I ran your GPS-1 sensor and GPS data through a post-processing program
I am working on.  Here's the good parts.

Launch Site and position

t=2305s{10.18V,180.40mA,62.00F}<36.51,-120.07,166.01ft> dt=1.00 dv=0.00 d=496.23ft,b=175º [S5E-LS],<36.51,-120.07,166.01 feet> d=0.00ft,b=0º [N360W-REL][21 Mar 15 23:07:13]


Launch and boost, 16 seconds and we are > 200 fps so we get GPS lock-out, here we recover, 227 feet/second and 12K'
