In this paper, we present the in‐orbit verification of a dynamic link budget approach for the communication link of the Eu:CROPIS (Euglena and Combined Regenerative Organic‐Food Production in Space) satellite. Because of the high satellite spin rates of up to 30 rpm, the satellite antennas radio frequency beam becomes strongly dynamic, consisting of fast amplitude variations and phase rotations. Both effects degrade the link quality and might lead to an abort of the communication. The paper presents an accurate method of how to simulate these dynamic effects and examines the simulation outputs with real in‐orbit measurements. Both results are compared with each other, and deviations are discussed.

自旋稳定卫星任务Eu：CROPIS的动态链接分析及其在轨验证

在本文中，我们介绍了Eu：CROPIS（Euglena和空间再生有机食品联合生产）卫星通信链路的动态链路预算方法的在轨验证。由于高达30 rpm的高卫星自旋速率，卫星天线的射频波束变得非常动态，包括快速的幅度变化和相位旋转。这两种影响都会降低链路质量，并可能导致通信中断。本文提出了一种如何模拟这些动态效果的精确方法，并通过实际在轨测量来检查模拟输出。将两个结果相互比较，并讨论偏差。
