Gov. Robert F. McDonnell announced Monday that the world’s leading provider of satellite services is moving its U.S. headquarters from the District to Fairfax County.

Intelsat will move at least 430 employees to Tysons Tower in McLean in mid-2014. The company will lease approximately 188,000 square feet at the site, which is under construction.

McDonnell approved a $1.3 million grant from the Governor’s Opportunity Fund to assist Fairfax County with snagging the headquarters. The Virginia Economic Development Partnership also worked with the county.

Fairfax County Economic Development Authority President and Chief Executive Officer Gerald L. Gordon said the deal helps “diversify our economy ... at a time when government contracting and some other industry segments have slowed.”

McDonnell made the announcement Monday in McLean. According to a statement released by the governor’s office Monday, Intelsat is a 45-year old company that delivers information and entertainment for many of the world’s leading media and network companies, multinational corporations, Internet service providers and governmental agencies.

Intelsat Chief Executive Officer David McGlade said in a statement that the company’s choice to relocate in Virginia required “access to well-educated professionals, a first-class transportation system and compelling amenities.”
