Bundles ASTOS is composed of several options. Bundles repre-sent a combination of options for dedicated engineering tasks: Launch and Re-entry Simulation and trajectory optimization of conventional and advanced space launchers, suborbital space-planes, sounding rockets and amateur rockets. Re-entry vehicles like capsules and lifting bodies can be optimized as well. Design Vehicle design and trajectory optimization of ascent and re-entry vehicles. It can be extended with propulsion analysis (RPA interface) and with load case analysis for structural mass estimation. GNC Complete platform to analyse open and closed loop AOCS/GNC. It includes the Simulink interface and sensors to consider realistic navigation. It can be extended with flexible dynamics via the “mb linearize” option (DCAP interface). Risk Assessment Analysis of the human risk associated to re-entering vehi-cles considering multiple fragmentations and explosions. It considers the population density, air- and ship-traffic. Monte Carlo analysis can be performed via batch pro-cessing. Launch safety provides automatic procedure to perform a vehicle explosion during the mission evaluat-ing the risk due to fragments and the overpressure due to shock wave. Trajectory Analysis Complete trajectory optimization capability including multiple vehicles and basic mission analysis features (e. g. visibility, link budget, eclipses, life-time, etc. ) Mission Analysis Lite Simulation of scenarios with single spacecraft and ground stations analysing link budget (SNR, C/N0, BER, Data-rate/volume), field of view, visibility of sensors and points of interest, eclipses duration, etc. Ground station visibility during launcher ascent Mission Analysis Complete Augmentation of the capabilities provided by “Mission Analysis Lite” with multiple vehicles (constellations), coverage and navigation. For the coverage it is possible to define the target (e. g. vehicle, ground station, geo-graphical point or region) and the set of conditions (e. g. visibility, link, and relay). The navigation accuracy (e. g. UERE, PDOP, etc. ) is based on GPS, Galileo and GLONASS. System Concept The ultimate solution for all space scenarios including multiple satellites, ascent and re-entry vehicles. It allows the complete vehicle design, the general (continuous and discrete) optimization and the detailed analysis of aspects related to propulsion, power, communication, navigation, thermal, AOCS/GNC and in general mission analysis. This bundle is the perfect tool to assist the project engineer from the proposal preparation till the conclusion of phase B. A must-have for each company that acts as prime contractor.
