Military satellite positioning system of jamming and anti-jamming performance

So far, only three countries in the world can provide military signal of satellite navigation and positioning services, are free to use their own satellite navigation and positioning system to develop its own satellite guided weapons, they are China’s beidou, the us GPS and Russian glonass. Advanced technology can improve the security of the country.

Due to the importance of military satellite positioning system, all military powers attach great importance to the interference and anti-jamming performance of satellite positioning system. So, if the GPS and the beidou satellite are disturbed on the battlefield, can the two sides fight normally? In many ways, GPS satellite positioning and GPS tracking are important for military.

China’s armed forces and military researchers have profound experience over the years, whenever China must carry on the large-scale military action or large domestic weapon test, theater over the GPS satellite signal is always “happen to” some fault occurs, either by intermittent close or reduce strength. This results in the error of satellite positioning and navigation, which can easily cause errors and can not accurately obtain the actual data information.

Ukrainian civil war and the war in Syria in recent years, western forces found in Russian theater GPS jamming ability, can in a period of time will weaken or completely blocked the whole civil war zone of GPS signal, many civil aviation organization and sailing ships of unstoppable report, civilian GPS is suspected Russian interference, so, in recently warned, be wary of Russian troops on the navigation system of electronic warfare capabilities.

Both Russia and China attach great importance to GPS interference, and the production of GPS jammer can interfere with ordinary military GPS receivers. The simplest way to do this is to delay processing of the GPS signal and then broadcast it, when the enemy’s GPS receiver receives a false signal.

It doesn’t seem to complete its shielding, the latest GPS satellite is has the capability of anti-interference in two band released two military navigation code, can constitute four work modes in actual combat, which can greatly improve the ability of anti-jamming. America’s military GPS receiver has a important anti-jamming technology, is “gramm application components and SAASM deceives module, is a kind of standard electronic plug-in, can be inserted into the aircraft, warships, missiles and all kinds of weapons.

In addition, in order to improve the operational performance of military GPS, the U.S. military will deliberately reduce or even close the civilian signal of the enemy theater in wartime, and improve the intensity of military signals. Beauty on April 14, Britain and France, for example, to use cruise missiles to Syria launched a massive air strikes, U.S. troops on the evening of April 13 to 14, in the morning to Syria war zone of L2 suddenly increase military band of GPS signal, signal intensity is about a times more than usual, the moves are China’s beidou system foundation continuous detected, concurrent warned.

So it’s not easy to reliably interfere with military GPS signals in the battlefield.

Finally is to emphasize that in the field of weapon application, GPS satellite guidance system is not people imagination of so magical, is based on GPS as supplementary guidance, very few weapons simply use GPS as the only guidance system. Generally, GPS/INS combination guidance, namely inertial guidance +GPS global positioning system auxiliary guidance. The output frame rate of INS inertial guidance is high, and the crystal vibration time is accurate, so the guidance is based on the inertial system, but the drift of INS is large, and the accumulation error needs to be corrected by GPS.

GPS satellite navigation is used in the automotive field of jamming devices

GPS satellite navigation is the most widely used navigation technology in life, and GPS satellite signals are used in many countries. This kind of navigation technology is most obvious in automotive applications. Driving a car in a strange place requires satellite navigation to provide you with an accurate guide to where you want to go.

At present, in the field of satellite navigation system in car usage is facing challenges – in the city, users often feel navigation system and interrupt the line of sight of interference, but, in fact, the city is the most accurate and reliable navigation need:

When the vehicle passes through the tunnel, the navigation data will be lost, and when the vehicle exits, it usually takes a period of time to reorient to the correct location outside the tunnel.

The accuracy of navigation becomes limited or even poor as the drivers pass through the city’s high-rise buildings.

In addition, high-rise buildings can reflect the global positioning navigation system (GNSS) signal, further weakening the signal definition.

Not only that, with the development of GPS jammer, many current owners of the whereabouts of protection consciousness enhancement, the privacy of their whereabouts for car, they are more attention, in order not to be tracked, they for their car to buy a portable GPS jammers, in need of protection whereabouts open, it is convenient for them. If you navigate from his side at this time, your navigation information will be blocked, the data is not updated, need to stay away from the satellite signal interference sources, update your navigation data can be normal. When the signal is blocked, your location is not monitored by the relevant traffic law enforcement authorities, and it may be advantageous if you are speeding.

But technology is always improving. The global navigation satellite system has begun to innovate.

GPS satellite navigation is convenient for travel in unfamiliar cities, but it is also easy to track other criminals. GPS jammers prevent GPS satellite signal tracking, for the protection of your privacy is very convenient, it also makes more and more favored by the owners, in their car, almost all of them are equipped with a portable, easy to hide the interference of the equipment, the need to avoid tracking when open.

The application of signal jammer in life

Mobile phone signals shielding device is a kind of block device, can effectively shield the CDMA, GSM, DCS (1800 MHZ), PCS (1900 MHZ), td-scdma, PHS, 3 g mobile phone signals, WIFi, and 4 g phones etc all communication signals. Mainly aimed at all kinds of examination room, school, gas station, library, meeting rooms, cinemas and theatres, churches, court, hospital, government, military, prisons, country the secret service area and other places of all to ban the use of mobile phones.

In life, many owners often is one click remote control key is in a hurry to leave, did not carefully confirmation about the safety door lock, in reality there are a lot of examples may lock the door doesn’t really. It is illegal to use the signal jammer to implement the theft of the illegal act, is not allowed.

Signal jammer application in life there are many examples, schools for students can put more effort into learning, the ban on cell phone use in schools have installed mobile phone signal jammer, its purpose is not only in this way, it also for a number of important exam escort, to ban the use of mobile phones and other electronic equipment to cheat behavior. In addition, the use of mobile phones for students in the class, the cellular phone affect the behavior of the teachers in class, is not allowed, can receive the signal jammer equipment shielding, can only use mobile phones to do something can’t connect to the Internet, such as browsing download good novels, listen to the local music.

In prison, cell phone signal jammers for cyber criminals is pain, this kind of equipment to make them away from the network, for the whole people addicted to the Internet, can not access the Internet will make them uncomfortable. The prison jammer, on the one hand, is meant to protect the security of prisons, and on the other hand, to make cybercriminals better reformed. Prison not only use a mobile phone jammer, also used for unmanned aerial vehicle (uav) uav jammer device, we heard of the use of unmanned aerial vehicle (uav) will etc to smuggle drugs into prison for criminals use, this is absolutely prohibited behavior, prison officials discovered this phenomenon, therefore, take the uav jammer device to stop at once.

Military use signal jammers are plenty of examples, such as we are familiar with GPS positioning system will be installed on the missile, interference with GPS signals is very important, the wrong or there is no GPS signal, then the GPS missile will not be able to accurately hit the target, the military needs. In the same way, drone strikes and drone reconnaissance require drone jammer to keep drones out of the area.

The Russian air force base in Syria has been hit by a drone strike, causing damage to the aircraft. Russian military later responded that they had by capturing the drones, deciphering the related data, lock the unmanned aerial vehicle (uav) control location, and fire coverage, targeted to revenge. How important it is to protect drones.

The U.S. air force drill may be a GPS failure

If your GPS navigation system this month in the west of the road trip can’t accurate navigation, so there are two reasons, one is your GPS navigation system is broken, another possibility is that the air force’s GPS signal jammer.

In 2018 January 26 solstice during February 16, the U.S. air force will regularly in the western states blockade GPS signals over a large area, and military “one set of the primary air military game a” red flag 18-1. Use a powerful GPS jammer system to completely block GPS signals in the area.

Drones are part of our future! Let drones fly, but if a drone is in the wrong hands, we need to address a huge security threat.

U.S. government hunt reveals the unmanned aerial vehicle detection system planning in urban set to create a system to track down suspicious unmanned aerial vehicle DARPA low-flying unmanned aerial vehicle (uav) in large cities the platform will be using unmanned aircraft and sensor behind a suspicious vehicle nodes will cover 70000 miles, costs less than $10000.

The red flag exercise is an advanced large-scale military training series of activities to meet and improve the real-time operational conditions of simulation pilots and weapon system officials. Every year since 1975, the U.S. air force has held a red flag meeting, a major military activity aimed at military drills. The exercise took place at a series of weeklong meetings at the Ellis air force base outside Las Vegas.

The global positioning system has become an important part of modern technology. The power failure is designed to challenge air and weapon personnel to be familiar with alternative navigation technologies in realistic combat conditions. GPS technology is widely used in military, the GPS signal has very important meaning for military, this may involve a survival of the army, so very much pay attention to the exercise of the American air force.

Exercise this year is the red flag 42 years one of the biggest games in history, in addition to the U.S. air force, including from the United States Marine corps, the United States trust Allies and British aircraft and crew. It shows how much the United States values the exercise.

How will this exercise affect civilians? Flying Mag, according to a report by the global positioning system of a power outage will be extended to include California, Nevada, Oregon, Wyoming, Arizona, Utah, Colorado, Montana and new Mexico, in some states around air force base in Nevada, do not match the GPS access may result in the plane. Ground vehicles.

“We are using the red flag 18-1 to try something new and different,” said col. Michael Mathes, commander of the 414th combat training squadron. “This is the largest red flag ever, highlighting the balance between training efficiency and task efficiency.”

During the exercise, GPS signals in the exercise area will be disturbed, and if you find that your mobile navigation is not accurate, it will be affected by them.

For using GPS signal equipment, such as mobile phones, smart watches, intelligent bracelet and so on, also may not work properly, if you are in the Shadowed by GPS tracker, you’re lucky, you can in a short period of time to avoid the GPS tracking. In fact, if you are tracked, you can also use a GPS jammer device.

Concept and characteristics of UHF/VHF jammer

UHF, or UHF, refers to the frequency of radio waves at 300MHZ to 3000MHZ. This is the highest frequency used in television broadcasting. UHF is widely used in walkie-talkie, bluetooth, wireless network, mobile phone, close communication fields such as military radio.

VHF (VHF), short for VHF, refers to the frequency of radio waves of 30 MHZ to 300 NHZ. VHF is higher than HF (high frequency) but lower than UHF. VHF is mainly used for radio and television, as well as aviation and navigation channel of communication. According to the characteristics of uhf and VHF, we have developed uhf/VHF jammer.

UHF/VHF jamming machine is specially designed for use in a specific frequency range block communication channel, is widely applied in specific areas. In UHF/VHF jammer, solved the radio frequency (rf) and radio frequency unexpected sound interference, wireless network, to ensure that the broadcast and the security of aviation safety.
