Fuel-optimal Boost-Back Guidance via Successive Convexification with a Terminal Constraint for ReusableLaunch Vehicles
Mingyeom Kim, Changhyun Kang, Dohyun Lee +1
This paper proposes a fuel-optimal boost-back guidance algorithm for reusable launch vehicles using successive convexification (SCvx). The guidance problem is formulated as a free-…
A Semi-analytic Method for Rapid Coverage Analysis of a Satellite Using Piecewise Ellipse Models
Byeong-Un Jo, Jinsung Lee
Satellite coverage analysis commonly relies on intensive numerical computations to evaluate access and revisit times, resulting in high computational costs, particularly in long-te…
Terminal Soft Landing Guidance Law Using Analytic Gravity Turn Trajectory
Seungyeop Han, Byeong-Un Jo, Koki Ho
This paper presents an innovative terminal landing guidance law that utilizes an analytic solution derived from the gravity turn trajectory. The characteristics of the derived solu…
Time Efficient Rate Feedback Tracking Controller with Slew Rate and Control Constraint
Seungyeop Han, Byeong-Un Jo, Koki Ho
This paper proposes a time-efficient attitude-tracking controller considering the slew rate constraint and control constraint. The algorithm defines the sliding surface, which is t…
Optimal Strip Attitude Command of Earth Observation Satellite using Differential Dynamic Programming
Seungyeop Han, Byeong-Un Jo, Koki Ho
This paper addresses the optimal scan profile problem for strip imaging in an Earth observation satellite (EOS) equipped with a time-delay integration (TDI) camera. Modern TDI came…
