With drone sales expected grow exponentially in the near future, and an increasing number and severity of drone incidents occurring daily, DroneShield launched DroneGun to respond to nefarious use of consumer and commercial drones and the resulting need for effective countermeasures to drone intrusions. DroneShield aims to help public and private sector customers, where allowed by law, take proactive measures against airborne threats to safety, security, and privacy.
How Do Drone Jammers Work?
Jammers are designed to disrupt a drone by blasting electromagnetic noise at radio frequencies that drones operate and transmit video at, and at a power level high enough to drown out any effective communication between the drone and its pilot. Generally, this is either 2.4Ghz or 5.8Ghz ("RF-jamming"), which are "non-assigned" public frequencies meaning that drone jammers will not interfere with manned aircraft, cell phones, public broadcasts, or other dedicated radio bands. In addition to RF-jamming, where legal for the customer (which depending on the jurisdiction, may include military, law enforcement, first responders and private users), GPS jamming may also be utilized, as a large number of drones rely on GPS either to balance against wind, or to go between pre-determined way-points.
When a drone is hit with a jammer's signal, the drone usually returns back to its origin point (unless GPS is also jammed), giving the jammer user the option to track the drone back to the pilot. Sometimes the drones might even perform a vertical descent and land on the spot intact, which offers the option of performing a forensic investigation. Landing on the spot is also the general response from drones when both RF and GPS are jammed at the same time.
Jammers can be effective against drones over several kilometres away. Generally, jammers operate on a ratio of distance between a drone and the jammer compared to the drone with its pilot. The further away the drone is from the pilot and closer to the jammer, the better. A typical effective jammer direction is a cone of about 15-30 degrees, projecting forward from the gun (this is also influenced by the RF band and the power of the jammer).
Why Are Jammers A Safer Choice Than Other Countermeasures?
Jammers are effective against drones without destroying the drones and evidence. Other options often result in damage or destruction to the drone, which can destroy evidence and also result in private property destruction charges.
Another consideration is if a drone is carrying a bomb or another dangerous item. Using a jammer is likely the safest course of action, because the jammer will usually cause the drone to return to its point of origin. This is much safer than shooting down a drone equipped with a bomb, which could lead to detonation of the bomb, injury, or even death.
Are Drone Jammers Legal?
While jammers are generally restricted for use in many countries except by the military, police, and first responders depending on the laws, non-GPS jammers are legal in a number of countries. It is important to look into the laws and regulations of the country and state that you are in to determine whether the use of a drone jammer is legal before operating one. DroneGun has not been authorized as required by the United States Federal Communications Commission ("FCC"). This device is not, and may not be, offered for sale or lease, or sold or leased, in the United States, other than to the United States government and its agencies, until such authorization is obtained. The use of DroneGun in the United States by other persons or entities, including state or local government agencies, is prohibited by federal law. Laws limiting the availability of DroneGun to certain types of users may apply in other jurisdictions, and any sales will be conducted only in compliance with the applicable laws.
Why Are Drone Jammers Needed?
Consumer and commercial drones come a dizzying array of shape, size, characteristics, features, and prices from $30 consumer drones to $30,000 military-grade weaponised drones. That means that drones can also be employed for a huge range of illegal uses including:
- Carrying bombs and other terrorist threats
- Use as biological weapon
- Illegal surveillance
- Drone swarms overwhelming a facility
- Interfere with emergency responders
- Interfere with manned aircraft or airports
- Smuggling contraband into prisons or across borders
- Hacking into sources such as datacentres
Security needs have changed, and traditional security methods are not effective against attacks by air with drones. In the last two months alone, terroristic drone incidents included:
- An ISIS drone rigged with explosives killed two peshmerga fighters and wounded two French soldiers*
- ISIS drones released hand grenades against US-backed forces* and
- ISIS employing drones for battlefield surveillance*
This has prompted Air Force Secretary Deborah Lee James to state "A top priority for me at the moment is this emerging danger that we're seeing in the Middle East in respect to unmanned aerial systems - these cheap, buy-them-over-the-internet, small drones and if explosives are placed on them, as we've seen a handful of times now in Syria and Iraq, they can do damage," as reported by Defensetech.org on October 31, 2016.
Other incidents over the recent months have included:
- Multiple drone incidents at Heathrow Airport*
- Dubai Airport drone incursions* and German authorities recording over 40 incidents of drones near passenger planes*
- Drones dropping weapons, escape kits, drugs and mobile phones into HMP Hewell prison* assisting prisoner escape at HMP Pentonville prison* and smuggling drugs into Birmingham prison*
- Drones used by fans to get illegal spoilers for upcoming Game of Thrones series*
- Drone security scare at Taj Mahal*
- Drones impending fire fighters in Kentucky*
- Drones used to harass nesting eagles in Vancouver* and crashing into Otago albatross colony*
- Drones used by paparazzi for celebrities' privacy invasion*
- Drones illegally flying over Hong Kong Formula E event*
- Poland arresting a man for flying drone over PM's office*
