There are various frequencies used in the data link system. The frequencies that are used are based on UAV brand as well as functionality of the UAV. For example, the DJI systems use 2.4Ghz for UAV control and 5Ghz for video transmission. This setup will give the user approximately 4 miles of range. However, if using 900Mhz for UAV control and 1.3Ghz for video, a distance of 20+ miles can be achieved.

Many other countries feature a red and white striped flag which includes a design or the addition of blue stripes. The flag of the United States is a prime example of a predominantly red and white striped flag that features a blue corner with white stars. Other flags which feature red and white stripes include Liberia and Malaysia.

This section introduces the subsystem at the heart of any UAS, the UAV. The UAV can either be a fixed-wing, rotary wing, flapping wing, or lighter-than-air. Each category has specific pros and cons over their counterparts.

A “drone” or Unmanned Aerial Vehicle (UAV) is one of multiple components in an Unmanned Aerial System (UAS). “Drone” according to Webster’s Dictionary is a “pilotless airplane controlled by radio signals”. The term “drone” was adapted during World War II, where UAVs were used as target practice for fighters and anti aircraft guns. Today the UAV developer and user community does not use the term drone except for vehicles that have limited flexibility for accomplishing advanced missions and fly in an indifferent manner, such as a target drone used for combat training. This article is meant to provide a basic understanding of the Unmanned Aerial System (UAS) platform and its components.

Austria is another prominent country to feature a flag with only red and white stripes. This flag is made of three stripes, with two red stripes bounding a middle white stripe. Singapore's flag is very similar to Indonesia's, featuring a red stripe over a white stripe. However, a white symbol featuring a crescent moon and stars is displayed in the upper left corner of the red stripe.

The type and size of the payload generally sets the restriction on the type and size of the UAV to be used for the task. Various payload types are capable of being carried by a UAV:

Lighter-than-air UAVs are aircraft such as blimps and balloons. These vehicles benefit from quiet operation and endurance. With their long endurance flight capability these vehicles can be used for surveillance and aerial photography. However, due to their lack of maneuverability these systems are usually tethered. The tether allows the user to maintain control and to keep the UAV from drifting due to winds. In some systems the tether can also act as a communication system to download and upload information from the vehicle.

Still, other red and white flag variations exist, with some countries featuring a crest or symbol within the red and white stripes. Lebanon, Gibraltar, and French Polynesia are great examples of flags that are mostly red and white striped but have the addition of a symbolic crest.

The ornithopter or “flapping wing” utilizes bird flying mechanics as the power source of the UAV. This technology has been used by the military to develop a small “bird-like” UAV capable of surveillance. However, there are a few downsides to this technology. One downfall is the lack of flight time due to the extreme power requirements needed for the flapping mechanism. Another downfall is the lack of maneuverability. However, as this technology advances the ornithopter UAV may become increasingly more popular to the public.

Unmanned Aerial Vehicles (UAVs) can be used in various applications. The 4 components of UAS mentioned above allow UAV's to be used for good, but they also open up an avenue for UAV's to be used for harm. Depending on the user, these applications can be beneficial or cause harm to the community. To ensure UAV's are safely implemented into today’s technology driven communities it is necessary to inform individuals, commercial entities, and government personnel about this rapidly growing industry.

The Data Link portion of the UAS platform also happens to be the most vulnerable in detection and cyber-attacks. Many UAV detection systems use the data link footprint as their main method of UAV detection.

Fixed wing UAVs can carry various payloads and data-link equipment. The fixed-wing has the longest range over any of the other categories. However, the downside to this platform is the requirement for a runway during landing or takeoff. This issue is currently being resolved by UAV manufacturers by developing a fixed wing aircraft with the ability to take off vertically and transition to horizontal flight. This type of fixed-wing aircraft has Vertical Takeoff and Landing (VTOL) technology.

Ground Control stations come in various complexities and sizes. These platforms can range from backpack sized to permanent buildings

Data link uses a radio-frequency (RF) transmission to transmit and receive information to and from the UAV. These transmissions can include location, remaining flight time, distance and location to target, distance to the pilot, location of the pilot, payload information, airspeed, altitude, and many other parameters. This data link can also transmit live video from the UAV back to the GCS so the pilot and ground crew can observe what the UAV camera is seeing.

Another flag variation which includes red and white stripes features a blue triangle bounded to the left of the flag. The point of the triangle then intersects the area between the red and white stripes. This popular flag design is featured on the former flag for Czechoslovakia and the current flag for the Czech Republic. Puerto Rico has a flag design that is similar to this variation.

Flags carry plenty of symbolism and history, and often, the colors used to decorate a flag hold special meaning. According to tradition, white usually represents innocence or purity. The color red can symbolize courage, but it has recently come to represent the blood shed by soldiers and citizens fighting for independence. Red can symbolize boldness or power, particularly popular for countries who have successfully revolted, starting a newly independent country.

The ground control station is the nervous system of the operation. The GCS will control the launch, flight, and recovery of the UAV. It also processes the data from the internal and external sensors of the payload. To perform this task the GCS incorporates the following subsystems:

The most popular rotorcraft platform is the quadcopter. This provides for a stable and simple to operate UAV that can carry a wide variety of payloads, landing and taking off in a small space, and being harder to detect than many of the other UAV configurations due to small size and quiet rotors.

Many countries have adopted a flag that features red and white stripes. The stripes can run horizontally or vertically, displaying a bold and prominent bicolor flag. Typically, horizontal stripes are more common. Poland, Monaco, and Indonesia have very similar flags. Each flag with red and white stripes features only one stripe of each color. Poland has a white stripe on top of a red stripe, while Monaco and Indonesia feature a red stripe on top of a white stripe. Indonesia and Monaco's flags only differ in the shade of red used. Monaco has a lighter red, while Indonesia's flag features a deeper red.

There are two types of rotorcraft. One being a helicopter, consisting of a single rotor system. Another type being a multirotor. A multirotor can have up to 8 rotors on the platform. The added motors provide greater stability, redundancy, and greater lifting capacity.
