针对多种轨道类型的北斗三号卫星导航系统(BeiDou-3 satellite navigation system ,BDS-3)的反射信号进行极地观测具有独特性,对为期10 d的极地BDS-3反射(BDS-3 reflectometry
BDS-3-R)仿真事件进行分析,并提出了新的时空观测性能评估方法。从卫星轨道高度和倾角两个方面,对BDS-3-R技术在极地观测中的时空性能开展研究。结果表明,在极地区域(纬度高于66.34°)随着卫星轨道高度增加,重访周期变长、空间分辨率逐渐降低。当轨道高度为800 km时,重访周期约为35 h,平均空间分辨率约为17.6 km。同时发现,高轨地球静止轨道卫星有利于极地区域掠射观测事件的产生。此外,随着轨道倾角接近90°,重访周期逐渐变长;当倾角小于80°或大于100°时,BDS-3-R在南北极中心区域存在监测盲区。因此,推荐采用[70°
80°]和[80°
90°]倾角的双星组网方式进行极地观测。分析结果也表明,极地观测趋于采用较大反射天线倾角,且指向方位对反射事件数量有明显影响。
Objectives
2
The polar region is a globally critical area
and its environmental monitoring is vital for climate change research. Given the unique application potential of the BeiDou-3 satellite navigation system (BDS-3) reflectometry (BDS-3-R) technology for polar observation
we aim to systematically evaluate and quantify its spatiotemporal observation performance under various orbital configurations to guide future mission planning.
Methods
2
We take BDS-3 satellites of multiple orbit types as the research objects and conduct a detailed analysis of a 10 d BDS-3-R polar observation simulation event. Based on this analysis
we innovatively propose a new set of spatiotemporal observation performance evaluation methods. Focusing on two core parameters of satellite orbital altitude and orbital inclination
we deeply investigate their influence mechanisms on the polar coverage capability and revisit characteristics of BDS-3-R.
Results
2
The simulation results reveal a close relationship between the spatiotemporal performance in the polar region (latitudes above 66.34°) and the orbital parameters. As the satellite orbital altitude increases
while the observation range may expand
the revisit period correspondingly lengthens
and the spatial resolution significantly decreases. Quantitative analysis shows that at a typical orbital altitude of 800 km
the revisit period is approximately 35 hours
with an average spatial resolution of about 17.6 km. Notably
high-orbit geostationary Earth orbit (GEO) satellites were found to be conducive to generating grazing angle observation events in the polar region. Regarding orbital inclination
the revisit period gradually lengthens as the inclination approaches 90°. More critically
when the inclination is set below 80° or above 100°
the BDS-3-R observations produce distinct monitoring blind zones in the central Arctic and Antarctic regions. Furthermore
the analysis indicates that polar observation missions tend to adopt a larger reflector antenna tilt angle
and the pointing azimuth has a significant regulatory effect on the number of obtainable reflection events.
Conclusions
2
The performance evaluation framework and the quantitative results obtained in this study successfully reveal the optimal orbital configuration for the BDS-3-R system in the polar environment. The study recommends a dual-satellite networking approach with inclinations of [70°
80°] and [80°
90°] for comprehensive polar coverage observation
providing an important theoretical basis and technical support for the orbital design
satellite configuration
and mission planning of future GNSS-R-based polar exploration missions.
