Mission Design for the CubeSat OUFTI-1

CHAPTER 5Typically, the AVUM burns three times: the first to place the satellite andhimself into an elliptical orbit with the apogee at the target altitude, the secondto raise the perigee to the required value or for orbit circularization and thethird for deorbiting himself. Jettisoning of the payload fairing can take place atdifferent times, depending on the aero-thermal flux requirements on the payload,but normally it happens between 200 and 260 seconds from lift-off.5.1.2 PerformancesVega is designed to launch a wide range of missions and payload configuration:in particular, it can place in to orbit masses ranging from 300 to 2500 Kg intoa variety of orbit, from equatorial, to sun synchronous and polar. Its performancesare shown in figure 5.4.Figure 5.4: Vega performances: payload mass as a function of orbit inclinationand altitude required.Vega can also operate the launch of multiple payloads.5.1.3 Launch CampaignThe spacecraft launch campaign formally begins with the delivery in CSG of thespacecraft and its associated Ground Support Equipments (GSE), and concludeswith GSE shipment after launch. It cannot exceed 30 days: 27 days beforelaunch and 3 days after it.A typical launch campaign can be divided in three parts:1. Spacecraft autonomous preparationIt includes all the operations conducted from the spacecraft arrival to theCSG up to the readiness for integration with the launch vehicle.Galli Stefania 28 University of Liège
