LAUNCH VEHICLE INTERFACES AND LAUNCH SUPPORT ACTIVITIES. The Contractor is required to provide a common satellite design which is fully compatible with a minimum of two different launch vehicles. This compatibility shall include all mechanical and electrical interfaces, envelope, lift-off mass, safety and all other aspects concerned with the launch. Inmarsat will procure these launch vehicle services directly from one or more of the launch vehicle service providers from the following list:- Ariane 5 Sea-Launch Delta 4 Atlas 5 Proton Breeze M The selection of two launch vehicles shall be completed within twelve months from the contract award for the satellite programme. The final launch vehicle selection for a particular satellite shall be made by Inmarsat in a time-frame consistent with the AI&T activities associated with launch vehicle compatability for that satellite and in any case no later than 2 months prior to the agreed need date for that satellite. The Contractor will be required to perform all the launch vehicle technical design and interface activities required by these selected launch service providers and all other activities required to ensure complete compatibility with the selected launch vehicles; for the submission of any integration documentation required by these launch vehicle agencies, and for obtaining the information necessary to demonstrate compliance with their requirements. The Contractor shall be responsible for pre-launch operation tasks at the launch site as described in Appendix 1 to this SOW, entitled Launch Vehicle Support Requirements. The satellite design shall facilitate the possibility to switch from one launch vehicle to another at a late stage in the manufacturing process for any given satellite in order to accommodate late changes in availability for a particular vehicle.
LAUNCH VEHICLE INTERFACES AND LAUNCH SUPPORT ACTIVITIES. The Contractor shall perform all the launch vehicle technical design and interface activities required by the selected launch service providers. Upon selection of a launch vehicle, the Contractor will perform the fit check,, pyrotechnic release tests and other activities required to ensure complete compatibility with the selected launch vehicle. The Contractor shall be responsible for the submission of any integration documentation required by these launch vehicle agencies, and for obtaining the information necessary to demonstrate compliance with their requirements. The Contractor shall be responsible for pre-launch operation tasks at the launch site as described below: • transportation of the spacecraft to the launch site; • handling and operation of the spacecraft and spacecraft test equipment during the launch operations; • assembly and checkout activities, such as those related to batteries, solar arrays, pyrotechnic devices, propulsion subsystem propellant filling and pressurisation, and spacecraft checkout; • supply of propellants and pressurants as required for the mission; • transportation of the satellite at the launch site where not provided by the launch vehicle agency; • participation in launch operation rehearsals; • provision of a compatibility test with the SCC for the satellite; • recovery operations after an aborted launch and performing all operations necessary to prepare the spacecraft for launch again; • recovery of spacecraft hazardous equipment if recoverable after a launch failure; Contract No:07-4471 • disposal of hazardous waste from spacecraft launch preparation, such as surplus fuel; • support to Inmarsat during the launch campaign in meetings to review progress, to identify and resolve interface or facility issues and also in the Acceptance and Launch Readiness Reviews; • to demonstrate compliance with the safety requirements of the launch vehicle agencies; • to provide voice and data communications links from the launch site to the SCC in London, in order to monitor satellite telemetry up to the moment of launch; • mass properties; • alignment; • integration with adapter and launch vehicle. The satellite design shall facilitate the possibility to switch from one launch vehicle to another at a late stage in the manufacturing process in order to accommodate late changes in availability for a particular vehicle. This possibility will be maintained up to ****.
