Missions

Primary Mission: Passive Electronic Recovery Reporter - Capsule (PERR-C)

PERR-C is the main payload for our vehicle this year as outlined by the requirements for NASA ULSI 2025. The goal for PERR-C is to safely land 4 STEMnauts and transmit flight and landing zone information from a Student Research and Designed (SRAD) flight computer over 2m (144mhz) radio. The flight computer being developed for this, the Payload Electronics Package (PEP), is a new design for UML Rocketry, expanding the sensor package and capabilities from previous computers the club has developed.

Secondary Payload: Altitude Control System (ACS)

To complete the second part of our mission, delivering our Primary payload to a specific target altitude, we will be developing a system to modify our altitude in flight so that we can accurately hit that goal. This system will utilize the development that is happening with PERR-C by using the same electronic design for the electronics controlling the ACS.
