What if all of the satellites vanished overnight?

  All of humanity's artificial satellites mysteriously vanish one day, with no warning or apparent cause. A small group of government and business operators were the first to grasp the problem. But, before they have a chance to understand what has happened, millions of people lounging on their couches notice something is wrong. Satellite television, which is broadcast from or routed by satellites, dominates the market for international programmers as well as some local stations, hence its departure has a global impact. Travelers by air, sea, or land will be the next to be affected, as global positioning, navigation, and timing services have all but disappeared. Pilots, captains, and drivers must use analog instruments and maps to identify their locations. Aircraft, ships, and ground vehicles are all forced to come to a halt, be grounded, or return to port. Meanwhile, air traffic controllers are faced with a difficult task: preventing jet crashes. Most of the world's traffi

Fixed Wireless Internet vs Satellite Internet Access: What are the key differences?

  Here, we're going to talk about the difference between fixed wireless internet  and satellite service.  So what's the difference between fixed wireless internet and satellite services? There are some very key differences between fixed wireless internet and satellite internet. One of the most significant of those is the distance at which the signal has to travel. So with fixed wireless internet is generally 10 miles or less.  Whereas with satellite internet, most satellite internet, the data travels over 22,000 miles. That's a pretty long distance. Even with Starlink and some of the low orbit satellites, it's still going hundreds of miles. So that brings me to the second point,  which is that latency is introduced with as long distances. So there's a delay when someone clicks on something when someone is on a voice call or a video call and  says something has a delay till that data can get out to the internet  with satellite internet. So things like gaming, voice

Satellite Maintenance in Space: What's Next?

Satellite Role In Television Broadcasting

  Satellites have revolutionized the way that we humans live.  we are going to explore how satellite television works  and also the big money flows associated  with this broadcasting business. Here,  we will also explain the interesting reason  why there is no buffering of your TV broadcast in the way that internet videos are buffered.  To understand satellite TV broadcasting properly, we first need to have some basic knowledge  about the parts of a satellite  and how a satellite moves. As you can see, the Earth revolves around the Sun in an elliptical orbit,  and the Earth also turns on it's own axis. You can see that this axis of rotation is  not perpendicular to the elliptical orbit surface  but slightly inclined, as shown.  For satellite TV to work,  the satellite should not move relative to your house.  This means that the satellite should rotate at  the same speed as that of the earth.  Which means, it will take 24 hours to complete one cycle.  Let's work out

The UK government intends to reduce red tape associated with 5G deployment and increase mobile phone connection

  As part of a new programmed to remove red tape and install additional 4G and 5G equipment in the UK, more mobile network equipment will be installed in street lamps, bus shelters, and traffic lights to assist enhance mobile coverage. The UK government has announced that eight winning projects will receive funding from the £4 million Digital Connectivity Infrastructure Accelerator (DCIA) to investigate how digital software can help local authorities streamline processes when telecoms operators request access to publicly-owned buildings and curbside infrastructure.   Road signs and CCTV poles can help with 4G coverage, but they're also important for 5G, which requires a larger number of smaller 'cell sites' (where antennas and other telecoms equipment are placed to form a network) to ensure seamless coverage and meet rising demand for connectivity, as per the government.   The government claims, however, that obtaining the information needed to verify a structure's

Role of satellite in our lives

  As an image is often considered the life line in any medium of communication, it has been with all its advantages and disadvantages as being one of the most useful kinds of media for the human race with the aim not only to make it easier but also more effective by utilizing it in different ways. The satellite tv has become a source of data which allows us to see and analyze every little thing. With that we can see what people are going to do on the streets of our cities or even watch what they are doing. That gives us some information about how many people are walking. What kind of food they are eating. How much clothes they have. The role of this kind of information is very important in today’s society. But here, we will talk in detail the function of such a satellite. On the other hand, let’s talk about the function of such a technology. Why use satellite? What advantages do you see? And, why we use it? Let us start with an introduction to the topic of satellites. The Advantages Of

Satellites in Agriculture: Using Artificial Intelligence to Improve Satellite Imagery

  satellites are observing earth24 7 and historical imageries of the farm you manage are available from multiple satellite sources this historical data could give you some specific insights about what happened and how it happened in the farm historical data could also be fed into artificial intelligence models to predict what will happen let's illustrate this with a wheat and canola farm in Saskatchewan Canada knowing the coordinates of the farm we cured its historical data of 2015 to 2020 whenever cloud coverage of the scene was less than 30 percent we evaluated three indexes normalized difference vegetation index or ndvi green chlorophyll index or gci and normalize difference water index or ndwia low value on ndvi means lack or poor vegetation for gci it means plant stress and forndwiit means water deficiency in the farm we collected satellite data from may 15 2015just before summer started and continued until the end of the harvesting season, in2020and plotted the historical ve

Definition, future technology, and study on artificial gravity

  Artificial gravity has the potential to transform space exploration and off-planet tourism. The generation of an inertial force in a spaceship to simulate gravity is known as artificial gravity. This concept is frequently seen in science-fiction shows such as "Star Trek," but it is not confined to them, and researchers are now working on ways to manufacture artificial gravity in space. Artificial gravity would not only simplify the next era of space research by making work easier, but it would also be critical for eventual space tourism. Because the consequences of microgravity in space can be harmful to humans, artificial gravity may become increasingly important as we consider longer crewed trips, such as expeditions to Mars . Albert Einstein claimed in his 1905 theory of special relativity that gravity and acceleration are identical. That means an astronaut would feel tied to the floor in a rocket travelling at 31.19 feet per second (9.81 metres per second) squared

Satellites aid in the monitoring of underground water storage..

  Groundwater is an unseen but critical resource to our daily lives .   Fresh water makes up only 2.5 percent of the total amount of water on the planet. About a third of the 2.5 percent is available as groundwater, or subsurface water reserves. Fresh water makes up around 1% of the Earth's surface, in rivers, lakes, streams, and reservoirs. The remainder is encased in ice. For billions of people, groundwater provides a source of drinking water. Aquifers provide drinking water to roughly half of the world's population. Groundwater is also an important source of crop irrigation water. Much of the water needed in sewage systems and industrial processing comes from underground sources as well.   It's important to track changes in groundwater since even minor changes in volume can have significant negative implications.   Despite the fact that there is a lot more water underneath the ground compared to the water on the surface, only a small quantity of it can be pumpe

Using aerial photos, a neural network calculates forest height.

  To monitor the natural environment, infrastructure, and timber supply, researchers built a neural model to determine the height of trees .   According to this research, a neural network could scale up trees from satellite pictures. Many people demand precise estimates of forest tree size, from environmental scientists to civil engineers to wood industry workers. This data is crucial for determining how much carbon dioxide the trees absorb from the atmosphere, if they pose a threat to power lines, and how much timber is available for logging. Because drone technology is unsuccessful in big and difficult-to-reach areas, these estimates are now based on satellite images and several cameras spanning various bands of infrared light. However, multispectral data is both scarce and costly to get. Researchers from the Moscow-based research institute Skoltech may well have discovered the ideal solution, since they were able to train a neural model to reliably and cost-effectively mea

Pollinators can now be saved using satellites and drones

Researchers claim that satellites and drones can provide crucial information to protect pollinators.   According to a new study, new ways of utilizing these technologies to track the availability of flowers might be paired with behavioral studies to see the world through the eyes of insects. Human activity is affecting landscapes in ways that influence all pollinators, and the blooms available to insects vary from day to day and place to place. The South Devon Area of Outstanding Natural Beauty (AONB) and the University of Exeter study team hope that their method will help us understand these changes and lead to better conservation. Dunia stated, "Recent advancements in drone and satellite technologies have created new opportunities." "Drones can now provide exquisite details of a landscape, down to the scale of individual flowers, and when combined with satellite imagery, we can learn about pollinator food availability across a vast area. "This, in co
