Abstract :
At this time the rocket design is being developed, namely a rocket with an
EDF (Electric Ducted Fan) propulsion system which is an unmanned rocket that
is controlled from a runway used for certain missions. One of the important
components in a rocket payload (PayLoad) is a temperature and humidity sensor
and a compass-type sensor. The function of temperature and humidity sensors as
well as sensors in the form of a compass are part of the components that are very
influential in rocket design, so it is necessary to do half-duplex communication for
rocket research and ground segments. The purpose of this study is to determine
the results of data communication, determine the characteristics of the workings
of the half-duplex communication system, and determine the maximum distance
between the rocket and the ground system.
In this study, a simulation of the communication system between the
ground segment and the rocket is made. This system is designed so that the
ground segment sends commands to the rocket to send sensor data to the ground
segmnet. The use of sensors is replaced by using a potentiometer because the
system is a simulation. With this system, user can monitor the position of the
rocket from sensor readings on the rocket in real time
The results showed that the system's ability to make communication
based on the half duplex communication protocol, the ability of the rocket to read
and transmit sensor data twice per second, and the ability of the ground segment
to give orders to the rocket to start sending sensor data to the ground segment.
