Job description

Develop Guidance, Navigation and Control (GNC) design of the lunar transfer and landing vehicle as keeping the consistency with the overall spacecraft design. Especially be responsible for performing GNC-related analysis and designing detailed GNC algorithm based on the spacecraft requirements. Collaboratively work with software engineers as well as GNC engineers to support algorithm implementation.

月着陸船の姿勢誘導航法サブシステムの開発を行う。GNCに関する設計解析と、上位要求に基づくGNC算術処理則の詳細設計を行う。ソフトウェアエンジニアやGNCエンジニアと協調してアルゴリズムの実装を支援する。

Key Responsibilities

(1) Develop GNC design and perform GNC-related analysis (such as guidance law design and analysis, control law design and performance analysis, navigation filter design, covariance analysis, thruster duty analysis, DV analysis, attitude dynamics analysis, sloshing and flexible dynamics, various GNC sensor testing, etc)
(2) Verify and validate the designed and implemented GNC algorithm by software test and simulation. Support the software test plan and execution for the GNC related functions and evaluate the test result from GNC design perspective. In addition, be engaged in Model-In-the-Loop (MIL), Software-In-the-Loop (SIL) and Processor-In-the-Loop (PIL) simulation campaign and exhaustively validate the design algorithm.
(3) Conduct and support pre-flight analysis activities and participate in flight operation as a member of GNC teams. Develop flight operation plan and support interface design with the ground system from GNC perspective as collaboratively working with the system and operation team
(4) Collaboratively work with the subcontractor on image processing algorithm and vision-based landing algorithm development.

(1) 姿勢制御航法誘導に関する設計解析（誘導制御則設計、制御性能解析、航法フィルタ設計、誤差共分散解析、スラスタ制御解析、DV解析、姿勢力学解析、スロッシング、柔軟ダイナミクス解析、姿勢制御系センサ試験、評価など）を実施する。
(2) ソフトウェア試験およびシミュレーションによりGNCアルゴリズムの妥当性確認および検証を行う。Software-in-the-loop, Processor-in-the-loopなどの静的閉ループ試験を行い、GNCサブシステム設計の妥当性確認と検証を行う。
(3) フライト前解析を行う。GNCチームとして運用に従事する。運用チームとともにGNCの運用計画の立案や運用、軌道計画系とのインタフェース設計や調整を行う。
(4) 画像航法を用いた精密月面着陸のための画像処理アルゴリズムの開発を行う。
