Using unusual communication methods can be effective to increase fighting power. For preventing the communication from eavesdropping, using the DSSS (Direct Sequence Spread Spectrum) method is one of the main solutions. In this method, because of hiding the signal under the noise level, communication identifying, eavesdropping, and jamming is very complicated. This system is a radio communication link between RPV/UAV and ground station so that transmit control commands to the RPV/UAV and receive telemetric information from it using the method.
