The constellation Skylark will be the first commercial mission focused on Space Situational Awareness (SSA), that is, the monitoring of assets in low, medium and high orbits to provide information on space traffic, avoid collisions and supply timely and accurate navigation services to the entire satellite community. It was conceived by the start-up NorthStar Earth & Space, created three years ago by Telesystem Space (a joint venture of the family office Sirois, Telesystem and the Roger's Family Trust of Canada), Space Alliance (Thales Alenia Space and Telespazio) of Europe, KinetX (from the United States), the Government of Quebec and the Government of Canada.
