Implementation Of Error Checking In Data Security In Ground Control Station And UAV Communications

The Indonesian Flying Robot Contest (IFRC) is a very prestigious unmanned aircraft competition in Indonesia organized by the Ministry of Research, Technology and Higher Education of the Republic of Indonesia through the National Achievement Center which is used for all universities in Indonesia. in this competition, participants are required to make an unmanned aircraft with a control system as a control aircraft and make a Ground Control Station (GCS) where the vehicle must be able to fly and carry out missions in accordance with the regulations stated in the competition technical guidelines.In this research is specialized in securing data when sending to the Ground Control Station. making Ground Control Station using Node.js in designing the front end and back end design and the value that will be sent by researchers using a simple design tool using Arduino Mega as a data transmission controller, the sensor used uses Mpu 6050 Inertial Measurement Unit (IMU) and Global Positioning System (GPS) Neo 8m, and the telemetry used is NRF24l01. Based on the test results by sending 11 sensor data using checksum, it is found that the amount of sensor data entering the Ground Control Station is still safe and can minimize damage to data packets and using Cyclic Redudancy Check (CRC) as a checksum, the integrity of the data received is maintained quite well because the Cyclic Redudancy Check (CRC) algorithm is able to discard incomplete / damaged data.
