Abstract :
Payload or rocket payload is one of the electronic objects that is currently
being developed through a competition built by Dikti and LAPAN, namely
Komurindo. The payload is the substance that is carried inside the rocket. In the
Indonesian Rocket Cargo Competition, each contested rocket payload uses
sensors to measure meteorological parameters and rocket motion behavior. One
of the most important sensors in a rocket is the accelerometer sensor, because the
sensor can detect the flight attitude of the rocket. This study aims to determine the
value of the pitch and roll angle on the MPU-6050 accelerometer sensor which is
used in the payload of the rocket and then compared with the theoretical
calculation of the pitch and roll formula.
The MPU-6050 accelerometer sensor used in the rocket payload uses the
KYL-1020 transmission communication method. The MPU-6050 accelerometer
sensor functions to read the x,y, and z acceleration values on the rocket payload,
then the x,y, and z acceleration data values will be accessed by the
microcontroller and the processing results will be sent to the ground segment to
be displayed on visual studio using KYL 1020. Sensor data displayed in visual
studio will be calculated using the pitch and roll formula to get the pitch and roll
values. Then it will be compared with the experimental angle that has been
determined to determine the accuracy of the accelerometer sensor.
The results of this study indicate that the pitch and roll angle determinants
on the rocket payload based on the MPU-6050 accelerometer sensor using KYL-
1020 can work well and according to the function of each component. The
accelerometer sensor will read every x, y, and z acceleration value data that is
processed by the microcontroller to be sent to the ground station using KYL-1020
which can be sent within 350 meters to be displayed in visual studio. The
displayed acceleration data value is calculated in the pitch and roll formula to
determine the pitch and roll angle of the payload. From the actual comparison of
the pitch and roll angles according to the results of the formula calculations with
the error rate at the pitch angle not more than 3% and the roll angle not more
than 1%
