Abstract

Spaceborne global navigation satellite system (GNSS) has significantly revolutionized the development of autonomous orbit determination techniques for low Earth orbit satellites for decades. Using a state-of-the-art combination of GNSS observations and satellite dynamics, the absolute orbit determination for a single satellite reached a precision of 1 cm. Relative orbit determination (i.e., precise baseline determination) for the dual satellites reached a precision of 1 mm. This paper reviews the recent advancements in GNSS products, observation processing, satellite gravitational and non-gravitational force modeling, and precise orbit determination methods. These key aspects have increased the precision of the orbit determination to fulfill the requirements of various scientific objectives. Finally, recommendations are made to further investigate multi-GNSS combinations, satellite high-fidelity geometric models, geometric offset calibration, and comprehensive orbit determination strategies for satellite constellations.

利用全球导航卫星系统精确确定低地球轨道卫星的轨道：观测、模型和方法

几十年来，空间全球导航卫星系统（GNSS）极大地推动了低地球轨道卫星自主轨道测定技术的发展。利用最先进的全球导航卫星系统观测和卫星动力学组合，单颗卫星的绝对轨道测定精度达到了 1 厘米。双卫星的相对轨道测定（即精确基线测定）精度达到了 1 毫米。本文回顾了全球导航卫星系统产品、观测处理、卫星引力和非引力建模以及精确轨道测定方法的最新进展。这些关键方面提高了轨道测定的精度，以满足各种科学目标的要求。最后，提出了进一步研究多全球导航卫星系统组合、卫星高保真几何模型、几何偏移校准和卫星星座综合轨道确定战略的建议。
