Week 1 02/18/2025
Summary
Enhanced recording scripts, updated location/time settings, and automated data acquisition and scheduling. Explored alternative SDR solutions.
Accomplishments
Recording Scripts: - Auto-creation of directories, termination of existing rtl_fm processes, absolute path usage, and detailed logging.
Script Updates: - Updated new.py with corrected coordinates, timezone (EST), noise command, and PNG management.
SDR Integration: - Connected SDR to gpredict, adjusted NOAA15 frequency, and tested gqrx as an alternative.
Data Pipeline: - Created “Emir” folder, developed n2yo.py for data scraping, used filter.py to refine data, scheduled recordings with schedule.py , and automated the workflow with runall.py .
To Do
-Test and debug record.py and automation loop. -Resolve remaining SDR and scheduling issues. -Fine-tune data processing and logging.
Week 2 02/25/2025
Summary
This week, we focused on refining the satellite image processing pipeline, debugging existing scripts, and optimizing the scheduling system. We also improved the prediction and recording workflows to enhance data acquisition reliability.
Accomplishments
Recording & Processing: -Successfully tested and confirmed that record_passes generates valid WAV files. -Implemented and configured the predict software for our system, ensuring seamless execution. -Updated TLE files using schedule_all.sh and calculated satellite pass predictions. -Filtered valid satellite passes with an elevation range of 19 to 91 degrees using schedule_satellite.sh. -Successfully generated a WAV file with receive_and_process_satellite and processed it into an image.
Script Debugging & Enhancements: -Attempted to generate WAV files using the ephem library to predict satellite movement, but encountered issues and decided to halt further development. -Identified and resolved an issue in the script where wxotimg was not running in quiet mode, preventing popup interruptions. -Tested new WAV files and attempted fixes for mcir and hcvt, which were producing grayscale images instead of colored ones. -Confirmed that thermal and sea images generated correctly.
To Do
-Investigate and resolve why mcir and hcvt images are in grayscale instead of their intended color formats. -Debug the missing map overlay in the generated images. -Continue optimizing the scheduling and recording processes for improved efficiency.
