About This Position
Spacecraft Descent Guidance, Navigation, and Control System Engineer
Define requirements for the GNC subsystem, including sensors, software and other hardware components, and manage technical coordination and interface alignment with other subsystems.
Manage the integrity and performance of GNC algorithms in the FSW development and deliverables. Support mission operations and preparation activities.Key responsibilities
(2) Design the Entry, Descent and Landing (EDL) GNC functions and perform GNC-related analyses (such as guidance law design and analysis, control law design and performance analysis, thruster duty analysis, DV analysis, attitude dynamics analysis, sloshing and flexible dynamics, navigation filter design, covariance analysis, various GNC sensor evaluation, etc) by using control engineering tools and in-house developed software.
(3) Plan, implement, and execute comprehensive verification and validation (V&V) activities for the landing system, spanning from component-level (GNC sensors) to system-level tests (SCLT, DOLT, DCLT).
(4) Design frameworks for the GNC FMECA (Failure Mode, Effects, and Criticality Analysis) and MCFMA (Mission Critical Fault and Mitigation Analysis) methodologies and execute fault scenarios for validating landing operations robustness.
(5) Develop a deep understanding of GNC subsystem requirements, design, constraints, and operations — including vision-based navigation — and manage technical coordination and interfaces alignment with systems engineering and other subsystems (propulsion, structures, thermal, avionics, flight software, mission planning, and operations).
(6) Define landing GNC flight software/algorithm requirement specifications
(7) Define landing GNC unit specifications as flow-down of the GNC system requirements and design specifications.
(8) Support lander system design with providing GNC feasibility studies and design inputs for the key system design trade-offs such as actuator and sensor configuration and selection, component layout, controllability, delta V, RCS budget, etc.
(9) Support the selection, verification, and operational readiness of key orbiter system components — such as IMUs, star trackers, LiDARs, cameras and propulsion — from both technical and theoretical perspectives.
(10) Design and support troubleshooting activities of GNC FSW algorithms and components and propose solutions to mitigate errors and misbehaviors in the GNC subsystem.
(11) Document the technical specifications of the GNC subsystem with a deep understanding of the functions and relations with other subsystems.
