Developing a Multi-Frequency for GNSS-Based Scintillation Monitoring Receiver

James T. Curran, Michele Bavaro, Aiden Morrison, Joaquim Fortuny

Abstract:	The design, development and deployment of a multi-frequency scintillation-monitoring GNSS receiver is presented in this paper. To provide a large degree of flexibility and reconfigurability, the receiver is comprised of a custom quad-channel front-end, a software-defined receiver and post-processor utility. This configuration enables raw IF data capture, near-real-time or post-mission processing, and event identification for dataset archiving. The performance of this final design is benchmarked against a set of commercial atmospheric monitoring receives, using datasets recorded at both equatorial and high-latitude sites. Focusing on the availability and consistency of intensity and phase scintillation metrics, namely ?? and S4, results demonstrate comparable performance both in the absence and presence of exhibiting high ionospheric scintillation.
