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.

Can a GPS tracker deal with welfare fraud?

The welfare fraud case has often become a hot topic among Swiss politicians and the general public. A recent report that Swiss private investigators could use GPS trackers to track welfare fraudsters could solve the problem of welfare fraud.

In 2016, the European court of human rights made a clear decision that Swiss law on the use of GPS tracking equipment to monitor the criminal suspects is lacking the legal basis. On March 14, according to the report, the Swiss parliament has decided that a GPS tracking device can be applied to allegedly rich look poor to defraud welfare subsidies, abuse of fraud investigation, this will give the welfare fraud molecules, they can’t reuse disability welfare fraud. The use of GPS tracking devices by private investigators requires approval from relevant agencies.

Reports said, citing Swiss SRF public television news, local time on March 12, the Swiss national hospital and seat both houses of congress have voted to approve the use of GPS to deal with the laws of the criminal suspect. Can a GPS tracker be used to solve the problem of welfare fraud? The vast majority of Swiss people feel that they cannot solve the problem completely and only partially solve the problem. We know that GPS trackers rely on GPS signals, and if GPS signals are blocked, the fraudsters will be able to move freely without being tracked. As the legitimate use of GPS tracker in welfare cases, those illegal a lot of scam artists began to think of some way to solve the problem of tracking, on the Internet, they saw the shielding equipment sales of GPS signal, the GPS jammer.

The GPS global positioning system became the focus of debate in the Swiss parliament on Sunday, the report said. A GPS the tracking device, a private investigator able to successfully locate precisely someone’s location, so as to determine whether the other proclaiming himself as the case of severe disabilities are able to drive a car on his own.

The passage of the law also means that private investigators can be allowed to observe and actively monitor welfare fraud suspects in real time. But unlike recordings and video recordings, detectives must be able to use tracking technology at the bottom of the court’s approval.

Swiss interior minister Alan bell said, although the federal commission for defrauding the disability benefits people closely monitored idea has generally been supportive, but also have some concerns with these measures, or to privacy infringement. He noted that insurance companies should not be allowed to act beyond the rules of the procuratorial organ. In addition, the existing law is still too vague about the definition of “technical equipment used for positioning”, which is now understood to include, in theory, technical equipment such as drones. As for the tracking of drones, you can also take appropriate measures. A high-power drone jammer is something you should consider buying. But the unmanned aerial vehicle (uav) jammer due to its powerful features, design of the heavier, not conducive to carry, in a word, always more than problems, as long as you want to avoid tracking, there is always a better way to solve.

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.

Talk about the future of 5G technology

Now every telecom company is releasing more news about 5G signals in advance. The news and promotion of 5G signals will not surprise many people, as the mobile world congress takes place and changes from consumer performance to business activity.

There is so much news on the Internet about 5G signals, which makes 5G so fabulous, but is 5G really the change of signal network? This issue was discussed by ZDNet and the leaders of the field, who focused on the impact of 5G on data collection, storage, processing and application, and interaction with cloud and AI. See here you can know the future 5G will be involved in how broad field, also know that 5G is so powerful, will let so many telecommunication companies to study development vigorously.

Will 5g network faster?

Usually we are concerned about the speed of network speed, so 5G will make our network faster? Of course, the sales of 5G are mainly focused on improving the advantages of network speed. But network speed is the key to edge analysis and smart use cases, such as the Internet of things and self-driving cars?

Sierra Wireless is a global leader in the Internet of business, with products for utilities, smart meters, and PCS and tablets to vehicles. The speed of the web is good, but what are the benefits of getting more data if you’re doing something careless about it? At a time when the Mesosphere has been heralded as a technology pioneer by the world economy BBS, its chief executive has mentioned something in marginal computing and autonomous/connected cars. Most of the Mesosphere is the company behind DC/OS, one of the top platforms for building, deploying, and resiliently extending modern applications and big data. Speed is not the point. One thing that can change is reliability. That’s what the CEO of Scale, Alexandr Wang, thinks.

“In the case of low network speed, the communication service provider must proceed to the edge computing device for data cleansing, cleaning and optimization near mobile terminal devices. The edge network is faster and can provide more data for high-density environments, thus achieving the evolution of use cases involving edge analysis and intelligence. ”

Reliability is critical.

The car is becoming a large computer on the wheel and is equipped with many sensors, such as lidar. The laser radar sensor emits a light pulse and measures the reflection back to determine the distance between objects, creating an accurate 3D map of the environment around the car. These sensors and other necessary systems, such as GPS, lead to estimates that each autonomous vehicle will produce and consume approximately 4TB of data every eight hours.

“Most self-driving vehicles are in the development of the technology, and to minimize the connectivity of the Internet, most of the time they report to the Internet while driving specific statistical data, but the algorithm and map has been loaded into the car in advance, I don’t think the Internet speed is a huge limiting factors, unless it becomes more reliable”.

Future self-driving automobile application technology will be a lot of, including the now say about 5 g, also must use the other GPS technology, need GPS for car to provide accurate location, to keep the safety of the autopilot is higher. The application of 5G technology is likely to be interfered with by a variety of factors, such as the magnetic field, just as GPS signals are disrupted by GPS blocker jammer.

Scale is the manufacturer of the Sensor Fusion Annotation API for lidar and radar point cloud data, providing power for self-driving cars, drones, maps, etc. Scale provides training data for some of the world’s most advanced automotive companies, such as general cruise, English alphabet, Uber and Honda. Wang added:

“The biggest problem is the reliability of the connection, and if the car depends on the cloud processing steps, there will be a failure to connect and potentially compromise passenger safety.

5G connectivity must prove highly reliable in testing to convince any car manufacturer that they can rely on it in any real world environment. It must be cheap, reliable and fast. Quick features to provide value without causing delay processing time.
