1. 1 ARMADILLO – SHOT II The University of Texas at Austin Travis Imken Shaina Johl Christopher McBryde Travis Sanders June 29, 2012 Boulder, CO

2. Mission Overview Verify that the CDH runs, uses SD card, manages subsystems, records data Validate COM uplinking/downlinking Confirm that EPS provides steady 3.3V, 5V lines Gather FOTON GPS data to compare to previous experiments. Pressure/temp sensor integrated 2 The SHOT II payload contains identical or very similar hardware to ARMADILLO flight design. The CDH, EPS, and GPS subsystems and NVS camera same as flight The COM is half-duplex version of flight. NVS lens is similar.

3. Design EPS system from ARMADILLO running multiple subsystems. Data collected in flight autonomously and recorded to SD card. Payload pinged via uplink to downlink dummy voltage data and magnetometer measurements. 3

8. Test Data 8 Discharging Curve with Electronic Load: constant current of 1.0A on 5V bus

9. Expected Results Recorded results from the magnetometer at 10 Hz Images from the camera every 30 seconds COM beacon roughly every 45 to 50 seconds Downlink data and turn on/turn off beacon upon ground command GPS readings from FOTON for post-launch analysis 9 Pressure data to correlate with GPS altitude (and temperature)
