Shape the future of military satellite communications and help protect critical national capabilities.
At Babcock, we’re working to create a safe and secure world, together. If you join us, you can play your part as a Principal Flight Dynamics Engineer at Hawthorn, near Chippenham, Wiltshire.
The role
As a Principal Flight Dynamics Engineer, you'll join a mission-critical team supporting the UK’s current and next-generation military geostationary spacecraft constellation. This is a rare opportunity to apply your expertise to highly complex satellite operations that directly contribute to national security and defence capability.
Working as part of a collaborative multi-company operations team, you'll help ensure the highest levels of availability across the Military Satellite Communications programme. From orbit determination and manoeuvre planning through to satellite life optimisation and operational support, your work will have a direct impact on mission success. You'll also have the opportunity to contribute to cutting-edge space operations while further developing your technical expertise in a highly specialised and growing area of aerospace engineering.
Day-to-day, you’ll be required to:
- Perform orbit determination and plan the manoeuvres necessary to maintain the positions of the UK Military Satellite Communications geosynchronous satellite fleet.
- Perform on-call support responsibilities, when required.
- Support daily flight dynamics operations, including orbit determination, manoeuvre planning, and product generation.
- Support detail data and trending analysis for the Military Satellite Communications fleet.
- Maintain accurate accounting of propellant.
- 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.
