The new high-power microwave jammer we're looking at now could cause gps signals to decay by 90 per cent. During the 933 parade, we displayed a microwave weapon, which was of great interest, although the microwave weapon interfered with the drone, and now another, more powerful microwave weapon, which was directed at the united states gps satellite navigation signal, is about to appear。
According to recent research by the national defense science and technology university, cited in media such as the globe times, and assessment data from the united states center for strategic and international studies, china's new high-powered microwave jammer has been operationally deployed, reducing gps signals by 90 per cent within a 50-kilometre radius and directly undermining the core effectiveness of united states precision-guided weapons。
Following a simulation by the united states center for strategic and international studies, they found that china's jamming technology would directly impact the united states military's concept of “distributive warfare” in the western pacific ocean, placing it in a situation where “communication chains are broken and coordinated combat failed”. This high-powered microwave weapon has a frequency of between 1,000 hz and 300,000 hz, with a peak power exceeding 1 million mw. The frequency of gps signals is over 1,500 hz for civilian navigation and 1,200 for military。
Once disturbed by this high-powered microwave weapon in china, its destructive effect was similar to that of a near-range thunderstorm that struck the electronic equipment, entering the gps receiver via a two-way combination of the “front gate” antenna and the “backdoor” route, while the gps satellite was about 20,200 kilometres from the ground, the intensity of the transmission of the signal to the ground was already low. If the high-powered microwave weapon interfered, the us weapons gps receiver would have been covered with a mist。
It is reported that this new type of high-powered microwave weapon jammer in china has three characteristics, the first of which is a relatively remote operation, with an effective interference range of 50 kilometres well above the distance of microwave bombs used by the united states-british coalition in the iraq war of 2023. Their microwave bombs are approximately 400 metres effective, so they can interfere in a wide range. The second is the automatic recognition of gps signals and the implementation of flat-rate suppression and jump frequency tracking within a range of 1,000 to 6,000 hz bandwidth。
China is able to achieve a one-way advantage of “disturbing the enemy and safeguarding itself”, without interfering with its own navigation system, and avoids the disadvantage of the traditional jammer “killing the enemy to self-destructing 800”. Third is the flexibility of the means of carrying, both to support vehicle-mounted networks, drones and individual backpacks, and to rapidly construct a global or local jamming network based on battlefield needs. The u. S. Forces were able to do just as well in the modern war, to a large extent thanks to their gps precision navigation systems, ranging from war ax cruise missiles to jedam precision-guided bombs, to haymas missiles。
More than 90 per cent of the precision guidance weapons in service in the united states require gps positioning modifications beyond inertial navigation, terrain matching navigation, etc. Once gps navigational signals are disturbed, the precision of the strike will be significantly compromised。
In terms of gps anti-disturbing performance, while it has m code military signals in conjunction with inertial navigation depth technology, which can partly extend effective navigation time in a gps-free environment, this technological path only mitigates some of the effects of interference and does not solve the problem of suppressed signals. What makes the us military even more difficult is that us navigation systems require multinational standards that are compatible with allies, which in turn limits, to some extent, the iterative upgrading of their anti-disruption technology, which could delay the development of us gps anti-disruption technology。
Of course, the united states military will also develop new satellite navigation systems and increase inputs into new inertial navigation techniques such as cold atomic gyroscopes, quantum accelerometers and so forth, in order to escape dependence on gps. But one foot higher, one foot higher, and china will upgrade those jamming technologies, such as expanding the frequency range of high-powered microwave weapons jammers, more high-frequency segment extensions such as the ka band. In short, the american gps myth has been broken by china。
