Mission Analysis Expert

2015-03-30 17:05:52| Space-careers.com Jobs RSS

RHEA is currently recruiting a Mission Analysis Expert to work on selected terrestrial and interplanetary missions at our clients premises in Darmstadt, Germany. Tasks and Activities The scope of work will include Definition, assessment and feasibility studies for terrestrial and interplanetary missions. For specific questions, support is also given during the operational phase of the mission and for endoflife disposition of space systems. A few typical tasks are the following Launcher requirements Analysis of launcher trajectory and launcher performance Tradeoffs for the selection of the operational orbit Launch window analysis Short and longterm orbit evolution Lifetime calculation Orbit manoeuvres and navigation Accuracy of orbit determination Parameter estimation Calculation of propellant budgets Lowthrust trajectory optimization Analysis of geometrical events groundstation visibility, eclipse, sky coverage Operations planning and scheduling Optimization of scientific return Endoflife disposition. Computation of the various terrestrial and planetary satellite orbits low earth, geostationary, highly eccentric, interplanetary trajectories and planetary orbiters. Depending on the type of orbits and the required accuracy, various numerical and analytical methods are used. Various additional information is needed pertaining to the spacecraft or to the ground, such as visibility periods from the groundstations, eclipse times or coverage by imaging instruments. In order to rationalize the effort many similar calculations for terrestrial or planetary satellites or interplanetary probes are performed using standard systems developed by the group over many years. Examples of these systems are USOC the Unified System for Orbit Computation that allows in an interactive manner to set up programs tailored to specific tasks by selecting automatically the required modules. INTNAV Interplanetary Navigation is a system used for the analysis of navigation accuracy and requirements. Both USOC and INTNAV have a Graphical User Interface based in TclTk. LOTNAV Has the same purpose as INTNAV but when low thrust is used. DITAN Generation and optimisation of low thrust trajectories MANTRA High fidelity and flexible generation and optimisation of chemical propulsion and low thrust trajectories In HSOGFA numerous standalone programs are in use for the solution of various particular tasks, such as orbit determination, orbit control, orbital manoeuvres, optimization of rocket ascent trajectories, optimum acquisition of the operational orbit, optimization of mission performance, mission planning and reentry calculations. Frequently upgrading or modifications is needed on the individual programs. Introduce new analytical and numerical methods for new projects that require unconventional orbits andor very specific mission requirements. Developing new algorithms, solutions and auxiliary calculations. Such modules or programs can be incorporated in an easily accessible SW library. Design of proper interfaces, careful testing and the preparation of documentation is mandatory. Skills and Experience The following skills and experience are mandatory Mathematical and stochastic methods and processes Classical and Celestial Mechanics Spacecraft Dynamics Applied Mathematics Relevant Space Environment modelling Relevant satellite systemspayload e.g. AOCS, star trackers, propulsion control Satellite Tracking techniques Software Engineering Orbit dynamics Orbit determination and prediction Operations support for flight dynamics.
