Hi! Lots of updates! Executive summary: we're go for launch 7/20.
### Last night. Gavin, Kenny and I worked on the avionics last night. As of this morning, the GPS system is now fully mounted and we even have confirmation that the COTS GPS system gets lock through the cylindrical patch antennas, low noise amplifier, and splitter. This is very good news: now we'll integrate in Jenner's GPS. Also, we stuffed the raspberry pi carrier boards and mounted it to the avionics systems. As of Tuesday night, we'll be officially done with the avionics system, and be able to button it up for flight / testing / whatever is next. ### Today's integration day Integration day at Dave's house went "just OK" today. Kenny, Dave, Gavin, Glenn, Bart, Erin, John and Nathan all helped out setting up the launch tower computer, launch control, and all of the interlocking systems. We had some problems with the Beagleboard in the Launch Tower Computer which ate some of the day up. We don't think it's RF issues, we think that the phidgets web service is doing bad things to the board. It could also possibly be heat - it was acting up during the heat of the day, and magically fixed itself when it was cooler. We'll test the board at elevated temperatures to see if that makes it fail. Once those issues resolved themselves, we launch the rocket with no problems twice. THAT part went swimmingly well. We're threatening the LTC with either dry ice packs or replacement by a raspberry pi - we'll see after further testing. ### Next up - Button up the avionics system for flight Tuesday night. - Finish the umbilical disconnect system ASAP. - Another drop test, this time with the full avionics system running. Maybe on Friday? - A full communication test, to prove the full working system out in the field. More Tuesday!
