With the rapid development of the commercial UAV industry, there is growing concern about the impact of jamming on UAVs by bluetooth blocker devices, which, by transmitting high-powered radio signals, are capable of blocking the control and data links between UAVs and ground stations, forcing the UAVs to lose control, interrupt their missions or even crash. This poses serious safety risks and economic losses to commercial drone applications, and the industry must take strong countermeasures.
Technical countermeasures against Jammer
The first step is to enhance the anti-jamming capability of UAVs at the technical level.
(1) Apply frequency hopping, spread spectrum, coding and other anti-jamming techniques to improve the anti-jamming ability of data transmission.
(2) Optimize antenna design and signal processing algorithm to improve reception sensitivity and reduce BER.
(3) Equipped with the intelligent system of automatic detection and gps jammer for sale avoidance to intelligently identify and bypass interference sources.
(4) Adopting multi-mode redundancy design, in case of interruption of some data links caused by Jammer, it can still switch to other working modes.
Enhance UAV flight control capability
The next step is to improve the fault tolerance and emergency mechanism of the UAV itself.
(1) Enhance the autonomous flight control capability of the UAV itself, so that it can execute intelligent mission mode when the data link is interrupted.
(2) Design safe emergency return and automatic landing procedures to ensure the safety of onboard equipment and the UAV itself.
(3) Optimize the power management of on-board equipment to extend the working time and flight range.
Formulate relevant regulations and management policies
The final step is to adopt regulations and policies to regulate and supervise.
(1) Formulate laws and regulations for the control of Jammer devices and increase the penalties for illegal use.
(2) Designate flight zones that prohibit the use of 5G jammer devices for drone applications in important areas.
(3) Establish a monitoring and tracking mechanism for UAV flight control, and have the regulatory authority unify the dispatch of interference sources.
In general, the threat of rf jammer interference to UAVs exists objectively. The commercial UAV industry should improve the technical protection ability, and also need the government to introduce relevant regulations and policies to support, from the technical and management aspects to jointly maintain the UAV flight control safety, and promote the healthy development of the industry.
