Observation through a real-time satellite. Satellite map of Russia online
Satellite maps are compiled from photos of a different period of limitations taken from various satellite photo providers - such as NASA REVERB, USGS Earth Explorer and others. On the pictures, you can sometimes see the dates, but it is not a video stream in real time, but only a convenient collage.

Satellite map. Google Maps is perhaps the most popular. Although if you need to watch Russia, Yandex wins with accuracy.
Google Maps.
To switch to satellite mode, you need to go to the card and click the square "satellite" (now it is in the lower left corner). You can try to make it on the map below - I added a map here with a code for insertion (only square here without signature, as the total size is small):
- To focus the map to another place, click the left mouse button and pull the card to the desired side.
- To increase or decrease the scale of the map, twist the mouse roller (on this provision it is necessary to hold the Ctrl key, and big map - do not).
- On the big map you can find the desired location by entering its name or address in the input string.
The abandonment of pictures
Most of the pictures have the limit of 1 to 3 years. The date of the snapshot can be seen if you put the application Google Earth..
Yandex maps
In Russia, this card is better and more accurate, at least a scheme - what is located. As for themselves satellite photos, I approximately like Google for about several years.
Here is what you need to click to turn on the view from the button:

The photos are not worse here and no better - the satellite is a satellite, but the description of the objects loses, there are no newly built houses.
The evolution of cards, navigation and orientation on the ground occurs in our time. Now! The first travelers and pioneers used paper cards, cards drawn on stones, wooden planks, skin and other objects. Currently, few people represent themselves without electronic navigation, satellite cards, cellular ... New technologies are coming.
Let's try to deal with some features that provide us with technology in the field of observation and navigation at present. Look at the story.
Creating the first artificial satellites of the Earth
The idea of \u200b\u200busing satellites as repeaters arose long before they launched the Earth orbit first satellite.
For the first time to remove the aircraft in the upper layers of the atmosphere, engineers of fascist Germany tried, creating a managed rocket "Retribution Weapon".
Hitler's goals did not achieve their goals, but attracted the attention of many specialists to the development of missile weapons. People began to think about the possibilities of using managed missiles for scientific purposes.
One of the officers of the British army, the fiction writer Arthur Clark, in 1945 published an article in the magazine "Wireless World", where he proposed the principle of satellite communications and the possibility of transformation of such missiles to "unearthly repeaters".
On June 26, 1954, Korolev presented to the Minister of Defense Industry Dmitry Ustinov's memo " About the artificial satellite of the earth».
Work began on the project "ISS".
October 4, 1957 at 22 h 28 min. Moscow time "Satellite-1" was led into orbit. He began to feed the first signals from the space after separation from the last stage of the rocket. It was a metal ball with a diameter of a half-meter with the simplest radio transmitter.
In 1967, the system of Russian satellite TV "Orbit" began to operate. She allowed the Earth through an artificial satellite to transfer one central television program: "Channel One".
Satellite Cards in Real Time
The opening of the cosmos began with interactive cards - photographs of land received from the satellite. This significant event occurred on August 17, 1959, thanks to the American artificial satellite "Explorer 6". The era of satellite photography began.
Let us dwell on the services that have open access.
If someone is content with satellite cards in real time, they found those who seemed a little. Employees of the studio of interactive systems from "Georgia Institute of Technology" went on and offered real-time planet surveillance project In a three-dimensional review.
Depending on the time of day, you can see or very high quality broadcast, or a dark screen. If the second option, then you just need to repeat the attempt later, because it all depends on the satellite location at the moment.
Planet Earth Real Time Online
Also, services such as Google maps appeared, which remains the most affordable resource.
(To move around the map, zoom, reduce the map, image angle changes Use the navigation in the form of arrows and characters + and - at the top of the card. Try also, manage the card, holding the right mouse button)
View world map and photo from the satellite, determine the coordinates of any point of the planet, measure the distances between objects, calculate the area and pave the route using new satellite cards.
(Map can be increased or decreased)
If Google's cards provide static information, that is, snapshots from the satellite are not shown in real time, that is, devices that provide such an opportunity.
For example, with the help of a satellite receiver "Baikal" can be obtained photos and Satellite Cards in Real Time.
Satellite weather receiver Baikal is designed for receiving images of the earth's surface with meteorological vehicles located in low-bit and geostationary orbits operating in the frequency range of 137-138 MHz with frequency modulation of the signal in APT modes (NOAA15, NOAA17, NOAA18, NOAA19) and WEFAX (METEOSAT7, Goes). The receiver can be installed both in stationary and mobile objects, such as a boat, yacht, sea or river vessel, icebreaker or car. Reception of the picture is possible even while driving.
Services, Services, Opening ...
Through Google Card And other platforms enthusiasts invent more and more new services:
The development of services similar to Google projects is engaged in several startups. One of them, the American company SKYBOX, launching satellites into space. The goal is to make observation of real-time land more affordable. The company has demonstrated its vision of the future project, which shows the Chinese International Airport Suddu, shot by the SKYBOX satellite.
At the moment one satellite works in orbit. Total is planned to start 24 satellites, to cover the entire planet. The satellite weighs only 120 kilograms, and its size is 60 * 60 * 90 centimeters. Shot details - up to 90 centimeters per pixel.
To develop this system, navigation systems, satellite repeaters, webcams, services such as Google Earth and Microsoft Virtual Earth will be used.
Satellite world map allows you to quickly move across the planet between any settlements. Detailed map Peace from a satellite in Russian:
Examine a schematic card or switch to the world map from the satellite in the lower left corner of the map. Conceptual map of the world - This is the plan of the countries of the world and cities with street names and house numbers in Russian. On the schematic map of the world are attractions and tourist numbers, location of train stations, shops, restaurants and shopping centers, map road roads cities. Satellite map of the world allow you to consider photos of the city from the satellite thanks to the pictures from google service Maps.
You can get closer online card, scaling it to streets and houses of houses. To change the scale, use the "+" icons (approximation) and "-" (distance) located in the lower right corner of the map. You can also bring closer or remove the map using the mouse wheel. The left mouse button brings the map, right - removes. The mouse can move the interactive map in all directions, grabbed the left mouse button for any place on the map.
Interactive world map online It is a very convenient and modern guide to explore the city, its districts and attractions, hotels, recreation and entertainment sites. Online world map can be an indispensable assistant for you on a self-journey. An interactive map is provided by the Google Card service.
How to create satellite maps of the world:
The satellite, passing over the planet, scans the ground surface and with the help of the software cards are compiled. More recently, a few years ago, satellite cards showed the surface of the planet from a height of several kilometers. Now the technologies allow you to make satellite cards from a height of several meters, and in the near future technology will allow you to create satellite maps with detail up to 30 centimeters.
What to see on the world map from the satellite:
First of all, people are looking for their country on the map, their hometown, the street and the house in which they live. To do this, you can bring the schematic map of the world to your city, and then enable the "satellite" mode in the lower left corner of the map. In the same way, you can travel throughout world countries online, studying the sights of countries and cities in real time. Popular places that are often looking for satellite map: Reichstag in Berlin (Germany), Athenian Acropolis in Greece, Egyptian pyramids, Italy - Colosseum in Rome (Ancient Roman Arena Gladiatorovskiy Battle, Peterhof in Russia (west of St. Petersburg), Statue of Liberty In the USA - a symbol of America, Eiffel Tower in Paris (France), the Great Wall of China.

What are the possibilities of use satellitesflying over our heads in real timeyou know?
We can simply observe them, we can observe the earth with the help of special services, we can calculate the coordinates and get pictures of the area.
In addition to the above static map of the Earth from the satellite, you can use the Google Planet Earth's service to view or this is an interactive map:

The possibilities of satellites today are just fantastic. It turns out, there is another no less interesting activity - Satellite fishing!
If you have:
1) satellite antenna
2) Computer DVB tuner (DVB-PCI tuner, DVB card)
You can go fishing. But what, can we catch and what is the meaning?
And the meaning is this - sending a request for the issuance (download) of any file you send a request to a special server, the answer also comes through the satellite on the receiving plate. The request sends one one, and someone can accept it, because the satellite does not know where a particular user is located and transfers information to everyone who falls into the zone of its coverage. In order to get the file, you need special card for receiving a signal from space. The map has a unique number by which the satellite identifies the recipient, allowing it to receive discrete data. In turn, "Fisherman" catches the whole stream, all the user information from some provider. To catch from this thread to catch something worthwhile, special grabers programs are needed, in which there are filters where you can specify file extensions, size, etc. The only robers define the file not by expansion, but according to the file signature, therefore it will additionally need to download codes with filters. You also need renamers, to sort files by catalogs, removing unnecessary and clones.
Who knows, maybe you will be able to catch something "big" or stumble upon information from the "Top Secret" section, which will bring some romance and adventurous notes into your life.
Allow to obtain spatial information about the earth's surface in visible and infrared ranges of electromagnetic wavelengths. They are able to recognize the passive reflected radiation of the earth's surface in the visible and neighboring infrared bands. In such systems, radiation falls on the corresponding sensors generating, electrical signals depending on the radiation intensity.
In optical-electronic DZZ systems, as a rule, sensors with constant line-up scanning are used. You can highlight linear, transverse and longitudinal scanning.
The full angle of scanning across the route is called an angle of view, and the corresponding value on the surface of the Earth - strip width.
A part of the data flow received from the satellite is called the scene. Schemes for cutting flow on the scene, as well as their size for different satellites, have differences.
Optical-electronic SDP systems are pulled in the optical range of electromagnetic waves.
Panchromatic Images occupy almost the entire visible range of electromagnetic spectrum (0.45-0.90 μm), so they are black and white.
Multispectral (Multiple) Extraction systems form several separate images for wide spectral zones in the range from visible to infrared electromagnetic radiation. The greatest practical interest is currently presenting multispectral data from the new generation spacecraft, among which Rapideye (5 spectral zones) and WORLDVIEW-2 (8 zones).
Satellites of a new generation of high and ultra-high resolution, as a rule, are shooting in the parchromatic and multispectral modes.
Hyperspectralextraction systems form images simultaneously for narrow spectral zones on all parts of the spectral range. For hyperspectral shooting, it is important not the number of spectral zones (channels), but the width of the zone (the less, the better) and the measurement sequence. Thus, the film crew with the channels will be hyperspectral if it covers the range of 0.50-070 μm, while the width of each spectral zone is not more than 0.01 microns, and the film creation system with the 20th individual channels covering the visible region of the spectrum , near, short-wave, middle and long-wave infrared areas will be considered multispectral.
Spatial resolution - The value that characterizes the size of the smallest objects distinguishable in the image. The factors affecting the spatial resolution are the parameters of the optical-electronic or radar system, as well as the height of the orbit, that is, the distance from the satellite to the removable object. The best spatial resolution is achieved when shooting in Nadir, with deviation from Nadar, the resolution is deteriorating. Space snapshots may be low (more than 10 m), mean (from 10 to 2.5 m), high (from 2.5 to 1 m), and ultra-high (less than 1 m) resolution.
Radiometric resolution Determined by sensitivity of the sensor to changes in the intensity of electromagnetic radiation. It is determined by the amount of gradations of color values \u200b\u200bcorresponding to the transition from the brightness of absolutely "black" to absolutely "white", and is expressed in the amount of bit on the pixel image. This means that in the case of radiometric resolution of 6 bits / pixel, we have only 64 grades of color, 8 bits / pixel - 256 gradations, 11 bits / pixel - 2048 gradations.
