Swiss Space Systems (S3) is a company which plans to provide orbital launches of miniaturized satellites and manned suborbital spaceflights. The company is based in Payerne in western Switzerland, near Payerne Air Base, where it plans to build a spaceport in 2015. Suborbital spaceplanes will be launched from an Airbus A300, giving the spacecraft more initial speed and altitude than if it were launched from the ground.
