Production Association Polyot (usually called ''Полёт'' by the aviation workers and pilots or ''ПО «Полёт»'' inside the company, while the official Russian name is: Производственное объединение «Полёт») (Polyot)〔Note: ''полёт (pa.lyót) ''is the Russian for'' flying, flight''〕 is a Russian aerospace engineering company best known for being the manufacturer of GLONASS satellites and the Kosmos-3M space launch vehicle. The company is based in Omsk, in the Russian Federation. In 2007, the company was integrated into the Khrunichev enterprise. Its full name is ''"Polyot" Manufacturing Corporation – A Branch of The Federal State Unitary Enterprise "Khrunichev State Research and Production Space Center".''〔(【引用サイトリンク】title=About the Enterprise )〕 ==Overview== The Kosmos-3M launch vehicle, produced at the company since 1969, has established a reputation as one of the most reliable rockets in its class with a reliability coefficient of 0.97.〔(【引用サイトリンク】title=Launch vehicle “Kosmos-3M” )〕 Polyot also develops navigation satellites, such as Nadezhda, Parus, GLONASS and GLONASS-M. In the aviation sector, the company's products include the AN-3T light multi-purpose aircraft, AN-70 transport aircraft and the AN-74 multi-purpose aircraft.〔(【引用サイトリンク】title=Aviation production )〕 PC Polyot is slated to produce the upcoming ''URM-1'' first stage of the Angara (rocket family), a part of Khrunichev's new Angara rocket family. The Angara is projected to become Russia's primary unmanned launch vehicle in the near future. The company will also take over the production of the Briz-KM upper stage, which is currently used on the Rockot launch vehicle, this module will function as the second stage of the Angara 1.2 launch vehicle. By 2015, 60 URM stages are expected to be produced at the company annually for Angara-3.2 and Angara 1.2 rockets.〔 The company has entered a partnership with the German company OHB-System, providing the Kosmos-3M launch vehicle〔 as well as designing and producing satellite platforms for OHB-System's ORBCOMM project. Six such satellites were launched on 19 June 2008 with the Cosmos-3M rocket:〔(【引用サイトリンク】title=Russia's Cosmos 3M rocket blasts off with six U.S. satellites )〕 one ORBCOMM CDS weighing 80 kg, and five ORBCOMM Quick Launches weighing 115 kg each.〔(OHB-System milestones )〕〔(OHB-System missions )〕 On November 9, 2009 ORBCOMM filed a report to the United States Securities and Exchange Commission stating that since launch, communications capability for three of the quick-launch satellites and the CDS has been lost.〔http://www.sec.gov/Archives/edgar/data/1361983/000095012309059834/c91352e10vq.htm〕 The failed satellites experienced attitude control system anomalies as well as anomalies with its power systems, which resulted in the satellites losing their proper orientation toward the sun and in reduced power generation. The company has filed a $50 million claim with its insurers covering the loss of all six satellites〔http://www.spacenews.com/satellite_telecom/091113-defective-satellites-hobble-orbcomms-ais-business.html〕 and received $44.5 million in compensation. In 2009, ORBCOMM turned to another satellite manufacturer to build 18 satellites for its second-generation constellation. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Production Corporation Polyot」の詳細全文を読む スポンサード リンク
