 Yeah, I think that there's a contract, but there is an obligation of an OEM, so an original, a pre-manufactured satellite maker, with the launcher. So depending on which launcher you use, if you use a SpaceX or if you use a Starlink or if you use a Vega or a Rian, it doesn't matter where you launch, each of them will give you some load, some harshness, some vibration, and some noise that you have to make sure you're able to withstand.
