Abstract
For more than a year in the IDeTIC there have been students working with UAVs. By now two ways of communication are used for sending commands to the autopilot - by hardware connection to the APM which is not possible to be used while the ArduCoper is flying, or by 433 MHz radio frequencies which could be used while the copter is in motion but does not provide enough quality of the signal when the copter is far away from the ground control station (GCS). The solution of providing a reliable communication that can be used independent on the distance is to set the connection between the APM and the ground station via the satellite network, which will give the opportunity to send and receive commands on unlimited distances.
Arduino is an open-source physical computing platform based on a simple microcontroller board and a development environment for writing software for the board. It will be connected to an Iridium single board transceiver allowing short-burst data (SBD) connectivity to the Iridium satellite network. An ArduCoptetr, which is an open source multicopter UAV based on the Arduino platform, will also be connected to the Iridium and Arduino.
The objective of the current project is to implement a bidirectional communication system for the ArduCopter model to send flight commands and receive telemetry – altitude, longitude, latitude. The solution will use Iridium transceiver and Ardupilot system. As a backup decision for receiving the coordinates of the copter, a GPS could be attached.
