mile carrying the Operation: Epic Beep payload mile carrying the Operation: Epic Beep payload package. At lift off, the rocket’s payload will begin package. At lift off, the rocket’s payload will begin emitting a series of high volume “beeps” at one-emitting a series of high volume “beeps” at one-third-second intervals. These beeps will cease at third-second intervals. These beeps will cease at apogee. By recording and analyzing the beeps, we apogee. By recording and analyzing the beeps, we will be able to determine velocity, acceleration, and will be able to determine velocity, acceleration, and altitude of the rocket throughout the duration of its altitude of the rocket throughout the duration of its flight. This data will be compared toflight. This data will be compared tocomputer simulation data and onboardcomputer simulation data and onboardtelemetry to determine the accuracy oftelemetry to determine the accuracy ofour measurements. our measurements.
