With the salty demise of the Ava1 flight hardware I have a choice. Make another (I have spare components and one spare PCB) or re-design it. The board had a number of flaws and was quite large. I’d planned to re-design it after the first flight anyway. My criteria was smaller, more features and more robust. The Inventek ISM GPS is a bit long in the tooth and I really don’t want to use another antenna patch like the one that failed on Ava1.
Enter the uBLOX 6 NEO and the Sarantel Antenna :
The Sarantel is a helical antenna which is compact and robust and importantly doesn’t move. The uBlox 6 NEO is a brand new very high performance GPS chip. I’ve designed a break board in Eagle for the uBLOX 6 Neo which is on my Github here http://www.github.com/upuaut Look for uBlox_NEO-6Q_Breakout. I have a few spare boards (got 18 made in total) so if you want one give me a shout on #highaltitude.
