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
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)
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
