Post-Launch Analysis of Missouri S&T's Satellite Team's SHOT II Performance and Results

The Missouri S&T Satellite Team's SHOT II mission aimed to enable communication between two payloads in space. Each payload was designed to transmit and receive character strings, with successful ground-range tests achieving communication at 155 m. However, a critical failure occurred two minutes before launch, likely due to a receiver malfunction. Data was collected before launch, revealing 31 characters received and 1030 characters transmitted over 2.8 hours. Post-recovery tests showed successful communication, indicating potential for further investigation into failure modes.

  2. Expected Results • The two payloads should be able to communicate throughout the mission • The transmitting box sat will send a string of characters in a repeating pattern to the receiving box sat • The transmitting box will record the number of characters sent and the receiving box will store the actual characters for later comparison • A ground range test was performed and the boxes functioned to a distance of 155 m

  3. Results • Unfortunately, the team experienced a failure approximately 2 minutes before launch • It was determined that this was due to a receiver malfunction or unforeseen interference • Data received for approximately five minutes (31 characters) prior to launch • Data transmitted for 2.8 hours (1030 characters)

  4. Conclusions and Actions • When the payloads were recovered, they were turned off before being reopened • This did not allow for clear determination of the state of the receiver balloonsat • The two payloads were tested after recovery and communicated successfully for an extended duration • Tried several configurations to determine failure mode
