9 CONCLUSION As a PRIME for space transportation & along years, -ST has developed its own astrodynamics tools for its customers and their project needs. Those cover a wide space transportation spectrum, The tools for operationnal or in-development vehicles have been approved by customer experts to be certified as reference tools (e.g. ONERA, LRBA, CNES benchmarks ) The major ones are flight qualified. Flexibility and autonomy on mission analysis tools is key for -ST. Continuous efforts are thus made to sustain customer project needs & our own R&Ds for independant mission analysis purposes, based on home or commercial core optimizers.
