PROMPT - Project for Recording, Observing, and Measuring Parachute Tube
The PROMPT is a remote sensor daughterboard that will be placed at the base of the parachute bay, to record metrics regarding the operation of the parachutes. The data from this module will be sent back to the main sensor board over RS485. Data will be measured at 100Hz from right after launch to 30 seconds after parachutes deploy. The data measured includes:
