What you will do

• Develop orbiter GNC design and perform related analysis using control engineering tools, including guidance/control laws, thruster duty, DV, attitude dynamics, navigation filters, and sensor evaluation.
• Verify and validate GNC algorithms via software tests and simulations from unit to system level, including MIL, SIL, PIL, and HIL campaigns.
• Conduct pre-flight, in-flight, and post-flight analysis; develop operation procedures and support ground system interfaces as part of orbiter GNC team.
• Perform troubleshooting of GNC flight software algorithms and propose solutions for errors.
• Document technical specifications of GNC subsystem with understanding of inter-subsystem relations.
• Support development studies for future space vehicle missions.
