Abstract

This work introduces the problem of initial orbit determination (IOD) from only heading measurements. Such a problem occurs in practice when estimating the orbit of a spacecraft using visual odometry measurements from an optical camera. After reviewing the problem geometry, a simple solution is developed in the form of an iterative scheme on the parameters describing the orbital hodograph. Numerical results are presented for an example spacecraft in low lunar orbit. The principal intent of this brief study is to communicate the existence of a new class of IOD problem to the community and to encourage the broader study of hodographs and heading-only IOD.

仅根据航向测量确定初始轨道

本文介绍了仅通过航向测量来确定初始轨道的问题。在实际应用中，当使用光学相机的视觉里程计测量来估计航天器的轨道时，就会出现这样的问题。在回顾了问题的几何学之后，以描述轨道轨迹的参数的迭代格式的形式提出了一个简单的解决方案。给出了一个月球低轨道实例的数值计算结果。这项简短研究的主要目的是向社区传达一种新的IOD问题的存在，并鼓励更广泛地研究hodographs和标题式IOD。

期刊介绍： This Journal, that started it all back in 1963, is devoted to the advancement of the science and technology of astronautics and aeronautics through the dissemination of original archival research papers disclosing new theoretical developments and/or experimental result. The topics include aeroacoustics, aerodynamics, combustion, fundamentals of propulsion, fluid mechanics and reacting flows, fundamental aspects of the aerospace environment, hydrodynamics, lasers and associated phenomena, plasmas, research instrumentation and facilities, structural mechanics and materials, optimization, and thermomechanics and thermochemistry. Papers also are sought which review in an intensive manner the results of recent research developments on any of the topics listed above.
