Abstract

The High Frequency Receiver System (HFRS) is a mobile, autonomous, Linux-based RF recording system that is designed to pick up ionosonde sounding signals from 1—10 MHz. Systems are designed for quick deployment and capable of remaining deployed in the field for up to a month. The design motivation was for ionospheric sounding campaigns in New Mexico organized by the Air Force Research Labora- tories (AFRL). The systems are calibrated to selected sites and thus require Radio Frequency Interference (RFI) characterization of the sites. The project includes building and using four standalone systems with associated power, antenna, RF, and remote control subsystems that are capable of streaming timestamped quadrature (I/Q) data straight to storage.
