Design of Data Acquisition System for Position and Attitude Quadcopter

Quadcopter requires monitoring to determine the position and attitude of the object when flying. Attitude consists of roll, pitch, and yaw angles. In quadcopter monitoring is difficult when the object is flying away and outside the operator's viewing range. Monitoring requires a monitoring system to monitor objects further. One way that can be used to determine the position and motion of a quadcopter is by combining GPS technology and Inertial Sensor. This study discusses data acquisition to monitor the position, attitude, and value of reading the sulfur gas sensor in the quadcopter by combining GPS and Inertial Sensor. The communication module used is 433 MHz radio frequency with STM32F103 and the main microcontroller using STM32F4DISCOVERY. Data about accepted objects is then displayed through Visual C # in real time. Testing of latitude and longitude is done by tracking the path of the object, while testing roll, pitch, and yaw angles is done by placing the object in accordance with the reference angle.
