Drone Transmitter: Function, How It Work, and Another Beginner Guide

In general, a transmitter is an electronic device board that functions to transmit and receive data in 2-way telecommunications activities via radio waves. Then, what is the definition of a drone transmitter?

A drone transmitter is used to control a drone via radio signals in a more specific context. This control activity can occur due to the exchange of data between the transmitter and receiver. The transmitter receives commands/data from the receiver, which is directly connected to the flight controller inside the drone.

Typically, a radio control system consists of two essential elements, namely a transmitter and a receiver. A transmitter is an object held in hand. At the same time, a receiver is an object inside the drone.

The drone transmitter and receiver are inseparable, like a husband and wife on their honeymoon. If one is missing, the other will disfunction.

In practice, when the drone is too far from the pilot, the drone transmitter cannot be used as a controller anymore.

Drone transmitters go by many names. There are flight controllers, remote control drones, drone controllers, and radio transmitters.

How Does Drone Transmitter Work?

The drone controller works by sending radio signals to the receiver inside the drone. The receiver will tell the flight controller inside the drone what to do.

So indeed, the benefit of drone transmitters is that they give pilots the ability to tell the UAVs what action to take.

Radio signals are sent from a radio transmitter, which is on the drone controller, and received by a receiver inside the drone. For this reason, drone controllers are often  mentioned as drone radio controllers or drone radio transmitters.

Type of Drone Transmitter

In some cases, the drone’s remote controller does not have a screen. Therefore, you can add a smartphone or tablet as a screen to get an FPV (First Person View) flight perspective.

Another thing to consider is when buying a drone transmitter, make sure you have determined what kind of mode suits the pilot’s flight style. To determine what kind of controller is suitable for the pilot.

This mode will determine how and how the drone moves. There are four kinds of drone transmitter modes. However, the popular ones available in the market are only two modes—both modes as the default mode in various types of flight controllers.

As explained above, the drone’s transmitter will communicate with the receiver if the two are bonding. To be able to bind the two, specific actions and processes are needed.

In some receivers and transmitters, the pairing actions and processes may differ. However, on most devices, this pairing process follows the same pattern. Therefore, referring to the user manual is the best way of knowing how to do proper pairing.

It is also essential to know that one transmitter can be paired to several different receivers. Meanwhile, one receiver can only be paired to one transmitter.

Drone Transmitter Frequency

Drone transmitters typically use radio frequencies of 27MHz, 72MHz, 433MHz, 900MHz, 1.3GHz, and 2.4Ghz. Generally, the 433Mhz, 900Mhz, and 1.3GHz bands are being used to control drones and RC devices.

2.4GHz is the type of frequency that is currently popular. The technology in this new frequency is more promising because it can provide a feature called frequency hopping.

This feature allows the activity to manage the frequency transmission of several users at the same time. The 2.4GHz antenna is also compact. This attraction makes the 2.4GHz frequency quite popular with pilots.

However, pilots and drones still need some other types of connections. The following are some of the kinds of signals that are often found and utilized in drone flights:

  1. GPS gives pilots access to precise location and position. The GPS connection also enhances several features in the drone.
  2. Wi-Fi provides the capability for drones and pilots to exchange data within a specific control radius.
  3. Bluetooth is an alternative to Wi-Fi as a data exchange connection.

When choosing a drone transmitter and receiver, make sure that they are both snug and compatible. The compatible context here is not only for the need to exchange data via radio. However, it is also suitable for the needs of pilots and drone capabilities.
