 Key Responsibilities:

  • To define, plan and execute operations to manage the satellite configurations to maintain their health, safety and function
  • To assess and report on satellite health and performance by daily monitoring of their status and monitoring of long-term trends in behaviour of on-board units
  • To respond to satellite contingency situations by assessing satellite status, performing the correct triage, identifying the remedial response and directing recovery operations according to a well-defined incident management process
  • To diagnose problems as quickly as possible, determine the underlying root cause of incidents and identify workarounds or permanent solutions to prevent reoccurrence using techniques such as 8D, 5 whys, fault tree/fishbone analysis to get to the root cause of a problem and then to be able to identify corrective and preventive measures
  • To maintain satellite operational products such as satellite telemetry and telecommand databases, including alarm limits, to support safe and efficient operations and to maintain the routine and contingency satellite control procedures and validate updates against the satellite simulator and maintain the satellite simulators to have a fully representative test bed.
  • To develop and maintain the reference data sets and software applications required by the Spacecraft Analysis Department to perform the satellite health and performance monitoring, operations planning, checking and reporting to ensure early detection of problems
  • To ensure any analyst training plan and accreditation are up to date and when required the provision of any training, definition of courseware and assessments are conducted accurately, effectively and efficiently
  • To work with the Inmarsat and spacecraft manufacturer engineering support teams to investigate anomalies and develop relevant operational solutions.

  • Good PC skills with knowledge of MS Windows, MS Office programs.

 Desirable Knowledge and Skills:

  • Preference for a degree in a Space Engineering related subject,
  • Experience of working with one or more of the following spacecraft platforms: Boeing 702, Airbus E3000, E3KEOR, NEO, TAS Spacebus 4000, Lockheed Martin Series 4000
  • Knowledge of one or more programming languages (e.g. Python, R) to achieve data analysis and data manipulation for trending, anomaly prediction and classification analysis and for developing and enhancing tools for aiding analyst processes and procedures
  • Experience of working with spacecraft manufacturers and satellite engineering support teams for the specification, development and implementation of satellite specific operations for at least one previous geo-synchronous satellite project.
  • Knowledge of the satellite design, build and AIT process
