The one final issue with my design, the intermittent operation of the GPS has been fixed. Looked like a dry joint on the VCC for the antenna. After a repair job (see picture below) the GPS started spewing forth location information as intended. Additionally I did my first untethered battery powered test which worked perfectly. Its worth noting at this point even if you are using one of Inventek’s active patch antennas you must still power pin1. I know I’m not the only person to make this mistake, Inventek recommend an inductor/capacitor filter/protection on this pin as well so I’ve included this in my design (note the surface mount inductor on breadboard!)
