Simulation
The simulation activities cover the design, engineering and verification phases of space projects. Space or airborne systems are simulated regarding coverage, revisit-time, repeat cycles, etc. to investigate if the proposed solutions fulfill the mission objectives and the user requirements. As an example for a simulation result Figure 1 shows the access pattern of a target for different satellite systems. Orbit selections are analyzed and optimized to obtain the best coverage and revisit cycles for specific areas of interest. Mission simulations using realistic user scenarios are performed to receive information about imaging capacity and system limitations under operational conditions considering manoeuvres and service intervals, power and data storage constraints. As part of mission design Figure 2 illustrates the analysis for a satellite attitude control system.
