            Small GEO mission - signature at ILA 2008


            27 May 2008
            Today - during the Berlin Air Show, ILA 2008 - ESA and Hispasat S.A.
            (Spain) signed a preliminary authorisation to proceed for the Small
            GEO Mission. This will launch the initial activities of an
            industrial consortium led by Hispasat.
             
            The signing took place in the presence of representatives from the
            German Space Agency (DLR), the Spanish Delegation to ESA (CDTI) and
            OHB-System AG.
             
            The Small GEO Programme is aimed at the development of a small,
            general-purpose geostationary satellite platform, which will enable
            European industry to compete effectively in the commercial telecom
            market for small platforms.  
             
            ARTES 11
             
            To achieve this objective, ESA has established an element in its
            ARTES (Advanced Research in Telecommunications Systems) Programme.
            This element, known as ARTES 11, is divided into two parts.
             
            The first part covers the development of a platform supporting a
            payload mass of up to 300 kg, a payload power demand of up to 3 kW,
            and an operational lifetime of up to 15 years.
             
            The second part, the subject of the preliminary authorization to
            proceed that has just been signed, involves the development and
            launch of a Small GEO satellite and associated mission to provide
            flight qualification and in-orbit demonstration for the platform.
             
             
            A consortium led by the German company OHB-System AG is developing
            the Small Geostationary Platform. Work started in March 2007. The
            core team of companies that is jointly developing and will later
            commercialise the platform includes, besides OHB-System AG and its
            Luxembourg subsidiary LuxSpace, the Swedish Space Corporation, Carlo
            Gavazzi Space (Italy), and Oerlikon (Switzerland).
             
            The platform development is proceeding according to plan. The
            definition phase has been completed and the detailed design,
            manufacturing and testing of the platform is about to start. To this
            end, the selection of the equipment suppliers for the main platform
            elements has been completed.
             
            The selection of Hispasat for the Small GEO mission was made through
            an open Call for Interest issued by ESA in June 2007. Following the
            selection, a Request For Quotation was issued by ESA to Hispasat in
            August 2007. The mission proposal was positively evaluated by end of
            2007.
             
             
            Hispasat AG1
             
            The resulting satellite, Hispasat AG1, will serve as an important
            and distinctive asset in Hispasat's satellite fleet with:
              a communication capacity of up to 24 transponders in Ku-band and
              three transponders in Ka-band
              a highly innovative payload, REDSAT, led by Spanish industry. The
              REDSAT payload includes an active Direct Radiating Array (DRA)
              antenna providing four reconfigurable uplink beams in Ku-band and
              an advanced on-board processor providing four regenerative
              channels of 36 MHz
            Hispasat, a leading operator for the Spanish and Portuguese speaking
            markets, will be in position to push European innovative
            technologies to the telecommunication satellite commercial arena
            leading to the exploitation of enhanced services.
             
            To develop the mission, Hispasat has built the necessary industrial
            team to implement all the programme elements. OHB-System AG will act
            as the Satellite Prime Contractor. TESAT GmbH (Germany) will be the
            Payload Prime and will be responsible for the integration of the
            Transparent Repeater (produced by TESAT) and the REDSAT payload.
             
            The development of the REDSAT payload will be led by Thales Alenia
            Space-Espa

Buyers Bemoan Launcher Prices, Availability

                              Buyers Bemoan Launcher Prices, Availability

                              By Peter B. de Selding, PARIS
                              Space News Correspondent


                              Launch-services suppliers found themselves on the
                              defensive the week of Sept. 8 as satellite-fleet
                              operators and satellite manufacturers said rocket
                              reliability and supply was the Achilles heel of
                              the otherwise robust commercial telecommunications
                              satellite market.

                              Repeatedly during the World Satellite Business
                              Week here Sept. 8-11 organized by Euroconsult,
                              satellite operators said
!!! the availability of rockets is the principal risk to their growth
                              prospects.
                              One operator went so far as to suggest that rocket
                              builders build an inventory of vehicles that would
                              be ready for launch in the event of a failure — a
                              proposal that a commercial launch-services company
                              official said is "beyond belief. Has he looked at
                              our operating margins recently? Who is supposed to
                              finance that inventory?"
                           
  Satellite manufacturers joined the debate, and
                              most of them pointed to rocket builders as the
                              biggest problem currently facing the industry.
                       
      "The biggest problem for us is the launcher
                              issue," said Evert Dudok, chief executive of
                              Astrium Satellites of Europe. "The Ariane 5
                              vehicle [Astrium's sister company, Astrium Space
                              Transportation, is the Ariane 5 prime contractor]
                              is increasing its launch rate from seven this year
                              to eight in 2009,
!!! but the other two [principal
                              commercial] vehicles, Sea Launch and Proton, have
                              had a big problem with failures."

22,7 тонны это уже с 4 т полезного груза
сухая масса 3,7т это завышенные цифры, реально будет меньше где-то 3-3,2 т.

В связи с успешным запуском Falcon 1 интересно было бы сравнить с отечественными расценки SpaceX на запуски КА:
Falcon 1:  Price: $7.9M  - LEO Mass to Orbit (185 km circular):  420 kg  
Falcon 9: LEO missions: $36.75M ; TLI missions: $46.75M ;
GTO missions: < 3500 kg  $36.75M; 3500-4500 kg $47.25M; 4500-5000 kg $57.75M .

А у нас сколько :?:

Никто пока не подтвердил эти цифры. Это все пока вилами на воде. Пиар, сэр

[ALEX-Satellite]

Пока только Богатые могут запускать спутники, но есть много Середнячков желающих оплатить и в течение 5-ти лет "отбить" расходы на коммерческий спутник+запуск+управление в размере до $50M.
Хотя, Богатые тоже захотят дешево запускать.
Будем следить за успехами SpaceX.

[Новый]

В этой (или соседней) ветке еще Старым доказывалось, что чем меньше (дешевле) КА, тем меньше шансов отбить его за короткие 3-5 лет, ему для этого нужен почти весь САС.

Если на КА 40-50 эквивалентных стволов, то он отобъется в 2 раза быстрее, чем КА с 10-12 транспондерами. Т.о. берясь за "малый" проект, оператор изначально ставит себя в менее выгодное и более рискованное положение.

[ALEX-Satellite]

Не маленький КА, а дешевый. За счет стандартизации, унификации..., плюс дешевый запуск. А риск есть и с дорогими КА.
В рассматриваемом вопросе акцент сделан на новом игроке рынка запусков - SpaceX декларирующим низкие цены. А уже есть Индийские дешевые платформы. Возможно скоро мы увидим и Середнячков на ГСО. :wink:
