[[NASA]] provided the [[Delta II]] launch vehicle to launch RADARSAT-1 and access to the [[NASA Deep Space Network]] (NASA DSN) in exchange for access to its data. Estimates are that the project, excluding launch, cost CA$620 million. The Canadian federal government contributed about CA$500 million, the four participating provinces ([[Quebec|Québec]], [[Ontario]], [[Saskatchewan]] and [[British Columbia]]) about CA$57 million, and the private sector about CA$63 million.

RADARSAT International, Inc. (RSI), a Canadian private company, was created in 1989 to process, market and distribute RADARSAT-1 data. (RADARSAT International, Inc. (RSI) was later acquired by [[MacDonald Dettwiler|MacDonald Dettwiler and Associates]].) In 2006, RSI was rebranded MDA Geospatial Services International or MDA GSI.
