• Monitor manoeuvre performance and propellant consumption to continuously refine, optimize, and update the satellites’ operational life estimates. Derive algorithms and implement tools to improve data trending and satellite manoeuvre life calculations.
• Support occasional special satellite operational activities which include, but are not limited to geosynchronous satellite relocation, deorbiting a satellite, satellite launches, and orbit transfers.
• Participate in flight dynamics software maintenance, development, enhancement, and testing.
