Projekt SCD2-A, Preliminary Orbit Analysis

Kurzfassung

The SCD2-A Satellite was proposed to be launches with the first Brazilian carrier vehicle VLS. This satellite is geometrically similar to SCD1, that is in orbit for near 7 Years, and is used for data collection. The SCD2-A also intend to be the spare of SCD2, that will be launched in the near future, may be by the American rocket Pegasus. All this versions have more or less the same characteristic: Mass 115 kg; Attitude: Spin stabilized; Orbit altitude: 750 km (near circular); Inclination: 25 deg (SCD1 & SCD2) and 16 deg (SCD2-A) The intention of this report is to present the preliminary study for the orbit for the SCD2-A, using the injection conditions and disperdons proposed by the carrier. All simulations present her, was produces using the software package developed and implemented at DLR/GSOC, called Veni, Vidi and Vici. (ref. 2, 3, 4) and Modeas (ref. 6).
