Extensible SSEL Beacon Parser for HAM Operators Andrew Seel Summer 2013 REU Project August 2, 2013 FIREBIRD Science
Requirements ● Monitor serial stream ● Identify, collect, and validate SSEL packets ● Send validated SSEL packets to SSEL ● Select mission of interest (e.g. FIREBIRD, EPISIM) ● Display and/or plot variables of user interest ● Distributable as a single executable (Not Open Source) FIREBIRD Science
Original Flowchart FIREBIRD Science
Programming Language ● Python 2.7 ● Tkinter Cross-platform GUI toolkit – ● Matplotlib and Numpy Graphing – ● PySerial Serial Communications – ● PyInstaller 'Compiles' python files into a single standalone file – FIREBIRD Science
Current Progress ● Barebones GUI ● Serial Port selection Attempts to autodetect ports on the system – Allows for user to type in port name if correct port isn't detected – ● Detects FIREBIRD packets Unstuffs, Checks CRC, Checks spacecraft ID fields – ● Parses FIREBIRD packets into Python Dictionaries {“BEACON_SYSTEM_TIME_YEAR”: 2013, “BEACON_SYSTEM_TIME_MONTH”: 8, etc} – ● Graphs user selected variable from a series of packets Updates when a new packet is received or variable selection changes – FIREBIRD Science
Current Classes ● APP FBGUI – FULAYOUT ● – graphWithSelector UNSTUFFER ● – UN_ENUMS beaconParse ● beaconConvert ● ● SERIALMONITOR FIREBIRD Science

Screenshots FIREBIRD Science
Screenshot: with fake data FIREBIRD Science
To Do ● Verify serial data parsing with data from the Firebird engineering unit ● List the remaining variables in the bottom right quadrant Use values from either first packet or packet currently highlighted in the packetLog – ● Export packets to SSEL ● Write GUI_CLASSes for other missions ● General GUI cleanup FIREBIRD Science
