AXA’s Arase Spacecraft, which is formerly known as Exploration of Energization and Radiation in Geospace (ERG), was launched on 20 December 2016. The spacecraft is spin-stabilized. Its mission is exploring how relativistic electrons in the radiation belts are generated during space storms. Two on-ground attitude determination algorithms are considered for the mission: a conventional simple algorithm that inherits from old missions and an advanced algorithm that is newly designed. This paper discusses the design of the advanced attitude determination algorithm. The algorithm is composed of three main parts: the coarse attitude estimator, star identification and tracking algorithm, and the fine attitude estimator. In this paper, we present the essentials of each algorithm and describe how they are put together to form the advanced attitude determination suite for Arase.

Mission Experience for Spinning Spacecraft Attitude Filtering with Spin Parameters Söken, Halil Ersin; Asamura, Kazushi; Nakamura, Yosuke; Takashima, Takeshi; Shinohara, Iku (2019-06-21) JAXA's Arase Spacecraft, which is formerly known as Exploration of Energization and Radiation in Geospace (ERG), was launched on 20 December 2016 and has been in orbit for almost 3 years. The spacecraft is spin-stabilized. Its mission is exploring how relativistic electrons in the radiation belts are generated during space storms. Two on-ground attitude determination algorithms are used for the mission: a conventional simple algorithm that inherits from old missions and an advanced algorithm that is newly d...
Filtering-Based Three-Axis Attitude Determination Package for Spinning Spacecraft: Preliminary Results with Arase Söken, Halil Ersin; Asamura, Kazushi; Nakamura, Yosuke; Takashima, Takeshi; Shinohara, Iku (2020-07-01) JAXA's ERG (Exploration of Energization and Radiation in Geospace) Spacecraft, which is nicknamed Arase, was launched on 20 December 2016. Arase is a spin-stabilized and Sun-oriented spacecraft. Its mission is to explore how relativistic electrons in the radiation belts are generated during space storms. Two different on-ground attitude determination algorithms are designed for the mission: A TRIAD-based algorithm that inherits from old missions and a filtering-based new algorithm. This paper, first, discus...
Spinning Spacecraft Attitude Filtering with Spin Parameters: Performance Evaluation with Real Data Söken, Halil Ersin; Van Der Ha, Jozef C. (null; 2017-06-07) Three-axis attitude estimation for spinning spacecraft is recently of considerable practical interest. In this scope, sequential filtering algorithms are also being studied recently. In this study, we extend our recent research for a nonlinear filtering algorithm for spinning spacecraft attitude estimation. In the filter the attitude of the spacecraft is represented using a set of spin parameters. These parameters consist of the spin-axis orientation unit vector in the inertial frame and the spin phase angl...
Nonlinear tracking attitude control of spacecraft on time dependent trajectories Tekinalp, Ozan; Atas, Omer (2015-08-13) The spacecraft attitude control is carried out using the to-go quatemion. A derivative of the to-go quaternion is derived where the desired attitude is a time dependent function. Based on this new attitude formulation, a proper state dependent coefficient matrix expression is obtained. Then the nonlinear tracking attitude control is realized using the state dependent Riccati equation method. The simulation results are given and discussed.
Exploration of energization and radiation in geospace (ERG): challenges, development, and operation of satellite systems Nakamura, Yosuke; et. al. (2018-06-01) The exploration of energization and radiation in geospace (ERG) satellite, nicknamed "Arase," is the second satellite in a series of small scientific satellites created by the Institute of Space and Astronautical Science of the Japan Aerospace Exploration Agency. It was launched on December 20, 2016, by the Epsilon launch vehicle. The purpose of the ERG project is to investigate how high-energy (over MeV) electrons in the radiation belts surrounding Earth are generated and lost by monitoring the interaction...
