    Flight Payload Hardware and Software

    Some of you may have thought that the guys in the white coats had taken me away. Nope. I've spent most of the summer updating my Flight Data Recorder with new options.Flight Payload Hardware and Software-fdr-iridium-gps-runcam.jpg

    The orange box is a RunCam camera. The small board with the patch antenna is a GPS. The larger board with a patch antenna is an Iridium Modem.

    Attached to the Iridium Modem is a small board that supplies power. It connects via a ribbon to a "shield" which contains a Sparkfun Pro Micro system.

    The Flight Data Recorder also has a Pro Micro which is in charge.

    Under software control, I can take still pictures or videos. The GPS (or GNSS) receiver feeds me time, lattitude, longitude, and alititude. Those were the easy bits.

    The Iridium Modem took most of my time. It permits me to pass data between the Flight Data Recorder and a similar modem anywhere in the world via the Iridium Satellite System. To do this, assuming there are no faults, takes just a few lines of code. To handle the many fault cases and decide what to do about them took 16,000 bytes of code. This is why I needed to add a second processor.

    Some of this system will be flown up to around 100,000 feet this fall. The rest will go up in the spring.

    My brain hurts...

    Ok, so I went through a bunch of your previous posts, looking for a clue what you are going to put this device into. From the title I have to assume it is planned for a flying device since it has something to do with a "flight payload".

    100,000 feet is no small task, you can't leave us hanging here, what is the rest of the story?

    Payload ties to a weather balloon that starts out about 15’ in diameter. When it gets to about 50’, it pops. The balloon is managed by ANSR (Arizona Near Space Research). A typical flight lasts 90 minutes and we drive about 100 miles to retrieve it. The record is 2200 miles (didn’t go after that one). The minimum distance record is 20’. It went up, circled, and came down.

    The program is for college students and is sponsored by NASA. The program, Arizona Space Grant Consortium, is “hands on” and has been very effective at drawing students into engineering. It is also great fun to teach. Been doing it for 10 years now.
