Sea Launch Co. LLC has begun final preparations for the launch of the Inmarsat-4 satellite Nov. 5, Sea Launch announced. The mission was scheduled to be launched Nov. 4, but conditions in the Pacific Ocean delayed the arrival of the company’s launch platform at the equatorial launch site, Sea Launch spokeswoman Paula Korn told Satellite Today.

The EADS Astrium-built Inmarsat-4 F2 satellite, which will reside at 53 degrees West, is the second spacecraft designed to support Inmarsat‘s Broadband Global Area Network (BGAN) services. Inmarsat 4-F1 was placed into orbit in March. The satellites carry a single global beam that covers up to one-third of the Earth’s surface, 19 wide spot beams and 228 narrow spot beams. BGAN delivers Internet and intranet content, video on demand, videoconferencing, fax, e-mail, phone and local area network access at speeds of up to 500 kilobits per second to BGAN terminals.

The launch window for the Inmarsat-4 F2 is set to open at 9:18:55 a.m. EST and last for 29 minutes. Sea Launch will broadcast a streaming video feed of the launch on its Web site (http://www.sea-launch.com/current_index_webcast.html) beginning at 9 a.m. PST.
