Skyroot Aerospace and Bellatrix Aerospace have signed a Memorandum of Understanding (MoU) to use the Orbital Transfer Vehicle being developed by Bellatrix Aerospace in the upper stage of Vikram series of launch vehicles being developed by Skyroot. An Orbital Transfer Vehicle is a spacecraft that can perform various in-orbit operations including deployment of customer payload to precise orbits, allowing a launch vehicle to deliver satellites to more orbits than what was conventionally possible. In simple terms, it is like a taxi in space to take satellites to their operational orbits. Skyroot and Bellatrix plan to have the first mission of a Vikram launcher with an Orbital Transfer Vehicle by 2023.
