Software Development for the Grape Personal Space Weather Station v2
The HamSCI Grape 2 Receiver is a high frequency (HF) Doppler radio receiver designed primarily for use by citizen scientists. It is capable of monitoring HF Doppler shift on three simultaneous channels of signals received from standards stations WWV (Colorado), WWVH (Hawaii), and CHU (Ottawa). Approximately 30 Grape 2 receivers have been distributed across the continental United States and Canada, augmenting an existing network of approximately 50 Grape 1 receivers. Observations from these receivers are used to study a wide variety of ionospheric phenomena, including impacts of solar flares, geomagnetic storms, traveling ionospheric disturbances, and other forms of short-period ionospheric variability. This poster showcases several software aspects of the Grape Personal Space Weather Station v2. G2console is a lightweight terminal-based interface that communicates with the data collection system and GPS module, providing users with useful real-time information such as software versions, amplitude, frequency, GPS, and magnetometer metrics for viewing and diagnostics. GrapeSpectrogram is a data processing script that generates Dopplergrams, demonstrating the Doppler shifts and aiding developers in validating the system's operation. The generated data is stored efficiently in DigitalRF, a format specifically designed for archiving and managing RF data. The DigitalRF artifacts are then uploaded to a central database at the University of Alabama for public access.
