At time: 4425 seconds (73 minutes, 1:13) Voltage jumps from 0.58 to 2.74 volts. Time starts to go backward in the log, now to 4216 - glitch! This glitches the SD-Card data, as we lose part of the GPS prefix for: $PRFSA, tmsecs, only get: 2.74 V 310 mA 0 mA 0.01 V 0.01 V 0.02 V 0 V 165.1 F 74 C*7F 5241 seconds Voltage drops to 1.62 volts Something apparently has shorted onboard the vehicle. We get a corrupted line in sensors.prn which reads: F 33.5 C*75 the next time-stamp is 6540 seconds (1299 seconds later or 21 minutes later) Run time is 7016 - 6540 = 807 seconds or 13 minutes. After time 7016 seconds, voltage is at 1.59v, drops to 0 volts and then time is 6209 seconds(ends at 8774 or 2565 seconds, 60 minutes) Battery is not dead, but 10.4 volts when found. Inspection of the board shows pins J1 HDR 4, Pin 1 (3.3VCC bent) and shorting the power supply. This jumper should be removed in all production boards. This explains the failure at time 5241 seconds or 1hr, 27 minutes Inspection of the GPS log file shows the Epoch (first boot/lock) at: Order Latitude Longitude Elevation Date Created Distance from Start Distance to Next Bearing Speed Time 1 36.48058 -120.12655 0.000 7/21/2012 3:28:29 PM 0.000 0.039 283.5 138.8 1.0 Launch occurs at: Order Latitude Longitude Elevation Date Distance from Start Distance to Next Bearing Speed (mph) Time 1188 36.48121 -120.12654 184.055 7/21/2012 3:48:16 PM 0.535 0.017 267.2 61.6 1.0 1189 36.48120 -120.12685 184.055 7/21/2012 3:48:17 PM 0.552 0.046 269.3 165.0 1.0 1190 36.48119 -120.12766 222.441 7/21/2012 3:48:18 PM 0.598 0.061 273.4 218.8 1.0 1191 36.48124 -120.12863 366.798 7/21/2012 3:48:19 PM 0.659 0.066 50.6 119.3 2.0 1192 36.48153 -120.12819 673.885 7/21/2012 3:48:21 PM 0.725 0.518 85.2 1864.4 1.0 1193 36.48159 -120.12730 3395.669 7/21/2012 3:48:22 PM 1.243 0.279 38.7 1004.2 1.0 Apogee happens: 1239 36.48630 -120.12695 9049.869 7/21/2012 3:49:08 PM 2.742 0.004 0.6 13.9 1.0 1240 36.48635 -120.12695 9049.869 7/21/2012 3:49:09 PM 2.746 0.004 6.6 15.9 1.0 1241 36.48642 -120.12694 9049.869 7/21/2012 3:49:10 PM 2.751 0.013 19.3 45.6 1.0 1242 36.48649 -120.12691 8988.845 7/21/2012 3:49:11 PM 2.763 0.007 19.4 26.8 1.0 4443 36.48058 -120.12640 190.945 7/21/2012 4:42:33 PM 9.108 1.063 350.5 -0.3 -12968.0 At 4:55PM
