  • Overview

    The PTR Group – wholly owned subsidiary of the Fulcrum is seeking a Spacecraft Guidance, Navigation, and Control (GNC) Engineer to join our team supporting Northrop Grumman Innovations Systems, Inc. formerly known as Orbital ATK developing cutting edge space technology solutions.

    Responsibilities

    We are seeking a motivated candidate that will fill the position of Spacecraft Guidance, Navigation, and Control (GNC) engineer.  A spacecraft GNC engineer is responsible for contributing to the design, analysis, and testing of the GNC subsystem for the space vehicle.  A spacecraft GNC engineer will work within the GNC subsystem team and under the supervision of the GNC subsystem lead.  A spacecraft GNC engineer is expected to:

     

    • Design, analyze, and tune spacecraft attitude and position control loops using time and frequency domain techniques
    • Design, analyze, and tune sequential filters (e.g. Kalman filters) for attitude determination and relative navigation
    • Analyze and test the spacecraft GNC subsystem performance using simulations and other analytic tools
    • Implement GNC algorithms in flight software and support flight software qualification testing
    • Perform analysis to support early design phase concept development including actuator sizing and placement, sensor selection and placement, and predicted performance assessments
    • Develop simulation models for sensors (e.g. star tracker, rate gyro, accelerometer, GPS, magnetometer, sun sensors), actuators (e.g. reaction wheel, torque bar, thruster, CMG), system dynamics (e.g. rigid body, multi-body, orbit mechanics, flexible models), and the space environment (e.g. atmospheric, solar radiation pressure, third-body gravity, geopotential)
    • Apply engineering principles, industry standards, company process, and knowledge of vehicle dynamics, aerodynamics, propulsion, classical/modern control, and estimation theory to perform tasks to advanced program/project goals
    • Document designs, analysis, and test results and create presentation materials
    • Present designs, analysis, and test results to internal and external customers
    • Work well within small- to medium-sized groups

    Qualifications

    Minimum Requirements: 

    • Minimum 3 years experience
    • Proficiency in MATLAB/Simulink and C/C++
    • Experience in spacecraft GNC subsystem design, analysis, and testing
    • Experience implementing GNC algorithms on embedded systems
    • Strong verbal and written communications skills
    • Strong interpersonal skills
    • Strong analytical skills

    Education: 

     

    • MS or PhD degree in engineering, physics, or math

    Clearance Requirements: 

     

    • Top Secret Security Clearance preferred with a valid background investigation
    • Current SCI Clearance preferred
