation of GLONASS, the development and maintenance of navigational charts with the specified requirements, as well as the development of various supplements to the consumer navigation equipment that will make GLONASS system more attractive . The latter problem will be solved by the scheme of double financing, involving the resources of the regions.
V. Popovkin said that currently the financial parameters of the future of the program discussed with the Ministry of Finance and Economic Development.

In 2011, from Baikonur can be made ​​one run rocket "Proton-M" with three spacecraft global positioning system GLONASS. However, it will be used by the upper stage "Briz-M" instead of DM-03, told the Russian Space Agency head Vladimir Popovkin.
Replacing the booster due to the fact that in December last year when running launcher "Proton-M" for a reason refill Stage DM -03 lost three GLONASS satellites.
"This year is the ability to run three satellites of the GLONASS system," Proton "from Baikonur - said Popovkin. - Signed a decision that this start will be used by the upper stage" Briz-M ". It is now being approved by the Ministry of Defense. "
As for the upper stage DM-03, then, according to Popovkin, go with it "routine activities", for which it will take some time.

Federal Space Agency agrees to early August the Federal Program funding "GLONASS"
:: 07/28/2011

All questions on the financing of the federal target program "GLONASS", designed before 2020, will be resolved in the next few days, told the Russian Space Agency head Vladimir Popovkin.

"Almost all issues have been resolved. In July, the maximum in early August, the program will complete the form," - said Popovkin.

He noted that he was satisfied with the way the financial aspects of program coordination. Earlier the head of Russian Space Agency informed reporters that the agency asked the federal program "GLONASS" 402 billion rubles by 2020.

Popovkin said that at present under orders Prime Minister concludes agreement on financing the program with relevant agencies, including the Ministry of Finance, Economic Development and Ministry of Industry.

"To date, all issues related to the allocation of finance needed for the organization itself constellation have been resolved. But we do not yet specify how much money is necessary for the effective use of the GLONASS system, which some of them must come from the federal budget, and which - from business, "- said the head of Russian Federal Space Agency.

According to him, we are talking about the tools needed to develop and update the navigation map with the specified parameters, the development of various additions to the navigation equipment that will make GLONASS system more attractive to consumers.

Posted on pension GPS satellite has returned to work. In the constellation of spacecraft was introduced in 1993. He was supposed to work in space seven years, but it blamed on old age, only two years ago. Now the device is re-injected into the group, it will replace the failed over a new satellite in 1996, according to Russian news service.
