Abstract

Observations of ionospheric scintillation using Low Earth Orbit (LEO) Signals of Opportunity (SoOP) offer a unique means of detecting scintillation that are otherwise difficult to capture with traditional GNSS measurements. Radio scintillation in the polar region remains challenging to mitigate, often causing cycle slips, loss of lock in GNSS receivers, and degraded performance in radio communication systems. In this paper, we demonstrate this capability with signals from the METEOR-M No. 2 constellation, transmitting continuously at 137.9 MHz received using a software-defined VHF collection system that was deployed in Gakona, Alaska to record signals during the 2024 Fall season.

极地闪烁监测的低地球轨道信号

利用低地球轨道（LEO）机会信号（SoOP）观测电离层闪烁提供了一种独特的方法来探测闪烁，否则传统的GNSS测量很难捕捉到闪烁。极地地区的无线电闪烁仍然具有挑战性，通常会导致周期跳，GNSS接收器失去锁定，以及无线电通信系统性能下降。在本文中，我们用METEOR-M 2号星座的信号证明了这种能力，该星座使用部署在阿拉斯加加科纳的软件定义VHF收集系统以137.9 MHz的频率连续发射，以记录2024年秋季的信号。

期刊介绍： Radio Science (RDS) publishes original scientific contributions on radio-frequency electromagnetic-propagation and its applications. Contributions covering measurement, modelling, prediction and forecasting techniques pertinent to fields and waves - including antennas, signals and systems, the terrestrial and space environment and radio propagation problems in radio astronomy - are welcome. Contributions may address propagation through, interaction with, and remote sensing of structures, geophysical media, plasmas, and materials, as well as the application of radio frequency electromagnetic techniques to remote sensing of the Earth and other bodies in the solar system.
