Talk:Atlas V Rocket Launches with Inmarsat Satellite/Notes

http://www.ilslaunch.com/launches/cbin/Mission_Overview/atlas/INMARSAT_4F1_MO.pdf

The Atlas V 431 launch vehicle will place the EADS Astrium-built Inmarsat 4-F1 satellite into orbit for Inmarsat. The Atlas V launch vehicle will lift off from Launch Complex 41 at Cape Canaveral Air Force Station, Florida. The super-synchronous transfer orbit mission design will use a parking orbit ascent trajectory design with two Centaur burn phases. The satellite's attitude and orbital control system will perform a series of burns to raise perigee and reduce apogee to circularize the orbit, while also reducing inclination, thus placing the spacecraft into a geosynchronous orbit. The duration of the mission, from liftoff to satellite separation, is approximately 32 minutes.

Atlas V 431 4 = meters of diameter of upper stage 3 = number of solids 1 = number of engines on centaur

Payload: Inmarsat 4-F1 Geosynchronous multi-use communications satellite Separated mass: Approx. 5,945 kg (13,106 lbs)

Satellite Use: First in next generation of satellites, which will support Inmarsat’s new Broadband Global Area Network (BGAN), delivering internet and intranet content and solutions, video-on-demand, videoconferencing, fax, e-mail, phone and LAN access at speeds up to 432kbit/s almost anywhere in the world. BGAN will also be compatible with third-generation cellular systems

Mission Profile: Atlas V will place Inmarsat 4-F1 into orbit with a super-synchronous transfer orbit mission, using a parking orbit ascent trajectory design with two Centaur burn phases. The mission employs a guidance-commanded shutdown. The satellite’s own attitude and orbital control system will perform a series of burns to lower apogee and raise perigee to geosynchronous altitude, circularize orbit and reduce inclination.

To support Atlas V missions, a new state-of-the-art launch site Launch Complex 41 was constructed at Cape Canaveral Air Force Station, Florida. The new launch site consolidates the support facilities to two, Atlas Spaceflight Operations Center and Vertical Integration Facility, plus a Mobile Launch Platform and introduces the clean pad concept to U.S. launch capabilities for the first time. The new facilities were designed and built with customer needs, comfort, and efficiency in mind.

The clean pad concept of LC 41 allows for greater flexibility in launch operations. This new system provides for the Atlas V to be assembled, tested and mated with the encapsulated spacecraft at the Vertical Integration Facility (VIF).

Accommodations at the VIF include a level 5, 100,000-class clean work area, a 60-ton bridge crane and personnel platform to support integration tasks. Services to the launch vehicle include air conditioning, conditioned gas, and power and data transmission through the range fiber network.

The Atlas V is integrated onto and launched from a Mobile Launch Platform (MLP). The MLP is moved into the VIF for integration, then transports the Atlas V in launch configuration to the pad where final propellants are loaded and countdown commences. The clean pad concept allows the Atlas V to be rolled to the launch pad approximately 14 hours before launch versus the weeks needed for processing the Atlas IIs and IIIs on LC 36. Reduced time on the pad allows for more flexibility in meeting customer launch needs.
