Mission Overview:
- Verify the data link between the payload and
ground station in a highly dynamic environment
-Test all interfaces remotely (LVDS, UART, SPI
etc.) and store payload data and telemetry beacons
on-board
- No RF communications at this time
- Analyze data post-flight using GSE software
- Look for bugs in flight software or electrical
interfaces that cause a system reset or missed
beacons

Expected Results:
- Confirm payload data and beacon timing with the
system clock information stored in each packet
- Payload data increments with each packet sent, no
packets missed
- Track battery voltage and current over flight:
1) No large fluctuations in current
2) <20% battery depth-of-discharge
- Produce time-series plots with GSE software

Actual Results and Analysis:
- Flight went as expected: Collected internal and external
temperatures, battery voltage and current, and dummy
science data from payload
- System clock indicated that data was collected for the
duration of the flight
- Average beacon cadence matched expected values in
payload and CDH (<5 min error compared to flight time)
- Internal temperature remained above 0˚C (External
reached nearly -40˚C)
- Battery depth of discharge was less than 7%
- Battery DOD matches expected (<20%)
- Structure performed flawlessly

Preliminary Failure Analysis:
- Payload data analysis…
- Difficulty loading recorded data into GSE computer,
suspect a faulty virtual comm port?
10
Conclusions and Actions:
- Primary mission goals were achieved
- Adjustments need to be made to GSE software
to improve data import capabilities
