语境。欧洲航天局的火星快车航天器对火星卫星火卫一进行了有史以来最接近的飞越，为研究行星卫星系统提供了一个独特的机会来加强和测试行星无线电干涉测量和多普勒实验（PRIDE）技术。目标。这项工作的目的是展示一种使用火星快车航天器对行星航天器提供高精度位置和多普勒测量的技术。该技术将在各种行星任务中的行星无线电干涉测量和多普勒实验框架中使用，特别是在飞越模式下。方法。我们利用多普勒和相位参考超长基线干涉测量航天器跟踪技术，提出了一种新颖的航天器数据处理方法。结果。平均而言，我们实现了径向三向多普勒估计的 mHz 精度（10 s 积分时间为 30 μm/s）和横向位置测量的亚纳弧度精度，在线性测量中（距离为 1.4 AU）相当于约 50 m。
Context. The closest ever fly-by of the Martian moon Phobos, performed by the European Space Agency’s Mars Express spacecraft, gives a unique opportunity to sharpen and test the Planetary Radio Interferometry and Doppler Experiments (PRIDE) technique in the interest of studying planet–satellite systems. Aims. The aim of this work is to demonstrate a technique of providing high precision positional and Doppler measurements of planetary spacecraft using the Mars Express spacecraft. The technique will be used in the framework of Planetary Radio Interferometry and Doppler Experiments in various planetary missions, in particular in fly-by mode. Methods. We advanced a novel approach to spacecraft data processing using the techniques of Doppler and phase-referenced very long baseline interferometry spacecraft tracking. Results. We achieved, on average, mHz precision (30 μm/s at a 10 s integration time) for radial three-way Doppler estimates and sub-nanoradian precision for lateral position measurements, which in a linear measure (at a distance of 1.4 AU) corresponds to ~50 m.
