NBN Co. can now rest easy knowing that its plans to launch two satellites are following the correct approvals process of the world satellite body, the United Nations communications agency.

The satellites will be used by NBN Co to deliver broadband in remote regions of Australia.

According to the Geneva-based International Telecommunications Union (ITU), despite NBN Co. not yet finalising the positions in orbit over Australia for the satellites, it is not uncommon for a company to purchase satellites beforehand.

"It is possible for a company to purchase a satellite in advance of it being put into use and the orbital slots being finalised," the agency said in a prepared statement.

"In order to secure those slots the notifying authority, which in Australia is the Australian Communications and Media Authority, needs to (a) initialise the registration procedure with the ITU, and (b) resolve any major compatibility issues with operators of neighbouring satellites."

The ITU added that as long as "there are no regional objections and the ITU registration process is underway, an operator can proceed with its launch plans."

NBN Co has been proactively pursuing the ITU international frequency coordination process since August 2010, with NBN. Co CEO Mike Quigley recently announcing that he expects that the "formalities will be completed" before the satellites are launched in 2015.
